Sustainable architecture: innovative and inspiring building design
From amazing abodes to centres of care and hard-working offices, we chart some of the world’s best examples of sustainable architecture, buildings that not only look good but also do good
The Learning Tree
The fragrant smell of timber, a slew of engaging toys and gentle lines and materials, and sustainable architecture principles are key components in the identity of The Learning Tree nursery - a new preschool facility in East London’s Romford. The timber-clad architectural interior design is the brainchild of emerging studio Delve Architects. The young practice, set up in 2017 by school friends Edward Martin and Alex Raher, was called upon to retrofit a former industrial building. This has now been transformed into a warm, welcoming learning space using durable design and natural materials - namely, timber, ply and rubber. Creating the space in just six months and working with specific budget constraints, the architects employed glazed partitions, timber screens, curved forms and bespoke joinery to customise the interior for their client, leading childcare and education company, Storal Learning.
Kura Kura Badminton Court
Studio Jencquel and Ibuku’s Kura Kura project is an architectural treasure tucked away in the mountains of Bali. At 200 sq m, this bamboo badminton court structure is a modest but intriguing feature of the leafy grounds of the Rumah Hujan Estate in Ubud, designed around sustainable architecture principles. Intended initially as a paddle tennis court, the project evolved organically into a badminton court, when Studio Jencquel founder Maximilian Jencquel realised that Indonesia’s national sport would be a more fitting addition to the estate’s grounds. Aside from being a visual highlight, the building contributes to a wave of striking bamboo-based architecture in Bali.
Hé Architektuur’s projects look primarily at rescuing the remnants of existing buildings. This, combined with the team’s inclination towards renewable, raw materials, means the resulting works often feel like a creative revival of bygone eras. The building that became the studio’s Karper project, in Molenbeek, Brussels, had served for years as a factory and office. Retaining the existing four walls and solid metal beam that runs through the centre of the building for support, the team added exposed wooden flooring. These elements, alongside huge windows and painted brick in subtle hues, give the house a light, honest feel. Four mezzanine-style floors create a flow between the spaces in this 330 sq m building, where interior walls are largely absent, making way for curtains and resulting in a highly flexible layout. One bathroom wall is replaced by tri-fold doors that open out onto the ground floor courtyard, and wooden stairs are tucked into corners, freeing up floor space on the well-connected levels. The façade combines an attractive mixture of period and contemporary design. A white brick loft extension sits on top of the historic body of the house, contrasting beautifully with the red bricks and adorned window frames below.
Enter Projects Asia cleverly used a sustainable structure to refresh a factory building in Belgium. Located in Waregem, the project reactivates a 300sq m mix-use space through ‘balance and calm.’ Wellness and an eco approach were also important and the architects decided upon installing a flowing rattan element, praising the natural material’s environmentally friendly qualities - it is entirely natural, renewable, and biodegradable. ‘The sculptural segments were designed in accordance with the functionality: lighting, seating and directional flow, all culminating in a large 8m high sculptural statement piece which illuminates the lobby and compliments the image of the brand,’ says the design team. ‘Furthermore, the rattan factory in Bangkok is powered by the people who work there. These structures are hand crafted by Thai artisans with generations of experience behind them. There is no ‘machine power’ involved in the making of the rattan. As you will see from the fabrication photos, it’s also people (ultimately team work) ensuring that the structures are safely hoisted into the containers for shipping. There is no electricity involved in this process, zero carbon footprint.’
A brand new energy-generating interfaculty teaching building has opened at TU Delft in the Netherlands. The work of Amsterdam based UNStudio, the structure is sustainably designed, using insulation, heat regulation and solar panels so that it harvests more energy than it uses during operation. It is also very flexible and compact. ‘The Echo building teaches by example. In this highly compact building, the use of space is maximised, while bringing students from different disciplines in closer contact. Not only can they condense their learning experience and learn from each other, but they can also learn from the building itself,’ says studio director Ben van Berkel.
Set in the Scottish village of Kippen near Stirling, and designed by locally based architecture studio Paper Igloo, this home was planned around the sustainable architecture of Passivhaus principles. The structure is located in a historical conservation area and faces woodland, and the architects reference this natural and layered environment by cladding the building in weathered timber. Conceived as a ’box within a box’ that enhances insulation, it also meets the demanding requirements of the Technical Standards Section 7: Sustainability Gold Level.
Made of Sand
A Devon cottage has been given a new lease of life through a considered extension by London-based architects Studio Weave. Made of Sand, as the project was named, is the transformation of a traditional stone structure into a modern retreat, by the addition of a two-storey timber pavilion on one end. The secluded property in the Blackdown Hills now has extra capacity to host guests and can also act as a dedicated creative space for its owners, celebrating the flexible architectural addition that marks a new era to the historical original property’s life. The timber structure can be accessed and inhabited separately from the main cottage, which accounts for its flexibility in use. Its forms are unmistakably contemporary, but thanks to a careful balancing of volumes, façade rhythms, and choice of materials (such as the exterior’s external Red Western cedar panelling, but also the clay, terracotta, and brass found inside), it still feels at home in the natural and historical context of its site.
BakerBrown Architects has an award-winning reputation for sustainable architecture, pioneering ways of reducing a building’s footprint through meticulous design, careful use of resources, and thoroughly practical and attainable methods like insulation and the use of local materials and trades. In a similar vein, its latest work is a sustainable extension that makes the most of a unique site that brings together past, present and future. The practice’s most recent project is a conversion of a long, low, gabled dwelling house in the south of England. The original structure was once the village forge, making all manner of metal goods for local farmers and businesses. It was subsequently converted into a house and the surrounding neighbourhood upgraded to a Conservation Area.
Inhabit Queen’s Gardens
The most sustainable thing to do for the planet is probably to avoid travelling much; but if travel seems inevitable, planning a journey in the most eco-friendly way is definitely the way to go. If you’re London bound, the newest offering in the Inhabit family, the chain’s Queen’s Gardens location, could fit the bill nicely. The newly opened Inhabit Queen’s Gardens, designed by Holland Harvey Architects, is a project conceived using key principles of sustainable hotel design – without compromising on comfort or style. In fact, its sustainable architecture is so well embedded in its making that it’s an aspect you don’t even notice during a visit – natural materials aside. For the architecture studio behind it, headed by Richard Holland and Jonathan Harvey, this was not the first foray into hotel design – they were also behind Inhabit’s other London location, in Paddington. But it’s the first time they have been able to take their sustainability ambitions to this level, working with the more environmentally friendly overall approach of restoration and redesign (as opposed to building anew).
If it is the clean, modernist shapes of Knox Bhavan’s new March House that first signal it as an exceptional contemporary home, then its strong eco-credentials and idyllic countryside location are sure to cement its position as a gentle but also truly forward-thinking piece of residential architecture. The project, recently completed on a natural floodplain on the banks of the River Thames in the UK, is a cleverly prefabricated, flood- and future-proof home that brings sustainable architecture to this part of the picturesque stretch of the river. March House was built as a private home, created using a modern, prefabricated cassette system. This technique was developed by London-based Knox Bhavan in partnership with modular manufacturer BlokBuild and engineers Price & Myers. The aim was to make a sustainable home that ‘will withstand the site’s predicted increased flood risk for the next 100 years, presenting a viable design solution for building on sites susceptible to flooding’, explain the team.
When we met outdoor furniture manufacturer Vestre’s then-CEO (and current Minister of Trade and Industry of Norway) Jan Christian Vestre about a year ago, he enthusiastically took us through his plans to create The Plus, ’the world’s most sustainable factory’. Now, thanks to his efforts and with a design courtesy of Bjarke Ingels Group (BIG), the building site in the middle of a Norwegian forest we visited in 2021 is now a fully fledged production facility – and so much more. The Plus opens this week in Norway’s Magnor, inviting employees, clients and visitors to experience its sustainable architecture. ‘The Plus is a factory for the people! It is a project we have put an enormous amount of soul and energy into. This is an important day for us, but also for the Norwegian mainland industry and the Scandinavian export cooperation,’ says Stefan Tjust, current CEO of Vestre.
asa Azul may be the latest in a long line of residential masterpieces by Marcio Kogan and his partners at Studio MK27, but it is unique among its distinguished cohort for its site, a rare parcel within the protected Atlantic Forest that has shaped this project in every way. Located in Guarujá, Brazil, in the state of São Paulo, with the stunning Iporanga Beach and Atlantic Ocean a mere 500m away, Casa Azul is a study in sustainable architecture and development and contemporary Brazilian architecture. Understandably, the local municipality was strict about its construction. It took nearly two years to secure the required environmental agency approvals, which mandated a 2m-wide protective bubble beyond the footprint of the home to shield the forest from building activity. Officials were on site daily to inspect the impact of the project on the surrounding flora, but Kogan, Diana Radomysler (he co-heads the studio with her, Renata Furlanetto, Suzana Glogowski and Mariana Simas) and their co-designer Samanta Cafardo were more than happy to comply with strict environmental oversight, and to go even further.
The Observatory at Wardian is an exclusive botanically-inspired sky bar and lounge on the 53rd floor of the East London high rise residential development. The scheme emphasises living among greenery and the role of plants, and blending indoors and outdoors to wellbeing ‘It has been a pleasure to work with EcoWorld Ballymore on Wardian and to see our joint vision brought to life. A central idea behind this collaboration was to connect people with nature and outside space; Wardian’s strikingly clear architectural expression, carried through into the interior spaces as one continuous piece of design, allows residents and visitors to enjoy a series of dramatic and immersive spaces with abundant views of nature and the surrounding townscape. This is especially so in the 53rd floor Observatory, which delivers a powerful first impression, a sense of discovery and grand scale that are central to Wardian’s appeal, realising the bold vision we shared with EcoWorld Ballymore for this unique scheme.’ says Will Poole, of the space’s authors, Glenn Howells Architects.
Indian architecture practice Earthitects has transformed its own office in Bengaluru into an exemplary eco-friendly space. ‘Using local labour to fabricate almost every single piece of furniture in-house, we have crafted tables, seating, workstations and lighting–all from wood which no one else wanted,’ the architects explain. The design revolves around nature and an overall organic feel, built with principles such as in mind. Eucalyptus poles and jute blend with a range of wood grains and textures. Seen here, is the meet-and-greet space - a mulitfunctional space for various formal and informal meetings featuring a bespoke hanging table.
UCL Student Centre
The Student Centre sits at the heart of UCL’s Bloomsbury Campus in central London. Designed by Nicholas Hare Architects, the project not only creates a warm, functional space for student to use for meeting, eating or working - it also has some strong eco credentials too, without compromising on style. The building, which transforms a back of house gap site, has achieved exemplary sustainability standards including BREEAM Outstanding. Inside, key components include 1,000 study spaces for students, a Student Enquiries Centre, a café, and spaces for quiet contemplation or prayer.
The Kirk Ella Conservation area is a large, verdant suburb situated in East Riding of Yorkshire, on the western outskirts of Kingston upon Hull. Its close proximity to a city centre along with its green natural environment and architectural interest (it combines well preserved samples of 18th, 19th and 20th century architecture) make it a desirable place to live; and this is exactly where a local couple chose to build their new home. The result is Gowland House, a generous, contemporary Yorkshire house by Grimsby-based ID Architecture. The residence replaced a small, existing bungalow on site. The clients’ main request was that the new space should be large enough to accomodate their extended family - children and grandchildren - for extensive stayovers during holidays and weekend breaks. As a result, the architects created a sprawling villa that wraps in an L-shape around a paved terrace with swimming pool, and spans two levels, in order to accomodate all the bedrooms and a variety of living spaces. The sizeable home - at some 600 sq m - also includes a home gym, pantry, utility spaces and a boot room, providing all-mod-cons for the residents. Additionally, there is provision for the infrastructure for sustainable technologies, including Tesla battery wall, solar PV panels and air source heat pumps.
Rain Harvest Home
About two hours west of Mexico City in the region of Temascaltepec, a recently completed home for an architect and his family is giving a new face to water conservancy. Comprised of three small structures that include a main residence, an art studio and a bath house, the Rain Harvest Home integrates rainwater-harvest architecture – an uncommon practice despite the region having abundant rainfall. Designed by the home’s owner Javier Sanchez of JSa architects and Robert Hutchison of Robert Hutchison Architecture, the concept behind Rain Harvest Home is rooted in the unique qualities of where it’s located – within Reserva el Peñón, a landscape-driven development that has achieved water self-sufficiency for a community of 80 families in 450 acres of a nature reserve.
Ecology Green Farm
At the end of a powdery orange dirt track, a two-hour drive from Lagos in the village of Ikise, in south-western Nigeria, sits an earth brick barn house. The jewel in the crown of Ecology Green Farm, it’s a new artists’ residency space established by British-Nigerian artist Yinka Shonibare. Set on the highest point of the farm’s 54 acres of land, surrounded by panoramic views of lush forest, grassland and bush, the building’s laterite shell radiates a warm golden glow in the late morning sun. Myriad butterflies settle and take flight, while the hum of insects, rustling grass and birdsong forms the soundtrack to this country retreat. The barn house accommodates a studio and living quarters for the participants of the artists-in-residence programme, which launches this spring, offering the opportunity to live and work on site over a three-month period. Artists also have the option of spending the residency at an alternative location in Lagos, and both sites are run by the Nigeria-based Guest Artists Space (GAS) Foundation, a sister organisation to the Yinka Shonibare Foundation, led by director Belinda Holden. ‘We should all be closer to nature,’ says Shonibare, as he reflects on Ecology Green Farm’s remote location. ‘It’s an excellent environment for artists to be inspired and work, and to have some quiet.’ Additional writing: Idjeoma Ndukwe
Addresssing sustainability and food production, the rooftop greenhouse of Agrotopia is the brainchild of Belgian studio META architectuurbureau and Dutch practice van Bergen Kolpa Architecten. This is the largest public building dedicated to urban food production in Europe, the architects claim, and it was a commission from the Flemish research institute for agriculture and horticulture, Inagro, and REO Veiling. The design, located in the Beglian city of Roeselare, boasts an innovative water recuperation system and reuses urban waste heat. ’Together with the clients, Inagro and REO Veiling, we have realised an ambitious building with numerous innovations. A single building featuring different climate zones, sustainable and economical use of space, research into leafy vegetables and fruit vegetables in the city, opening up the rooftop to a public function, circular use of space and energy, to name but a few,’ says Jago van Bergen of van Bergen Kolpa Architects.
A prototype solar greenhouse for food and energy production in cities has been built in the outskirts of Barcelona. The project ’proposes a space for self-sufficient cultivation as a solution to producing food and energy in cities and advance towards the zero-emissions city model as proposed by the EU for 2050,’ explain its creators, and can be adapted and scaled up or down to fit empty urban plots, gardens or rooftops. The wooden structure, which was developed by a team of students and researchers of the Masters programme in Advanced Ecological Buildings and Biocities (MAEBB) of the Institute for Advanced Architecture of Catalonia, sits lightly on the ground in the Natural Park of Collserola. The design employes solar energy, sustainable materials and advanced cultivation technology to address a number of contemporary issues, including climate change and food production.
York St John University’s new Creative Centre
Tate + Co Architects and York St John University have just launched the institution’s new Creative Centre; a new home for the music and computer science courses. Specialist spaces for performance, creative writing and media production students all sit within this elegant, low-energy building whose eco credentials span from operational to embodied carbon terms. A substantial timber frame and simple climate control are among the environmentally friendly strategies the East London architects adopted in their design, which uses timber to wrap many of its spaces in warmth and organic textures. ’The Creative Centre at YSJU demonstrates that you can provide students with state-of-the-art facilities without sacrificing environmental sustainability. It was important to plug these aspirations into the design from the outset and this is the reason the University chose our practice. They recognised that the only future for the campus is one that puts the needs of students first, while simultaneously supporting greater sustainable initiatives,’ says studio director Jerry Tate.
Henley Hall, one of American architecture studio Kieran Timberlake’s latest education work is a striking new home for UC Santa Barbara’s Institute for Energy Efficiency; it’s also a project that has already achieved a coveted LEED Platinum certification, and won a 2021 American Architecture Award, among other accolades. “We are honored to work with UC Santa Barbara to make Henley Hall the ideal campus
home for the IEE,” said Jason Smith, partner at KieranTimberlake. “Our expertise in innovative, sustainable design aligns perfectly with their forward-thinking mission to create new technologies in pursuit of an energy efficient future. These shared values contributed to a forward-thinking and vibrant environment for science and collaboration.”
A family home located in the UK’s High Weald area of outstanding natural beauty takes inspiration from its environment, with a focus on natural materials and sustainability. Woodlands, in the East Sussex village of Wadhurst, rethinks the 1920s chalet bungalow originally on the site, building on the previously developed land of the original house. The semi-natural grass already present – with its potential for biodiversity enhancement – becomes a living part of the new development. The five-bedroom home by Williams Griffiths Architects comprises an open layout, with interconnected living spaces offering extensive opportunities for a family to work and live in the space. The design considers the growing family’s immediate needs, with a choice of main and secondary entrances and a second kitchen presenting alternative living options for the future.

Approaching Villa Pirogovo from afar, a series of catenary dome structures appear to be peeking out from the ground. Made of concrete and glass, these are the dramatic bedrooms at Dutch architect Erick van Egeraat’s latest residential offering in Russia. When walking towards the main entrance, the villa fully reveals itself in all its expressive concrete glory that mixes angular geometries with those distinctive sleeping pods, all nestled into the dense pine tree forest along the banks of the Klyazma River in the Russian countryside. The commission came from a private client who was after a holiday home that would work equally well for both the pleasant summer and the harsh winter conditions of the region. The team at van Egeraat’s architecture studio focused on creating an exuberant composition that offers 21st-century design and all mod cons, while absorbing the natural beauty of the surroundings, allowing the views to take centre stage at almost every room through swathes of glazing, terraces and balconies.
If the pandemic has got you dreaming of the green countryside, secluded cabins and a poised, neat minimalist life, The Bide might be just the thing for you. This architectural Dorset cabin is a labour of love of a pair of design enthusiasts – one an architect, of London-based studio LAMA, and the other working for Nordic design brand Åben. The pair joined forces and brought together their expertise to build, almost entirely by hand during one of the recent lockdowns, this charming getaway – a rural escape with an architectural twist. The cabin was designed for themselves, as a private retreat, which can also be used on occasion as a rental. Handling the design, product sourcing and construction together, the couple ensured that their project employed principles of sustainable architecture, such as using local materials and eco-friendly building techniques. For example, The Bide is designed using the WikiHouse system, with a wooden frame cut by CNC and bolted together by hand. Low-carbon materials used include sheep’s wool and woodfibre insulation. There is a Separett waterless toilet from Sweden, a decentralised MVHR system, and a Nebia vaporised water shower that ‘uses 40 per cent less water than a regular shower’.
Kashef Chowdhury/Urbana’s Friendship Hospital in Bangladesh has scooped the prestigious RIBA International Prize 2021. The institute’s award casts its net wide, celebrating outstanding, international works that ‘demonstrate design excellence and social impact’. The winning project, led by NGO Friendship, does just that. Not only does it provide functional and considered architectural space for important health services to the local communities of Satkhira in southern Bangladesh, but it also employs sustainable architecture to do so.
Shenzhen Rural Commercial Bank Headquarters
SOM’s latest high rise offering, the Shenzhen Rural Commercial Bank Headquarters in China, employs clever design and biophyllic principles to help the structure adapt to its tropical climate and wider environment. ’The tower’s façade is defined by an external diagrid, which serves as both the building’s structure as well as an important solar shading element. At its base, the diagrid widens to create framed openings and views to the surrounding park and South China Sea, a short walk from the building,’ explain the architects. This diagrid, which is similar to an exosceleton, also helps define the building’s overall looks. Inside, the interior draws on Feng Shui principles, blending air, water and earth into the design. The tower is LEED Platinum and is targeting China Green Star certification.
The Mercury Store
A start-up space for theatre artists, from stage directors to choreographers and devisers, The Mercury Store is a new cultural hub in New York City, created by CO Adaptive Architecture. The space was designed to serve a variety of purposes, including residencies, studio and co-working space, community and funding activities. The architects used CLT - the first documented use in town of this carbon negative material - to transform the 12,700 sq ft former metal foundry, retrofitting it and reusing and repurposing many of its existing elements. ’This is the first project in New York City to use mass timber to transform an adaptive reuse building, and we hope it will lead by example; exemplifying the capacity of mass timber to simultaneously reduce our embodied carbon and reinvigorate our aging building stock,’ says CO Adaptive co-principal Ruth Mandl.
Haus on the Ridge
The Brownie, the series of photographic cameras made by Eastman Kodak in the early 20th century, inspired Haus on the Ridge, reveals the architect and owner of this Kent house, TP Bennett principal director Doug Smith. Nestled in the green English countryside, the home, created with project architect Sam Clarke, is not only a striking family abode, but it’s also conceived according to the principles of sustainable architecture and follows strict Passivhaus standards. ‘As architects we all dream of designing and building our own home. Having taken an early interest in the Passivhaus concept, this project gave me the perfect opportunity to challenge myself and Sam, bringing together clean, minimalist, exceptional design with Passivhaus sustainability credentials,’ says Smith. His wife, Wendy, adds: ‘The Passivhaus provisions give a level of comfort to the design standard and more. The simple, predominantly open-plan living space, with its incredible interaction with the outside space and the rural setting, makes living in the house a joy.’
PolyRoom by Cutwork x Bouygues Immobilier
French developer Bouygues Immobilier has joined forces with architects Cutwork to launch an innovative new building model. Bringing together Japanese simplicity with LEGO-like assembly, the concept centres on a prefabricated, modular unit: PolyRoom. A prototype unit has already been built, and the team aims to launch the first development created using the PolyRoom concept soon, with a view for completion in 2023 in Bordeaux. The structure will herald a new living brand for Bouygues Immobilier - one that is green, functional and which is ’carefully designed to activate biodiversity and local ecologies’ on its site. Cutwork co-founder and architect, French-Japanese Antonin Yuji Maeno ’took inspiration from the Japanese concept washitsu 和室わしつ. A washitsu is a central room in traditional Japanese homes. It has no predefined or single dedicated purpose, but rather is an adaptive space that can take any shape to meet inhabitants’ changing everyday needs.’
Dwelling Unit for Musicians by Automated Architecture (AUAR)
Created for a family of musicians - a cellist and double bassist - this sustainable home extension was designed by emerging design firm Automated Architecture, and it is the studio’s very first dwelling. The clients were in need of space to use as an office and rehearsal studio. The design team obliged and composed a robot-fabricated, modular system made from timber elements, which extends into the existing home’s rear garden. The concept is easy and fast to assemble, reducing construction costs and pollution, and it is replicable since it can adapt to different sites and needs. The scheme combines a sustainable architecture approach with high tech fabrication methods, which makes it all the more practical, the team at AUAR explains. ’For AUAR, people are central to automation. This starts with design. Our homes are not standard, one-size-fits-all spaces, but can be tailored and customized for every unique client, for each specific plot of land. As we use intelligent robotics and automation, it doesn’t cost anything more to make a different home each time," says the studio’s chief technology officer Gilles Retsin.
Harvard Science and Engineering Complex by Behnisch Architekten
Harvard’s new Science and Engineering Complex (SEC) has sustainable architecture at its heart. The eight-level, 544,000 sq ft structure was designed by architecture studio Behnisch Architekten, who prioritised functionality and environmentally friendly strategies in their design. As a result, the building, which includes energy-conscious HVAC and lighting systems, and planted roof terraces, has received a coveted LEED Platinum and Living Building Challenge certification. The generous structure spans three volumes housing classrooms, fabrication studios, teaching labs and amenity spaces, but is elegantly broken up by green areas and openings so that it allows its users space to breathe and lets nature in.
Wanchai Community Green Station by BREAD Studio
The Wanchai Community Green Station in Hong Kong is ready to open. Designed by BREAD Studio, the project was part of The Hong Kong Environment Protection Department’s efforts to create a more sustainable recycling network - and this station is one of ten brand new Recycling Stations in this initiative. Made of steel, clad in wood and with a GRP double curved secondary beam, this new piece of industrial infrastructure features impressive geometries and an eye-catching, sweeping shape. As well as fulfilling its duties within the realm of sustainability, the structure also features a green square which will be accessible and open to all, so the local community can use it freely as an open air point to sit and gather.
The Arc at Green Scool by Ibuku
The Green School in Bali is known for its finely tuned programme that follows children from early years through to secondary education, infused with a focus on creativity, the arts and ecological responsibility. Founded by John and Cynthia Hardy in 2006 and built around the principles of sustainable architecture, the school is a unique take on education; and now, it can also boast a brand new structure in its midst. The Arc, designed by local design and architecture studio Ibuku, headed by Elora Hardy, has recently been completed, offering a fresh visual shorthand for education architecture and the school’s green identity through its pioneering, green bamboo roof. The project was designed to host a wellness space and gymnasium for the school campus. Whimsical but sturdy, beautifully undulating as well as light and dynamic – almost like the bamboo version of a boat’s billowing sails in the wind – the roof is thin and balanced, and feels organic and close to nature. The trick was marrying traditional, age-old techniques for building with bamboo, and new technologies, Hardy, explains.
Falcon House by Koto
British-based prefabrication specialist Koto has been hard at work developing modular home design, from compact work cabins to agile mini abodes, since its inception in 2017. The forward-thinking company, founded by couple Johnathon and Zoë Little and architect Theo Dales, has completed a range of minimalist cabins, such as its off-the-grid sauna in Ireland, all infused with Scandinavian style and sustainable architecture principles. But the energetic brand is not resting on its laurels, taking its minimalist Nordic architecture aesthetic to the larger scale and launching its first ever, two-storey modular design – meet Falcon House.
Haus im Obstgarten by Firm Architekten
Offering a contemporary take on the traditional Austrian farmhouses of the region, Haus im Obstgarten is the brainchild of local studio Firm Architekten. The beautifully poised house – a small, minimalist timber tower – sits on a slope in the village of Frastanz-Gampelün, on a plot owned by the client and their family for decades. The new structure replaces an old stable building nestled on a hillside between two farmhouses. The minimalist architecture approach evident in Haus im Obstgarten’s exterior continues inside, where the only decoration is provided by structural details and the tactile nature of the wood – making this project a contemporary ode to timber construction. Embellishment is kept to a minimum throughout, contrasting with the regional farmhouses’ more ornate interior styles, the architects explain.
The Wood Hotel by Elite by White Architects
This striking building boasts to be one of the world’s tallest biuldings. Set in Skellefteå, within the idyllic natural scenery of Swedish Lapland, the scheme is a hotel, aptly named The Wood Hotel by Elite and designed by White Architects. Combining the trusted, natural material and high end engineering innovation, the building also aims to be carbon dioxide neutral within its first five years. ‘Our concept is very inspired by the Swedish North’s unique nature and its legacy within forestry, but also Skellefteå’s modern position as an epicenter for progressive, green-tech engineering. We want to create memorable experiences and evoke a sense of hopefulness of what the future could hold, encouraging our guests to explore new ideas - be it inside of their room or beyond,’ says Caroline Chakraborty, the family-owned business’s partner and board member.
‘The Sustainable Glasgow Landing’ at COP26 by New Practice
What used to be a petrol station in the late 20th century, was just a vacant site on the Broomielaw for a while before being transformed into a temporary, dedicated venue for events during the COP26 conference in Glasgow. The project was led by a mutli-disciplinary creative team led by Glasgow based architects New Practice, in collaboration with Inhouse, and promises to offer space for a rich programme of events, from performances to knowledge sharing, exploring sustainable architecture for locals and visitors alike.
‘Urban Sequoia’ model by SOM
Architecture and the built environment have received scant attention in the coverage of COP26, the UN Climate Change Conference. It’s an obvious blind spot given that the building sector currently generates 40 per cent of all global carbon emissions and that massive population growth and increased urbanisation mean there’s a lot more building to be done. It is predicted that another 230 billion square metres of new building stock will be needed by 2060. Of course, many architects have developed innovative ways to reduce that carbon debt, both in construction and during a building’s lifetime, through sustainable architecture. Now one of the industry’s giants, Skidmore, Owings & Merrill (SOM), is unveiling a model for carbon-negative architecture – meet the ‘Urban Sequoia’. Additional writing: Nick Compton
The Pavilion at Endeavour Square by ACME
Stratford just got a new meeting place. The Pavilion at Endeavour Square has just been unveiled to a design by ACME, bringing sustainable architecture, fun design and a touch of placemaking to this part of east London. The London architecture studio’s director Friedrich Ludewig started off designing with a seemingly blank slate site – an open and as yet undeveloped part of Stratford’s International Quarter that sits just outside the borders of the Westfield complex and next to the large bridge that takes visitors through to the Queen Elizabeth Olympic Park, the Aquatics Centre and the West Ham’s London Stadium beyond. Surrounded at the moment by construction, newly completed office towers and enough rail tracks to make a train spotter happy, the site was in need of a purpose and a focal point – something fun and engaging, welcoming, useful and strong enough to act as a landmark for its corner of this still-growing London neighbourhood.
FarmED by Tim Tasker Architects
This Cotswolds farming centre has been designed to be clever and sustainable by Tim Tasker Architects. FarmED at Honeydale Farm ‘works to educate communities on the role of regenerative farming in combating climate change, a mission that extends to the architectural aspiration and execution of three highly efficient mixed-use buildings on site.’ The U-shaped scheme is made up of three, minimalist, timber barn-like structures - a nod to the local vernacular typologies of the region. Extensive research on embodied carbon and careful material and construction method selection means this is a particularly eco-friendly complex.
REWE Market of the Future by ACME
ACME has created a new model for a farmer’s market for the city of Wiesbaden-Erbenheim in Germany. The project experiments with timber construction, offering a ‘prototype for a new adaptable and sustainable market concept, able to fit any site typology,’ say the architects. The design is capticating yet simple, using standard wood elements, which were readily available locally and were assembled with simple screw connections. It is ‘an environment which re-establishes our human connection to locally sourced food,’ the architects say.
HiLo by ETHZurich
Based on important ETHZurich research on architecture and sustainability, this is HiLo - the latest addition to Empa (Swiss Federal Laboratories for Materials Science and Technology) and Eawag’s (Swiss Federal Institute of Aquatic Science and Technology) NEST research building in Duebendorf, Switzerland. A team effort between scientists led by Philippe Block, Professor of Architecture and Structures, and Arno Schlueter, Professor of Architecture and Building Systems together with industrial partners, ‘explored how lightweight structures and efficient construction methods can be combined with intelligent and adaptive building systems to reduce both embodied and operational emissions in the construction and building industry.’
Ilulissat Icefjord Centre by Dorte Mandrup
The spectacular Ilulissat Icefjord Centre sits on a craggy seashore on the edge of the UNESCO-protected Greenland wilderness. Designed by Danish architect Dorte Mandrup, the scheme, some 250 km north of the Arctic Circle, feels at one with its landscape. Its purpose is strongly connected to nature too, as it was conceived to highlight the ‘dramatic consequences of climate change on this remarkable landscape.’ A year-round visitor centre, as well as place to meet for locals, the building snakes around the hilly terrain telling, through its displays, activities and presence, the story of ice, nature and humankind. ‘The Icefjord Centre offers a refuge in the dramatic landscape and aims to become a natural gathering point from which you can experience the infinite, non-human scale of the Arctic wilderness, the transition between darkness and light, the midnight sun, and the Northern lights dancing across the sky,’ says Mandrup.
Casa Numa by Red Arquitectos
A home designed to use as a personal retreat for the client, as well as a holiday rental, Casa Numa is the brainchild of Red Arquitectos. Nestled in a fairly moderst spot in Holbox Island, Quintana Roo in Mexico, the building is almost entirely created in coconut palm wood and is supported by sapote tree piles that come from the region’s jungle. This way, the project has a light impact on its sandy terrain and remains respectful to its surroundings, the architects explain. ‘The palm is considered the tree of life, since human existence could be sustained with everything that comes from it. It is a natural insulating material that offers a pleasant climate due to its thermal properties, allowing less energy consumption and natural cooling,’ says the team. The structure becomes a fine example of wood architecture and its main shell was created in a mere three months.
The Hilda Solis Care First Village by CRATE Modular
This LA-based project is dedicated to homelessness services and includes 232 units, a mess hall, and an administrative building. Created by CRATE Modular and named the The Hilda Solis Care First Village, the scheme was made almost entirely out of recycled shipping containers - each of which contains two sleeping pods. Looking sleek and modern, while keeping costs and construction impact to a minimum this clever project works hard for its money - prioritizing modular, sustainable architecture and building.
Bundeena House by Tribe Studio Architects
Taking its cues from modest fishing village cottages, this home is a prototype of a sustainable retreat cabin by Tribe Studio Architects. Set in Sydney’s seaside community of Bundeena, the project is cost-effective, environmentally-aware and supportive of local trades, explains the design team. ‘We could have had glorious views from a second storey, however we felt that reinforcing the local vernacular of single storey timber cottages was important, and that an introspective garden diagram was preferable to outward looking in this context,’ says studio director Hannah Tribe. ‘This house is an attempt to achieve a high level of architectural and sustainable outcomes at a low cost. It is an experiment in delivering a more thoughtful kit home.’
House Under Shadows by ZED Lab
Created by Delhi based architects Zed Lab, this expansive home is a near net-zero residential structure. Called House Under Shadows for its perforated external shading that creates mesmerising shadow-and-light plays on its large terraces, the home was ‘an architectural response to the extreme weather in North India,’ explain the architects. ‘[The structure] achieves reduced solar direct and diffused radiation by 65% through digital modelling using parametrics and passive design strategies,’ says the team. The architectural approach combines elements from the local vernacular and modern, sleek style, while enabling natural ventilation and daylight.
AirBubble playground by ecoLogicStudio
A strange circular structure has appeared in a green architectural garden at the centre of Warsaw, Poland, outside city’s the Copernicus Science Centre. This is the world’s first biotechnological playground integrating air-purifying micro-algae cultures, say its architects, London-based architecture studio ecoLogicStudio, led by Claudia Pasquero and Marco Poletto. The open air structure creates a purified microclimate where children can play. Merging biotechnology with archtiecture, the structure comes accompanied by a temporary exhibition on site. ‘There is untapped value in bringing the bio-intelligence of natural systems into cities, turning buildings into living machines that produce energy, store CO2 and clean the air. To achieve this, we need to think about the living world as a part of the current digital revolution: nature becomes part of a new bio-smart infrastructure,’ says Poletto.
House with Three Pavilions by Grounded
Combining a contemporary design approach with sustainable architecture, this home in a rural location in Goa was created by GROUNDED, the Indian architecture studio led by Anjali Mangalgiri. ‘The house attempts to leave a minimal or zero-impact on the functioning natural ecological cycles at the site that pre-date the new construction,’ she says. ‘It contributes positively by fostering biodiversity and recharging the underground water table.’ Created as a second home, the structure occupies a small fraction of its wider site. Natural materials the connect the building to its surroundngs play a key role in the design, and include terracota tiles, teak wood and a natural Indian stone in a blue-green colour.
Timber House by Gbolade Design Studio
A 1960s home in Chislehurst, Kent, in the UK, has been transformed with a dramatic extension by London based Gbolade Design Studio. Headed by Tara Gbolade, the architecture practice created a bold new design, Timber House, which goes beyond pure aesthetics to enhance the building’s sustainability credentials and the architecture’s overall functionality. Clad in stylish dark timber and featuring a defining pitched roof, the house results from a commission to refurbish and extend a family home. The new structure may have changed the home’s spatial experience but it doesn’t feel alien within its context; in fact, its new shapes and size are proportionate, respecting its surroundings and the existing building. Inside, however, the space has been significantly upgraded, with the addition creating soaring double-height ceilings, angular feature interiors (which reflect the original and new pitched roofs), and an open-plan arrangement that encourages interaction and flexiblity for the residents.
Torvbråten Primary School by Link Arkitektur
This school in a rural spot within the Norwegian forest has just been completed to a design by locally based architecture studio Link Arkitektur. Guided by sustainability principles, theTorvbråten Primary School has become Norway’s second school to achieve the highly-regarded Nordic Swan Eco-label for best environmental practice. The building’s eye-catching curves have been clad with Kebony wood, the sustainably modified, durable timber. The result is not only a boost to the structure’s eco-credentials, but a highlight in its overall striking visual aesthetic too. Additionally, the school has been designed according to the passive house standards and is equipped with 800 solar cells and energy wells (geothermal heating). Now, it caters to some 470 students and 46 permanent members of staff between its classes, offices and multi-purpose hall.
Lemvig Klimatorium by 3XN
The town of Lemvig, on Denmark’s west coast, may be small and far away from the capital, but it aspires to play a vital role in the nation’s efforts to fight climate change. Aggressive storms and rising sea levels have heightened the risk of flooding, prompting the town to redevelop an old industrial area on its waterfront: adding a flood wall, installing a new promenade, spaces for new businesses, and most importantly, an international climate change centre, Klimatorium, to offer a meeting point for residents and tourists, educate the public about the climate emergency, and support Denmark’s role as an exporter of climate solutions. Commissioned by the town council to create this centrepiece, architects 3XN devised a two-storey building that makes a visual statement while keeping to a limited budget and environmental footprint. The landmark feature is a wave-shaped wooden pocket, caving into the southern façade of the building and facing a skate park by the Copenhagen-based studio Effekt, completed in 2013. Clad in local pine, the wave is smoothly contoured for the most part, but tiered at the base to provide seating. As Jan Ammundsen, senior partner and head of design at 3XN explains, the initial intention was simple: to create a sheltered spot that would be available to both the building’s users and passers-by, bathed in sunlight but protected from westerly winds across the water. ‘We are hoping to create a small possibility for them to sit, enjoy the moment, and speak to each other,’ says Ammundsen. ‘It’s a way for the building to give a little bit back to the town.’
Modular initiative by MiTek and Danny Forster & Architecture (DF&A)
There’s a new kid on the prefab block; welcome the joint modular initiative of provider of innovative construction-based software, services, and engineered building solutions MiTek and Danny Forster & Architecture (DF&A). The scheme, which has been created by the digital systems specialist (who is owned by multinational conglomerate Berkshire Hathaway) and the New York based architecture firm, was conceived to champion prefabrication and flexible, sustainable building. Central to the initiative is the creation of a Modular Activation Platform (MAP), which will help simplify working with and designing modular buildings. ‘This will democratize modular – which means revolutionising the building industry,’ says DF&A principal Danny Forster. ‘Modular has such clear advantages, but for your average commercial builder, the risks are too high and the learning curve is too steep. Our activation platform will change that.’
‘Structure’ by Better Shelter
Social enterprise Better Shelter creates emergency and temporary sustainable housing for communities displaced by the climate crisis. With pilot sites for its shelters, called ‘Structure’, currently in India, Afghanistan, Tajikistan, and Rwanda, its short-term solutions provide a sustainable response to the climate crisis that has left millions homeless. The company, based in Stockholm, Sweden, delivers modular homes in flat packages that can be speedily assembled without the need for tools or electricity. Equipped with a lockable door and a solar-powered lamp, they are created using materials local to their site, such as bamboo, timber and wattle and daub, and have the potential to be adapted by their occupiers for longer use.
Khor Kalba Turtle and Wildlife Sanctuary by Hopkins Architects
This cluster of low, round buildings on the edge of the water in the Gulf region is the brand new Khor Kalba Turtle and Wildlife Sanctuary facility at the Kalba mangrove reserve in the UAE. Designed by Hopkins Architects, the project is an important sanctuary for rehabilitating turtles and nurturing endangered birds in this richly biodiverse part of the world. The project was commissioned by Sharjah’s Environmental Protected Areas Authority (EPAA). It encompasses education and visitor facilities too, helping to raise awareness of its important work in its field. ’Designing for a site like this is an incredible opportunity,’ says Hopkins’ principal Simon Fraser. ‘The pioneering circular forms we designed for the Buhais Geological Museum, are also perfect for this rich ecological location as they touch the ground lightly. We have adapted them using soft scalloped precast cladding made from discarded shells found in the local area which responds to the marine environment and which softens the external appearance of the project to harmonise with its surroundings.’
Kaj micro-hotel by Barbara von Haffner and Toke Larsen
The Copenhagen architecture scene is full of must-sees – from modernist masterpieces to contemporary marvels, such as OMA’s BLOX. Yet there are also some smaller gems that bring a sense of architectural experimentation to the everyday for the discerning visitor – such is Kaj, the town’s latest sustainable micro-hotel, which has been designed as a boutique, one-room boathouse you can rent. It all started when owners and partners in work and life Barbara von Haffner and Toke Larsen spotted a gap in the market. With the help of architect Karl Smith Meyer, they decided to put a plan into action. ‘We have often been contacted by people who wanted to rent our houseboat or asked what it is like to live on it,’ they say. ‘The idea for KAJ Hotel arose in the wake of these questions, which were almost impossible to answer unequivocally, as the experience varies depending on wind and weather conditions, as well as what time of day – or year – one stays there. One has to try it out for one self – and every moment has its own charm.’ Now, set on Copenhagen harbour and built literally on the water, Kaj is created primarily in recycled wood. Its structure was partially prefabricated (on the deck of the couple’s houseboat) and craned directly into the site. Von Haffner also leads Undercover Copenhagen, a company specialising in recycled and sustainable fabrics, while the couple’s own home was created using environmentally friendly ways, so looking at this project from an eco-friendly angle came naturally to the pair.
Cowboy Modern Desert Eco-Retreat by Jeremy Levine
Nestled within desert flora and rocky hills, the Cowboy Modern Desert Eco-Retreat is architect Jeremy Levine’s personal getaway – a stylish and entirely off-grid property with no water, sewer, or mobile service. Dramatic as this might seem, this sustainable home is as visually and technologically sophisticated as they come, featuring sleek contemporary forms and eco-friendly systems. Set in Southern California’s Mojave Desert near Pioneertown and Joshua Tree National Park, the two-bedroom residence is surrounded by mesas and low desert vegetation. Inspired by this beautiful natural landscape, the architect composed a home that acts as a flagship for sustainable living, both in terms of its building methods and its connection with its surroundings. Large openings, locally reclaimed weathered lumber for all interior and exterior wood, and a roof pitch that echoes the context’s angles, mean this retreat is very much in sync with its locale.
Tambacounda Hospital extension by Manuel Herz
A brick extension to the Tambacounda hospital in Senegal by Switzerland-based architect Manuel Herz is a true project of collaboration, rooted to the local community. ‘I received an invitation from the Albers Foundation and Le Korsa to take part in the competition for a new maternity and paediatric unit at Tambacounda Hospital,’ explains Herz. ‘I put a lot of thought into it and responded that the best approach was not to create a so-called architectural design “solution”. Instead, our entry took the form of a proposal embedded in research and collaboration; not a building, but a suggestion of how to approach the project.’ Herz’ considered thinking won the competition. The design is defined by the striking geometric bricks that make up the main façade. ‘I undertook a lot of research into the region for my book, African Modernism, the architect explains. ‘I also looked at responses to climate and elements like brise soleils, which became quite prevalent in the 1960s and 1970s.’ The porous veil of bricks is a relatively common façade treatment in the east of Senegal, with the bricks themselves typically made on site. ‘What I brought to the project was the specific shape and geometry of the bricks,’ Herz says. ‘With every building I design I try to come to learn something new and try out new things.’
The Voxel by the Institute of Advanced Architecture of Catalonia
The Voxel is a unique prototype designed by students and researchers of the Master in Advanced Ecological Buildings and Biocities (MAEBB) of the Institute of Advanced Architecture of Catalonia (IAAC) under the direction of Daniel Ibáñez and Vicente Guallart. It was created as ‘an advanced ecological building’ made of natural KM.0 materials and industrialized techniques within the natural park of Collserola in Barcelona, Spain. Part of the project is researching wood and its structural and thermal abilities, as well as its capacity to store CO2 in buildings. Using wood sourced through sustainable forest management, the team experimented with the Japanese Shou Sugi Ban charred wood insulation technique to protect the material and structure in an environmentally friendly way.
SLAK Campus by Kéré Architecture
Turkana County in Kenya is a large expanse of beautiful yet arid land of low bushes and occasional trees, home to Lake Turkana, the country’s largest landlocked body of water and the biggest desert lake in the world. Termite mounds, buzzing with activity and up to several metres high, are dotted around the region’s gently undulating landscape. It was these tall structures that first caught the eye of Berlin-based architect Francis Kéré when he started researching the area for one of his latest commissions – a sustainable education campus on the lake’s banks. Celebrating the local context and the termite mounds, tall towers support natural ventilation ‘by extracting warm air upwards, while fresh air is introduced through specially designed low-level openings’, says Kéré. Electricity is produced on site, using solar panels.
TECLA by Mario Cucinella Architects with WASP
Mario Cucinella Architects has built the world’s very first 3D printed house made entirely from raw earth. Named ‘Tecla’, and built in collaboration with specialists in the field WASP, the structure demonstrates the point where natural materials meet technology and has just been unveiled in Italy’s Massa Lombarda region, near the city of Ravenna. ‘Adopted from one of Italo Calvino’s Imaginary Cities, one that is forever taking shape, the name ‘Tecla’ evokes the strong link between past and future combining the materiality and spirit of timeless ancient dwellings with the 21st-century world of high-tech production,’ say the architects.
Casona Sforza by Alberto Kalach
Known for its sandy beaches, green setting and surfing spots, Mexico’s Puerto Escondido now has one more card up its leafy sleeve: a new hotel with strong sustainability credentials, designed by acclaimed Mexican architect Alberto Kalach. Casona Sforza, conceived by the entrepreneur Ezequiel Ayarza Sforza, has just opened its doors and combines an eco-approach with striking architecture and state-of-the-art hospitality and interiors. Set in La Barra de Colotepec, facing Mexico’s Pacific Coast, the hotel’s distinctive form represents its strong ‘ecological commitment’, says the team. Composed of a series of round-roofed brick volumes, the flowing structure feels natural and uses the country’s ancient techniques of brickwork, arch and vault building. This approach not only feels appropriate to the project’s context and the region’s history, but also makes the most of the fine anti-seismic properties of the vaulted shapes.
Haycroft Gardens by Sarah Wigglesworth Architects
Engulfed in a wild, leafy garden, a new multigenerational home in north London is designed to be functional and inclusive. Haycroft Gardens, created by architect Sarah Wigglesworth and her team, may appear humble, but it takes sustainable architecture to the next level. Commissioned to work on an infill site in Kensal Green, Wigglesworth was invited to create a single-level, three-bedroom home that would accommodate the needs of a young family and an elderly parent within the same domestic scheme. ‘The long-term requirements of the occupants, such as mutual support, accessibility, comfort, energy use and adaptability’, were crucial in the design solution, explains the architect. The project was built according to Passivhaus principles. A specialist timber frame manufacturer was involved, while an air-source heat pump and MVHR (mechanical ventilation with heat recovery) provide heating and ventilation respectively. The aim was for the house to have a very low energy usage.
Elephant World by Bangkok Project Studio
Elephant World’s architecture nods to both human and elephant needs, showcasing a strong sense of social sustainability but a respect to the environment too. The Wallpaper* Design Awards 2021 Best Sanctuary winner is a design by Thai architect Boonserm Premthada and his practice, Bangkok Project Studio. Premthada worked with local labour and materials to create a complex dedicated to the wellbeing of humans and animals, including an observation tower, a museum and a multifunctional event space. The design blends with the landscape and uses natural materials. For example, the bricks used for the museum were created on site by local workers using loam found in the area.
Powerhouse Telemark by Snøhetta
This ultra-sustainable workspace is a building that actually creates more energy than it will consume over its entire lifespan. Architecture studio Snøhetta, together with collaborators R8 Property, Skanska and Asplan Viak, has recently completed the project, Powerhouse Telemark, the fourth energy-positive building in its Powerhouse portfolio. Located in the city of Porsgrunn, the project creates much needed office space. It features solar panels on its roof; natural shading is promoted, while plentiful insulation ensures heat is retained where possible; and heat is stored in the building elements, to be released slowly, while a geothermal well supports heating and cooling. As a result, Powerhouse Telemark was awarded a BREEAM Excellent certification.
Anandaloy by Studio Anna Heringer
German architect Anna Heringer’s Anandaloy project in rural Bangladesh is a successful example of sustainable architecture, both in terms of social and environmental responsibility. The community centre and textile workshop in rural Bangladesh contains a therapy hub for people with disabilities on the ground floor and a fair-trade textile manufacturing workshop for local women on the first floor. Made out of rammed earth and bamboo, the structure explores age-old local building techniques and materials in soft curves and textures that connect with its place and the region’s vernacular. The building recently scooped the prestigious Obel Award for 2020.
Treehouse by Olson Kundig
US architect Tom Kundig, of Seattle practice Olson Kundig, is behind this sustainable teak holiday house in Costa Rica. Called the Treehouse, the private home is built predominantly out of locally harvested teak, and is open to the elements. This makes sense for Kundig’s clients for two reasons: as avid surfers, it gives them a chic version of a basic surfer’s hut; and as environmentalists, their new home ticks a number of sustainability boxes. Spanning three floors, the building is designed to operate passively, and slatted panels keep it open to the outdoors. ‘Our aim was to create a home that is very leaky to the view and light and air,’ says architect Tom Kundig. The structure also has its own rainwater collection system.
Bahareya Village by ECOnsult
Egyptian architect Sarah El Battouty, head of local studio ECOnsult, led the sustainable design of Bahareya Village, an eco-friendly compound for farm workers in the country’s Western Desert. Created to be home to the farming community engaged by organic tea producer Royal Herbs, the complex uses gravel manufactured from recycled construction waste for the base of its minimalist concrete structures. Cacti scattered throughout the campus offer splashes of greenery without compromising on a commitment to water efficiency. And a technique El Battouty borrowed from desert communities – raising the foundations of the buildings to create distance between the floor and therefore the rising heat from the land – reduces indoor temperatures by eight to ten degrees.
Cold Spring Residence by Alloy
This minimalist and highly eco-friendly house overlooking the Hudson River Valley is the country home of New York-based Alloy’s principal, architect and developer Jared Della Valle. Named Cold Spring Residence, the house sits on the land as lightly as possible. Della Valle worked with passive house sustainability standards to create his retreat, including solar panels for year-round energy, a well-insulated building envelope and careful management of the site’s water resources. The building is also partly sunken and cannot be seen from the street, aligning with its creator’s desire for a ‘a degree of modesty’, so that the architecture doesn’t compete with the striking surrounding natural landscape.
Copper Hill by BIG
The Amager Resource Center in Copenhagen, also known as Copenhill, is one of the city’s latest initiatives that put climate action to the forefront. Designed by the Bjarke Ingels Group (BIG), the building is essentially a rubbish burner; yet it’s also so much more than that. The structure houses an artificial ski slope, recreational hiking area and climbing wall on top of the waste-to-energy plant. Built using aluminium blocks, this piece of infrastructure aims to treat 400,000 tonnes of waste annually. The result is supplying 150,000 Danish households with district heating and 70,000 with electricity from non-recyclable waste.
Flying House by Martand Khosla
Created by architect Martand Khosla for a Delhi-based family of four, this weekend retreat in India’s Dharamshala is rooted in traditional materials and techniques. Set between farmland and a lush forest on the Dhauladhar mountain ranges of the Himalayas, Flying House has been built using local resources – stone, stabilised mud brick, slate and pine. A lot of the earth and stone dug out from the site during the foundation excavation went back into the construction. Building site wastage was minimised and a lot was recycled, making this house quite literally of its place. The construction uses stabilised mud brick, a method local workers were taught, using equipment from Development Alternatives (a social enterprise for sustainable solutions in India). This way, not only would the local stonemasons be able to build this particular house, but they would be able to master the craft and continue using it in the future.
