The RIBA House of the Year 2021 has been announced – Alison Brooks Architects’ House on the Hill has scooped the coveted accolade, which crowns it the best house in the UK in the past year. The winner, revealed this evening (8 December 2021), beat off stiff competition from six striking homes – from urban abodes to countryside retreats and inventive industrial redesigns. The jury, comprising architect and jury chair Amin Taha; architect Cany Ash, of Ash Sakula Architects; and architect Kieran McGonigle, co-founder of McGonigle McGrath and RIBA House of the Year 2019 winner, praised the scheme for its well researched, thoughtful and proportionate design. 

‘Some decades in the making, the replacement of a very large 1970s shed housing a pool and ancillary spaces with Alison Brooks Architects’ lower scaled and fragmented form impressed the jury, in a highly competitive year with contenders excelling in sustainability, craftsmanship, reuse, economy of means and thought-provoking sensitivity. House on the Hill balanced these where others may have, for instance, reused but at disproportionate cost, or crafted but to no innovative end, says Taha. ‘The jury felt Alison Brooks Architects had applied its long-researched process of subtly breaking down the rigid and spatially predictable grid with gentle inflection. Adding depth of scale and richness of experience to the existing house, and through the new extension, transitioning with ease into the beautifully landscaped gardens. It is a model of architectural approach applicable to all scales, resulting from the architects’ long practised ideas and the clients’ successful collaboration.’

House on the Hill is the redesign and extension of a historical Georgian farmhouse in Gloucestershire. Alison Brooks Architects took inspiration from the nearby Forest of Dean for the new volume’s dark tones and cladding pattern. The project overlooks the Wye Valley in an Area of Outstanding Natural Beauty, so taking the surroundings into account was crucial for the design; even though the addition is now larger than the original 18th-century stone farmhouse, it feels at home in its rural setting. At the same time, sustainable strategies incorporated in the new build mean the structure remains respectful to its green environment. Examples include a ground and air source heat pumps, solar panels and a green roof.

‘It’s a real honour to win RIBA House of the Year amongst an accomplished shortlist of beautiful projects,’ says Alison Brooks. ‘I see private house commissions as a rare opportunity to test new ideas in a concentrated form – they are the built equivalent of writing an essay. So, this accolade is a testament to my client’s belief in the value of architecture and their willingness to embrace the new. I’m grateful for their trust in me and my team of talented architects, in Akera Engineers and the brilliant team of builders and gardeners whose skilful contributions produced this remarkable house and gardens, that together reveal a new way of living in the landscape.’

This urban home in London is a new end-of-terrace house that completes the row in its residential street. Picking up on the Victorian language of the neighbouring structures, the new design offers a contemporary twist to the well- known typology through abstracted forms and finely tuned details.

A family cottage in a suburban setting has been beautifully remodelled for Theo and Oskar, who suffer from Duchenne muscular dystrophy. The redesign and extension takes this into account, achieving a space fit for their daily needs and reducing mobility.

This remote countryside abode is at one with its craggy environment, clad in timber and keeping a low profile to allow the surroundings and views to take centre stage. At just 100 sq m, it is also very sustainably composed.

This barn conversion takes advantage of the existing, historical structure’s masonry, scale and proportion to transform it into a generous home that feels entirely in sync with its surroundings. The Outfarm is an exemplar of how to make a 21st home out of a neglected and seemingly outdated farmhouse building.

Converting a disused historic Water Tower into a modern home is not your usual residential commission; but then again, Tonkin Liu are not your usual architects either. Working with the existing industrial structure and its rawness, the team offered a new use and design fit for the 21st century, and full of surprises.
