An eco-conscious reconfiguration of space revives a London home
An eco-conscious reimagining of a Victorian terraced home for a growing London family, THISS Studio’s Hartley House offers sustainable, spacious living

When the clients of this eco-conscious project first approached THISS Studio intending to expand their Victorian terraced home in Waltham Forest, to accommodate a growing family, they didn’t realise they already had all the space they needed.
Rather than pursuing a costly, carbon-intensive extension project, the London-based architects reimagined the brief and proposed a thoughtful plan to reconfigure the existing space. The result is Hartley House, which stands as an exemplary case of sustainable architecture and creativity at a time when the consequences of carbon-intensive building practices are widely understood.

As Sash Scott, founder of THISS Studio, explains: ‘By rethinking the home as a team, we have saved a significant amount of carbon and enabled our clients to redirect their budget into higher-quality, more sustainable materials and fittings. This ensures their home not only possesses a renewed sense of beauty, but also that they will love living in it for many years to come.'
While the Victorian architectural elegance remains, the studio’s work introduces a contemporary sense of spaciousness, playfulness, and sophistication. The redesigned kitchen – bright, tall, and airy – now serves as the centrepiece of the home. By subtly borrowing space from the outside, the architects integrated a cantilevered dining bench framed by three oversized sash windows. Upon discovering additional room beneath the original kitchen flooring, THISS Studio gained an extra meter of ceiling height.
The kitchen
A locally handmade, custom-designed kitchen crafted from FSC-certified pine timber evokes a sense of timelessness. Mint green floor-to-ceiling bespoke shelving, terracotta tiled flooring, and pale cream acoustic wall panels made from recycled paper-waste create a harmonious balance of colours and volumes.
The studio
Access to the garden is carefully curated, with the kitchen’s terracotta flooring tiles flowing seamlessly outdoors to form a circular patio. A curved canopy of laser-cut recycled aluminium protrudes from the corner of the house, providing shade and weather protection for the Douglas fir windows. This playfully organic shape is mirrored by a smaller aluminium ledge that can serve as a seat or table.
THISS Studio also redesigned the living room and studio, which had previously served as the kitchen. Bright butter-yellow interiors infuse the space with warmth and brightness, accommodating family leisure activities while also providing a peaceful workspace.
