Maximising space without extending: THISS Studio renews Victorian terraced home in Waltham Forest

THISS Studio has transformed a Victorian terraced house in Waltham Forest, North East London, reviving the dark and cramped ground floor of the property into an airy and comfortable family space. 

A creative reconfiguration of the existing floor plan has created a much-loved, carefully tailored home without the need for an extension, showing that sometimes unlocking the space already in our homes can be just as valuable as extending, with a fraction of the carbon.

Initially approached by the client to design a side return extension on the property, THISS Studio instead re-imagined the brief, honing in on the client’s essential needs: a large family kitchen, a strong connection to the garden, more space to work when the kids are at school, while creating something with a unique sculptural quality that is one-of-a-kind, playful and fun. 

THISS Studio guided their clients to see the opportunities the existing floor area allowed; in leaning into the existing building to create more usable space, the architects avoided the need for a carbon intensive and costly extension. THISS Studio’s forward thinking approach opened up space in the client’s budget for beautiful and interesting finishes and furnishings that echo the client’s personal style, and importantly, adding significant design value to the project.

THISS Studio’s solution involved opening up the back of the existing house and borrowing space from outside by installing a cantilevered dining bench framed by three oversized sash windows that flood the open plan kitchen with natural light. THISS Studio designed a bespoke kitchen handmade locally using FSC-certified pine timber. 

As the centrepiece of the home, the new kitchen-diner radiates openness and authenticity, enhanced by a generous ceiling height overhead. Early on in the project, THISS Studio discovered a large void under the floor, as advocates for leaning into the building’s existing structure, the practice took advantage of the extra space, creating a level threshold to the garden and a stepped entrance into the kitchen. By removing the floor the architects were able to create an additional metre of ceiling height.

THISS Studio has skilfully layered natural tones of wood, terracotta, and pale cream acoustic wall panels made from recycled paper waste. A bespoke floor-to-ceiling mint green shelving unit accentuates the room’s sense of volume, and floral light fixtures are key moments of playfulness that echo the family’s bright personalities.

Connectivity between the interiors and garden has been kindly curated. The terracotta tiled flooring flows out from the interior, forming the circular garden patio. Inside, a subtle tonal shift in the tiles completes the continuation of this circle, happily dubbed the ‘disco ball patio’.

Meticulously crafted douglas fir timber frame glazing fills the kitchen with natural light and offers direct views out into the garden. Beneath, a sunlit built-in bench seat provides an ideal spot for family and friends to come together, a social focal point in the home. THISS Studio adopted a cost-effective solution to achieving a large area of glazing in the kitchen by using sash windows in timber frames, a more economical way to create large openable areas of glazing.

Outside, a curved aluminium canopy projects outwards from the building’s corner. This bespoke feature was laser cut from 6mm recycled aluminium and fixed above the south facing windows to provide shade and weather protection for the douglas fir windows. Its organic shape adds character and whimsy whilst balancing the vertical appearance of the rear elevation. This sculptural gesture is playfully mirrored below by a smaller aluminium ledge that doubles as a seat or table.

The rest of the ground floor also underwent renovations. The previous kitchen was located at the front of the home in what would have been a sitting room. The room has been restored back to its original condition, becoming a restful living/study space painted in butter yellow. A small WC and utility room was installed in the centre of the ground floor plan off the hallway. The interiors are bright, colourful and natural, and imbue a warm sense of character.

The project is a masterclass in how sustainability can be achieved on a budget when approached thoughtfully. No concrete was used in the final design as all works were completed on the existing foundations of the property, resulting in a retrofit with an impressively small carbon footprint. THISS Studio has prioritised the specification of natural, renewable and recyclable materials throughout the design. FSC-certified pine and douglas fir wood were selected for their durability and sourced from Europe, cutting out long journeys in the material supply chain. Additionally, the choice of aluminium for the curved canopy is informed by the material’s infinite recyclability. 

By making the property work harder for the client’s needs instead of wasting budget and carbon to create more space via a costly extension, THISS Studio has created a spacious, sophisticated and bright family home that is punctuated with personality and charm. An exercise in unconventional composition and craftsmanship, the practice’s thoughtful use of space ensures that playfulness finds its place amongst inherent functionality.
