Eco-practice Tate Harmer has completed this £180,000 timber extension to a family house in Shepherds Bush, west London
The East London-based practice, who have prevously completed passivhaus projects, has used exposed timber throughout the 140m² residential project. The extension has a geometric, semi-arched shape that leads onto a cantilevered covered patio space.
The 45° pitch of the scheme’s roof was driven by a local planning bylaw. Structural wooden ribs extend into design features such as bookcases, with rooflights between the beams.
The floor is made from engineered hardwood, with under floor heating, whilst the beams are glue laminated timber (glulam). Used as a
steel alternative in 70s and 80s industrial building, it rarely features in domestic buildings.
Jerry Tate founding partner at Tate Harmer said: ‘We often use timber frame in our residential projects, there are great benefits in terms of the speed of construction and the amount of insulation you can include. But also, really importantly, a natural material like timber can create a beautiful warm feel to a space and on this scheme the daylight filtering through the exposed timber beams gives a lovely quality of light.’
