This small semi-detached single-level house in Edinburgh, Scotland was recently renovated by David Blaikie Architects. The 731-square-foot home did not provide enough space, so the focus of the expansion was to increase the size of the living room and a build an additional small bedroom upstairs.

Thermally modified timber cladding for the roof and siding, steal frames and glass define the exterior of this family home. “The tall frameless glazed corner cantilevers out over the garden giving a lightness to the massing,” explained the architects at David Blaikie. “The extension is invisible from the street side of this semi-detached house, but explodes out of the rear elevation in a wholly unexpected way.”

Function was the main consideration when planning the shape of this addition. “The extension and development of the attic space more than doubles the floor area of the house – all on a very tight budget,” the architects added. Living areas are illuminated from dusk till dawn, thanks to expansive windows ensuring a good flow of natural light.
