Thick wooden ribs frame this extension to a family house in West London by architecture studio Tate Harmer.

The Dalston-based architects were first tasked with overhauling the interior of the Edwardian-style house, which is located within a conservation area in Shepherds Bush. But they were also asked to extend a small kitchen at the rear of the property to create a more generous dining area.

Rather than continuing the brickwork of the original house – like recent London extensions by Fraher Architects and Cousins and Cousins – timber was selected as the main building material for the extension. It provides the framework for the walls and roof, and surrounds windows, doors and skylights.
