While many extensions to the typical ‘two up two down’ house create an aesthetic division between old and new, we wanted to blur the lines between these conditions. Our approach was surgical. Through a series of cuts and openings in the existing, visual connections are created from the street to the new extension to the garden beyond. The existing rear room was stripped of its plaster to expose its brick construction, relating it to the new brick extension. The shared structuring material of concrete links old and new together spatially and materially. The result of these blending interventions is a series of characterful and livable rooms that are distinct but cleverly interlinked.
