This self-build project fitted in around the architects’ home lives. On a 2.8m wide plot behind the architects’ property, a two-storey, one-bed scheme was constructed using a lightweight steel frame on a piled slab. The steel was prefabricated as portal frames site-welded together. A palette of spruce plywood, Douglas fir joists, terrazzo and cork flooring characterises the interior. Timber framed walls are externally clad in handmade pewter glazed brick slips with a patina that reflects the changing light. A simply landscaped rear courtyard and front garden enhance the feeling of space in a small infill dwelling.
