The client had a simple request: to open the back of the house to the yard. The operable glass wall on the first floor allows the project to act both as a room within the house and a sheltered extension of the yard, which is used primarily as a plot for growing vegetables and grapes. The new interior spaces defined within and adjacent to the house are surrounded by thickened walls which house storage, appliances, insulation, wiring, plumbing, and lighting – all the trappings of domestic life - and also interlock with the larger enclosure of the yard. The surfaces of the project exposed to rain are clad in recycled, reflective, fluted aluminum shingles, while the surfaces protected from moisture are clad in white-washed plywood. In contrast to these monolithic surface treatments, the floor surfaces and depth of the wall are treated with a collection of textures ranging from black concrete to grass, organized to create subtle spatial differentiations within the larger spaces of the project.
