A single storey gym and yoga studio for a 1920s’ Arts and Crafts style house. The 68 sq m pitched roof extension is designed to be sympathetic to but distinct from the original house and includes a shower room, storage area, gym and separate studio for yoga and pilates. A rooflight running the length of the ridge reduces the height of the roof and brings daylight into the rooms below. Sliding and folding glass doors in the yoga studio open out onto a sunken, York stone paved patio area and the gardens beyond. The roof, supported by four tapered timber columns at the western end, overhangs the patio.
