Backyard cottage in Seattle. The existing conditions of the site left us with a tiny corner of the property in which to build. Furthermore, the zoning restrictions in Seattle only allowed us to build 800 sq ft. The result was an L-shaped building created from two interlocking gable end blocks — one was 13'-2" x 23-0" and the other was 13"-2" x 24'-0". On the main floor is a garage/workshop. On the second floor is a studio apartment with a vaulted ceiling over the living space.
