In Seattle’s Mt Baker neighbourhood, Lil Shingle by Best Practice Architecture revives a 1950s home into a multigenerational base. Once nicknamed the Slanty Shanty for its failing structure, the two-storey dwelling was rebuilt almost entirely, keeping only the concrete foundation. New cedar shingles and baby blue doors refresh the exterior, while vaulted ceilings, skylights, and sliding glass doors bring light and openness inside. A small mudroom extension provides functional entry space, and a new deck frames views of Lake Washington and the Cascade Mountains.
The project was a family collaboration led by a daughter who is a principal at the studio, with her sisters contributing stained-glass windows and interior curation. Relocating the staircase freed circulation and expanded shared living zones. The basement now functions as an accessory dwelling unit with bedrooms, kitchenette, and gym. Lil Shingle shows how preservation and reinvention can meet in a home designed for family life.
