Here are progress photos of a new DADU (Detached Accessory Dwelling Unit) under construction in North Seattle. This is a 499 s.f. cottage, intended for a live-in Au Pair in the short term, and possibly for in-laws in the future. It’s a very efficient one-bedroom unit, with a light-filled main room, galley kitchen, and a surprisingly gracious bathroom. It has a shed roof sloping up to the south, to capture some extra sunlight through transom windows on that side, and a butterfly roof over the living room. The DADU replaces a run-down garage / shed structure that sat in roughly the same location, so the new cottage fits very comfortably into the backyard
