Just completed Backyard Cottage / DADU in North Seattle. This was designed as a separate residence for an Au Pair, to take care of the owners’ children. It’s a very efficient one-bedroom unit, with a light-filled main room, galley kitchen, and a surprisingly gracious bathroom. Its shed roof slopes up to the south, to draw more natural light into the spaces, and has an upturned butterfly roof over the living room, with a deeper overhang there to allow use of the patio on drizzly days.
