Maple Leaf Family DADU

On our most recent project, we took advantage of a large lot and Seattle's new ADU rules to design a 1000 sf, 3 br / 2 ba,  DADU with an attached garage.   The project also included a full basement for additional storage, an office and a rec room.  Exterior foam insulation, exceptional air tightness, a mini-split heat pump, and a heat recovery ventilation system resulted in an extremely energy efficient DADU.
