Designed by Olson Kundig, this concrete, glass, and steel building encourages natural ventilation and passive solar shading. The roof collects rainwater stored in a cistern for non-potable uses within the house and garden.

The main floor is an open living, dining, and kitchen area, and a steel-clad box near the entry houses a powder room and pantry. Floor-to-ceiling window walls and sliding glass doors make the home's smaller footprint feel larger and more integrated with the outdoors. The house’s openness and sense of transparency are sustained by steel stairs that are suspended (without risers) between the north wall and a thin steel plate.

Private areas are located at the top of the house. A study overlooks the front terrace and street, while the master bedroom and attached deck look west toward an arboretum and downtown Seattle. The master bathroom is fitted with an unenclosed shower and freestanding refinished claw-footed tub, which empty into a trough drain.

The lower level of the house holds a mudroom, guest suite, laundry, and storage areas and opens up to a carport, garden, and small apiary. The carport roof functions as the deck surface on the main level.
