The north and south facades are mostly closed to the adjacent houses. High strip windows facing west provide privacy from the street.
Glazing is concentrated on the east, where an inclined 50' long full-height glass wall defines the living area with a dramatic panorama of Lake Washington. Spatial flow moves upward with a open linear steel staircase bisecting the upper floors. A full-length clerestory above brings natural light to the stair and master suite interior.
Exterior materials are to be maintenance-free and include glazed gray brick (which also covers the fireplace block), concrete, and smooth-finished metal panels in two colors. All structural steel is exposed. Dark gray glass wraps the cantilevered master bedroom.
A green roof (watered by collected stormwater) will give extra thermal insulation to the living area and provide rooftop outdoor living. Sustainable features are designed to enhance the modernist vocabulary.
