Designed by Lawrence Architecture, this West Seattle district residence is primarily comprised of three building materials – concrete, steel, and glass. The end result is a 3,800 square foot home that is very modern. A large concrete wall essentially separates the home into two main sections, where a garage, entry and service spaces are on the side that faces the street, while the main living space is on the other side. This setup was chosen to maximize privacy. The wall itself houses stairs with cantilevered steel treads. Above, a sweeping, arching roof sites atop the wall and is supported by steel frames and triangular steel trusses. As for the main living spaces, the master bedroom is a loft above the kitchen, while other rooms are at basement level to maximize daylight.
