This new three-story modern home is organized around a circulation/service area spine that maximizes the width of the entertainment rooms and gives a rational framework to the house. The formal living room is separated from the kitchen/family room by a dramatic Tansu-inspired staircase, which leads to the bedroom level, capped with a skylight, flooding the center of the house with natural light. The classic simplicity of the exterior enhances the restraint of the elegant interior. Finishes are mostly natural with cherry cabinets and steel trowelled stucco. A roof top terrace provides sweeping views of the Golden Gate Bridge and Marin Headlands.
