On all levels, the geometry of the exterior walls intersecting the strictly orthogonal inner geometry creates a series of unusual spaces. In contrast to the rough, poured-in-place concrete walls are the interior walls, constructed and partially sheathed in wood. Large openings in the concrete wall provide vehicular and pedestrian entries on the lower levels, and give access to outward views on the middle (bedroom) level. The carefully choreographed movement through the house, leading from dark to light, begins at the entry space on the mezzanine level, leads up to the bedroom level and then to the upper-most level. Open to the outside, the living and dining space, a small study and the open kitchen are organized around a central, sculpted wood-clad core. The roof rests on five steel columns and the entirely glazed perimeter affords spectacular 360-degree views of the bluff to the north and city/ocean views to the south.
