The house was conceptualized as three separate elements comprised of two living units and an interstitial space tying them together. A clear division exists in plan, elevation, and section separating the active portions of the house from the inactive. The clients have two grown children who will not live in the house, but need their own rooms. Those rooms are separated from the master bedroom by a bridge on the second floor. This portion of the house becomes active only when the children or guests are in the house. Thus, the basic living pattern of the family becomes manifest in the form of the house.
