Structure forms a central focus of architectural expression in this 5,000 square foot residence. Numerous integrated design features speak to the collaboration between Anne Fougeron Architecture and what was then EndresWare, now Endrestudio. For example, the need for a 12" deep moment frame was eliminated by using steel in the stair to create a braced frame, reducing the member sizing to 5". The slender and elegant braced frames showcase the integration of structure and architecture as they follow the line of the stairway. A two-inch torsion tube provides support for the stairs and allows the marble treads to float within a luminous glass stairwell. Custom tapered fin columns (exposed in the living room) ground the space while providing a visual explanation of how the building works. Delicate microcolumns support the roof at continuous clerestory windows, which allow light to filter down through the spaces below. The 440 Residence was the winner of the 2000 AIA Best of the Bay Architecture Award for a single family residence and the 2000 Dupont Benedictus International Glass Award.
