Constructed of laminated glass beams and roof panels, with glass doors, this entry space is conceptualized as an exterior circulation connection between the private and public wings of the house. The exterior walls are constructed of 12” thick insulated cast-in-place self consolidating concrete, and a metal roof helps to provide maximum fire resistance in this secluded canyon. Interior floors are lightweight concrete. The exposed concrete is warmed with doors and windows of natural mahogany and interior millwork and ceilings of natural eucalyptus. The main floor of 4,700 square feet includes a studio, family room, kitchen, dining room, living room, office and master suite. A lower floor of 2800 square feet includes guest rooms and an exercise space and mechanical space.
