The circulation of the house weaves through a modulation of intimate and expansive spaces and courtyards that lead to a glass-enclosed single-story space at the rear of the property. This is the kitchen and family room, the heart of the house. It also defines the south edge of the courtyard. This volume has been pushed down to one story in order to permit light to the interior and views out to the ravine. Large expanses of glass dematerialize the monolithic stone building and dissolve boundaries between the interior and exterior.
