The late architect Robert Overstreet spent roughly a decade perfecting his dream home, a sculptural geometric retreat nestled among the ancient redwoods of Marin County.

A bespoke Italian kitchen anchors the main living spaces with frameless cabinetry, Calacatta marble, and a quartz waterfall island, while a walk-in pantry is cleverly concealed behind pivoting doors.
