The net-zero ranch comprises a cluster of buildings that frame and protect a sunny central courtyard from strong winds. The courtyard’s plunge pool and hot tub were strategically placed to overlook views of Mount Tamalpais. The spacious interior features large communal areas as well as numerous bedrooms and bunkrooms to accommodate an extended family of sixteen. Reclaimed wood floors line the open-plan dining and living spaces.

Clad in handsome Western red cedar and topped with a corrugated zinc roof, the solar-powered house includes zoned radiant heat and high R-value insulation that keeps the heat from escaping outdoors. A rainwater capture system collects and reuses runoff for toilet flushing. The architects also incorporated passive cooling techniques and installed stainless steel sunshades to shield the interior from solar heat gain.
