This 1750-square-foot, off-the-grid residence in the California Gold Country, outside the town of Murphys, was designed as a summer and winter vacation house for a San Francisco couple with two young children. The home is divided into “live” and “sleep” buildings, each about 875 square feet, which are sited to capture views. The gap between the buildings funnels breezes from the valley below. The courtyard is a calm, encompassing space for relaxation and play.
