New York firm Studio Joseph was approached by a husband and wife, both scientists, who wanted to build a compact, off-the-grid home on their 25-acre property in Sonoma that reflected their passions: maintaining their olive orchards, bee-keeping, and other activities that take advantage of California’s climate. “They wanted the dwelling to be one with the landscape,” says architect Wendy Evans Joseph. “Our goal was to make a home that was as much about the indoors as the outdoors.” Working carefully to leave the site’s foliage undisturbed, her team installed new water lines along existing paths. A custom solar array powers the entire property. Anchored by a series of concrete walls that splay into the hillside, the 850-square-foot home is focused on nature. Each of its three levels has an indoor and outdoor function: The entry-level bedroom and bathroom connect to a balcony, a half-level down, the kitchen leads to a deck for alfresco dining, and the living room features a seating alcove that looks out onto the orchard.
