About this home

One-of-a-kind California ranch-style property on 20+/- acres in the rolling western hills of Calistoga. Published in House Beautiful and characterized by natural, rugged, durable building materials of earthy tones, this property exudes a sense of calm, relaxation, and peace of mind. The property was designed with expansion in mind. The size and location of the current structures allow for the addition of a main residence. The property currently includes a Robert Gregory Architects custom designed native stone and cedar plank guest residence with two private suites carefully positioned among glorious Heritage oaks. The suites are connected by an airy breezeway that functions as an open-air dining room with stone-wrapped BBQ area and adjacent to a calming fountain wall. Lower on the property sits a truly modern Rela Gleason designed black metal designer barn also with two guest suites and garage space for 2+ vehicles and/or maintenance equipment. This dispersed property is a perfect retreat for two, a family compound, or a camp for entertaining overnight/weekend guests. Minutes to Calistoga and slightly over an hour to the Golden Gate Bridge.
