Hupomone Ranch is an original homestead located in the Chileno Valley, just three miles west of downtown Petaluma in California, USA. The ranch had been empty for over 30 years and the owners, a young family with three children, wanted to build a barn house that would reflect their commitment to sustainable farming. According to the architects at Turnbull Griffin Haesloop, the simple grounded form of the barn was built to complement the surrounding landscape and capture the long views of the coastal range beyond.

Set into the more opaque north side, the entry provides shelter tucked under the loft above and frames a view through the house to the meadow beyond. The light-filled living area opens up to the long southern view, with the bedroom and kitchen flanking either side. The kitchen’s slide-away windows open directly to the garden.

The landscaping by Lutsko Associates was an integral part of the design and includes several outdoor living areas, organized along a riparian restoration and native plantings, while Erin Martin’s interiors complement the flow of indoor/outdoor living.

Passive heating and cooling with thermal mass and insulation, geothermal, radiant cooling and heating along with solar and photovoltaic panels contribute to the house’s energy efficiency. [Photography courtesy of Turnbull Griffin Haesloop]
