Project Description

Hupomone ranch is an original 160 acre homestead located in the Chileno Valley, just three miles west of downtown Petaluma, California. The ranch had been fallow for over 30 years and the owners wanted to build a family house that would reflect their commitment to sustainable farming, draw on the natural serenity of the site, and build on the sense of place in western Petaluma where farming and ranching are still a part of people’s daily lives. The site has a wonderful balanced quality to it, and the simple grounded form of the barn shape is sited to compliment this setting and capture the long views to the coastal range beyond. Entering a low porch on the more opaque north side under the loft above, the light-filled house opens up to the long view south and gathers the bedrooms and kitchen to either side. The house is certified LEED Platinum and has a number of energy saving features, exceeding California's Title 24 by over 50 percent. The house's energy efficiency is achieved in part through passive heating and cooling with thermal mass and insulation; geothermal radiant heating and cooling; and solar and photovoltaic panels. An integral part of the design, the landscaping by Lutsko Associates includes several outdoor living areas, organized along a riparian restoration and native plantings.
