Hupomone Ranch is a minimalist house located in Petaluma, California, designed by Turnbull Griffin Haesloop Architects. Hupomone Ranch is an original 160-acre homestead located in the Chileno Valley, just three miles west of downtown Petaluma. The ranch had been fallow 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, 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.
