Faulkner Architects perches Big Barn house on Sonoma Valley hillside

American studio Faulkner Architects has completed a holiday home in California’s wine country with an asymmetrical roof and facades wrapped in weathering steel and salvaged wood.

Called the Big Barn house, the project is located in Glen Ellen, a town in Sonoma Valley that is named after a winery established there in the 1860s. Located about an hour’s drive from San Francisco, the area has rolling hills dotted with oak trees and agricultural buildings.
