“Designed by Mork-Ulnes Architects, the Triple Barn House is a rustic retreat made of glass, concrete, and steel.
Perched on a six-acre parcel just minutes from downtown Sonoma, California, is a steel-clad dwelling known as the Triple Barn House. The two-level home was built in 2016 by San Francisco–based Mork-Ulnes Architects for a couple seeking to reconnect with nature.
Inspired by the area’s rural building typologies, the firm wrapped the home in metal cladding reminiscent of the iron-red soil found at the hillside site. “We chose Cor-Ten steel as the cladding material for its natural resistance to fire, as well as its resonance to agricultural buildings of the Sonoma Valley,” says Casper Mork-Ulnes, the firm’s founder. “The natural soil of the Sonoma hillside is very iron rich, which gives it a rusted color, making the house tie back to earth.”
