Since founding Faulkner Architects in 1998, in Truckee, California (near Lake Tahoe), and later establishing an office in Berkeley, Gregory Faulkner has designed 20 ski retreats. The CAMPout house, some 6,800 feet above Lake Tahoe, demonstrates his sleekly natural approach. The client, Rowan Trollope, the CEO of Five9, a publicly traded cloud-software company in San Francisco, likes extreme ice climbing, cross-country skiing uphill (with no-wax skins), and camping in the dead of winter with his two youngest children.
