The Sturgis's walls, floor and ceiling are all cross-laminated timber panels—3.25-inch thick sheets of douglas fir, manufactured in Montana and assembled at the Cubist Engineering shop. The box's air-tight construction and passive solar gain through the large windows means most climates need no additional insulation. Photo 5 of 7 in The Sturgis by Cubist Engineering
