Exterior, Metal Siding Material, Cabin Building Type, Glass Siding Material, House Building Type, and Gable RoofLine Built by a crew of three, the home makes a virtue out of being unfussy and straightforward. The north-facing glass wall under the gable, with a triple-glazed facade, doesn't require shading or insulation.
