His design uses two 8′ by 40′ containers placed side-by-side. A small wood-framed entry at the front bumps the floor plan up to 672 ft2 (62.4 m2). A roof supported by glulam beams was built on top to form wide overhangs, a covered entry porch in front and a larger porch or carport to the side. That allowed the metal container ceiling to be left exposed on the inside. The walls, however, were insulated and finished on the interior so the durable container walls could function as the exterior siding.” – Small House Bliss
