Inside, Deeds created a wall-to-wall sofa (supported by a square steel tube) with storage drawers underneath. A single shelf provides more storage. “The thick insulation and the passive solar features perform wonderfully,” says Deeds. “The building is very comfortable without supplemental heat. When it is too cold I warm up the room by turning on a few lights and my computer, and sometimes I bring a large dog inside or do ten jumping jacks to generate some heat. Because of the insulation, the heat sticks around.” Photo by Lenny Gonzalez Courtesy of © Lenny Gonzalez 2010.
