Abstract
Abstract A model house that can be erected from a combination of parts without tools or fasteners and then easily knocked down for shipment or storage. A base member has a main cutout to receive a central vertical partition and peripheral openings to receive vertical side members that support a second floor and a folding roof. All parts are rigid members that interlock so that they cooperate together to maintain the structural arrangement of the house.
