The stackable building structure frame can be secured in a collapsed condition whereby to facilitate transport, storage and the erection of such building structures. The frame is comprised of reinforced connecting plates secured to opposed corners of a roof frame and to a vertical support post secured thereto. The connecting plates permit the vertical posts, which constitute the side walls of the structures, to be folded under the roof assembly. The vertical posts are secured to the connecting plates by a pair of connections one of which is a hinge connection. These vertical posts are interconnected in a folded condition by connecting vertical leg braces which are also the adjustable legs for the vertical posts. Stacking corner support legs are detachably secured to opposed corners of the collapsed building structure frame to permit stacking of these collapsed frames one on top of each other.
