A rigid shell or framework (10) for a building structure, comprising a first pair of spaced supporting frames (11, 12) defining the end walls of the shell, a second pair of spaced supporting frames (13, 14) disposed at right angles to the first pair of frames and defining the side walls of the shell, and a plurality of further supporting frames (15) disposed intermediate the first pair of supporting frames, being supported by the second pair of frames, and in turn providing the structural support for the side walls, roof and floor defined by the rigid shell. The first pair of supporting frames comprises a pair of vertical load-bearing members (18, 19) integral with and secured to a pair of horizontal load-bearing elements (16, 17) at points spaced from the ends of such elements by from 1/8th to 1/4th their respective lengths. Vertical load-bearing members (22, 23) of the second pair of supporting frames (13, 14) also abut and are secured to the vertical load-bearing members (18, 19) of the first supporting frames (11, 12) along substantially their entire lengths to define four load-bearing columns (24) for the shell. Internal sheathing (37) and an external skin (38) provided on the plurality of further supporting frames (15) of the rigid shell define an annular cavity (43) extending about the periphery of the shell for solar heat collection and air circulation therethrough. The integral shell structure thus inherently defines an air circulation path extending about the side walls (39, 40), roof (41), and base (42) of the structure to facilitate efficient use of the structure for solar energy heat transmission.
