Abstract: A building assembly includes a floor frame, a roof, and walls extending between the floor frame and the roof and interconnected to define an interior and exterior of the building assembly. Each wall includes panels each defining an axis and having first and second ends, inner and outer sides, top and bottom surfaces, an upper notch formed through the top surface, and a lower notch formed through the bottom surface. Each notch is spaced inwardly along the axis from at least one end. The panels include first and second panels. The lower notch of the first panel mates with the upper notch of the second panel to form an interlocking joint to interconnect the first and second panels and form adjacent interconnected walls of the building assembly.
