The tower assembly is comprised of vertically stacked tower sections each of which includes a pair of primary frame structures having end posts and interconnected by frame units in a variable spaced parallel relation so that the end posts constitute corner posts for the tower assembly. A pair of secondary frame structures corresponding to the primary frame structures may be connected to the frame units in a parallel relation adjacent a corresponding primary frame structure, or only one of such secondary frame structures can be so assembled relative to its corresponding primary frame structure. Additionally, the primary and secondary frame structures can be relatively extended upwardly of the tower assembly to support separate loads at varying levels.
