Tower, Sarasota, FL, 1954 Project Not Built
"Rudolph’s 1950s idea of a central core with office or residential units hung on all four sides by cables from cantilevered beams or trusses at the top persists in his thinking. He visualized mobile home or truck van units plugged into vertical hollow structural tubes carrying the elevators, stairs, and mechanical services for these living units. Practically, the problem was that its rectilinear geometry limits to six or eight floors the weight of hung units per support grid. A more defined drawing of trailer-like modules appears in his 1954 Sarasota high-rise sketch of this idea with four service towers."
