Being that I have become somewhat of a remodeling/retrofitting architect for housing, I can appreciate something like Berstein Architecture's Floating Beds. The framing system of cables with end-bolting presents an idea taken from modern industrial design. Calculating loads maybe the only drawback, as every owner/tenant bring their unique weight. If it was up to me, I would remove the ground cables and let the bed swing away.
