I've been contemplating building a large-ish shed but I'm stuck on the foundation. It's New England so inevitably the structure will sink into the ground without a foundation, but I don't want a permanent foundation. Clearly it would be ideal to have a grid of supports underneath the shed with adjustable height (maybe using some sort of threaded mechanism), and make it possible to adjust those risers automatically through some sort of self-leveling like what a 3D printer does. But of course now I will never actually build this :-)
