it’s the Frank Lloyd Wright curse: his houses are beautiful but maintenance nightmares - the first time you build a new design, it’s going to leak. as soon as you get creative, you’ll get seams that settle and crack in unpredictable ways.

cubes are not the strongest form (rhombic dodecahedrons are better) but it’s not the weakest form either, you start playing with acute and obtuse angles you might come up with something fragile. best to stick with right angles.

I turn my nose up at rectangular buildings as much as the next guy (my house, at least, is an octagon) but we’ve become very skilled at building rectangles that don’t leak / collapse.
