They could really build geodesic domes in those days. Most of the abandoned domes are intact, after half a century, unmaintained, in an Arctic climate. They're aluminum frames with Fiberglas panels.

Geodesic domes were taken over by the "natural materials" people in the 1960s and 1970s. This doesn't work. Geodesic domes need standard manufactured components built to tight tolerances. Then they just bolt together. Domes built with wood and shingles do not work very well.[1]

Google proposed to build a big geodesic dome for their HQ in Mountain View. It probably would have been better than what they did build, which looks like some kind of sports arena.

Bolting together at a variety of odd angles is a terrible thing to waterproof, and most domes do have water infiltration problems. You can just spray foam the whole thing, building a dome of polyurethane, but if you're going to do that you're getting very far from the ideals of that movement. Wood and shingles are also not isotropic materials structurally or in terms of how they deal with moisture.
