we rented a dome mountain cabin last weekend. Built in 1977. The idea was popular around then and a little earlier. Claim was maximum interior volume for minimal heat loss/gain through exterior skin.
Lots of weird wasted corners etc. Half of it had 8' vertical walls then dome on top. The other half had vertical walls to window sill height. Seems like a shop could be built with a big span. I think the introduction of roofing trusses kind of killed the idea. Also the roof/walls are not thick enough for modern insulation levels. Looked like a lot of infill with tricky stud angles for the drywall and plywood exterior skin.
