IMO, dome shaped houses are a disaster.
Unattractive and not as resistant to adverse weather as they claim. The winds can still lift the roofing shingles off the roof from the direction the winds are coming from.
And they don’t look very space efficient. Closets in shapes of wedges with curved walls? Bedrooms with curved walls? How to beds and dressers fit in there without wasting space?
What about kitchen cupboards and countertops?
Shingles won’t lay very flat on the surface of a dome like the one pictured. The “roof” pitch is not the same on all parts either, so you’d need to be careful with the nailing too. The windows and doors will be more likely to leak as well.
