I think it has to do with prices and available know-how. You can build a typical US home for 1/2 or less than a Central European home. Right now, if I were to build a 150m2 (1600sqft) home, that would cost me at least €250k. More likely 300. Zoning often requires houses to be of a certain build and look, so building cheaper than that is often not even an option. As far as I know, a US home of that size usually costs $100k? Please someone correct me if I‘m wrong.
