His 1000 sq.ft. circular house could be put together by a couple of people in less than 2 days, weighed under 3 tons (lots of aluminum), self-cooling. It was supported by a single mast, and portable. 80 years ago, the ‘kit’ cost $6500, delivered.
You can see the only still-existing house at the Henry Ford Museum site. https://www.thehenryford.org/visit/henry-ford-museum/exhibits/dymaxion-house/
That’s about 120k in today’s money.
Yep. OTOH, I recently saw a regular old, nothing-fancy home built at about that same time sell for $450k.
