Would you want buy one?

Yes. I know someone with a concrete house, and they won’t shut up about how awesome it is. Kind of like Tesla drivers. And they retain heat and cool air.

It is an upside down pool.

I am absolutely certain that this house costs a quarter of what it does to build a traditional house of the same size but they will charge five times as much instead. So no...I would not buy this.

Nope it will crack leak and leak.

I would. You can easily design your own house. Concrete doesn't burn either.

Very little information on their website. Nothing about insulation (concrete is basically rock) or wiring or plumbing or HVAC. Guess they want you to contact them.

This is actually relatively old technology. Here is the original version with a much more informative website.
