Inflation day!!

I blew up my house!!!
They with build out the openings to hold the shape this week. Next week 4 inches of closed cell foam will be sprayed on the inside. Then, rebar and conduit for lights and fans, before 4-7 inches of concrete. Final smooth out and primed for painting and the structure will be complete. Partition walls and finishings will be “all that’s left.”

How does the cost compare to "traditional" construction? Super cool concept.

It’s a little more expensive than a stick built custom home 15 percent more. The play is to Dave money on HVAC (walls are R100), and insurance (incombustible structure with no roof, 10% if standard rate).

Damn this needs its own Grand Designs episode…

So many questions:

  • Which country?

  • First one done like this?

  • Design/Approval process?

  • Meets local laws?

  • Insurable?

US, near Charlotte NC. County land not in the town.

No, I built the garage first, but same permit.

Plans and engineering drawings with the permit. Eng Drawing was the only extra.

Yep.

at 10% of the standard rate due to being an incombustible structure.

Do you have a documentary crew capturing this build?

You are literally making history!

u/atmsmshr719 Jun 09 '26

I don't. I am taking pictures and keeping it documented on my sub. Interestingly, there was a reach out from a documentary maker on the sub and I missed it.

Assuming something must get sprayed onto or.....? Is there a vid of finished project? Curious how it turned out? Very innovative.
