A good idea I'm sure they will have some success with it, but the only thing they didn't advertise was the price. Going to be expensive. Aircrete is easy to make and use less expensive for the completed shell, when done it's yours. Unfortunately it's harder to get it permitted as they don't have any experience with it. A completed shell would cost one approx $2600

A wealthy guy built a "Zanadu House" in my town, years ago. They're constructed by inflating huge balloons on the ground and spraying them with a thick layer of foam concrete that hardens into what looks like string of connected igloos. Doors and windows are cut into the walls with a chain saw. They are cheap and quick to build and have an incredibly high insulation value.
Trouble is, this construction isn't even mentioned in the Building Inspector's BOCA manual and he hadn't the faintest ideal how to issue a building permit for it. The poor Town Assessor had no idea how to assign a tax value t it, either.
I’m a skeptic. Most of these alternative constructive methods tout “lower cost” as a key selling point but I’ve never seen one giving actual comparisons to conventional construction costs on a per square foot basis. The “build it yourself” alternatives certainly would be less cost as you aren’t paying labor costs to someone else for at least some of the basic construction. But framing and constructing the roof certainly is not a one man or two man job.

Structural insulated panels are used in houses with good results. Not much cheaper than typical balloon framing and insulating of a traditional building. The advantages are install time and an engineered building. They have the cutouts for doors and windows and channels for electrical wire, etc. The inspectors seem to like them as they are familiar with them. That said the cheapest part of a building is the framing. Trying to build a home yourself is extremely challenging unless you have some construction experience. The price listed in the earlier post is based on??? How many sq feet, what style of house, etc.
Something similar in Insulated Concrete Forms (ICF’S) which look remarkably like hollow Leggo’s. They started out as basement forms, but now go multi-story. I saw many of these during my career.

Where does the wiring and plumbing go ?
Looks like the blocks have a smooth inner surface.
Hey Jerry,
Are you kidding me ! I had trouble with Lincoln Logs when I was a kid !

Yes I was aware of that method also, and getting it permitted is a big problem for sure.
