Well concrete is not waterproof (generally) so they are technically also using the form as waterproofing. It's pretty clever IMO but you'd need rebar at the very least for any structure worth building...

It seems like a high amount of complexity. Lots that can go wrong. I’ll take tyvek and wood :)

Concrete is also super bad for the environment. Wood is renewable and far easier to get locally.

Is concrete actually a good building material for homes? It doesn't seem like it'd be insulating, and you're definitely not getting internal plumbing/wiring. And concrete is actively bad for the environment. It all feels like the shipping container home -- seems great at a glance, but doesn't really pan out to be lived in.

Ikea style flatpacked prefabs still seems like a vastly better option to me.

There have been many variations on building houses with prefab forms, going all the way back to Edison. Works fine, but the result is a concrete box. The shell is not the big cost item in homes.

If you want a small, low-cost box structure, there are companies that will sell you one. Concrete.[1] Metal.[2] Steel frame with wood siding.[3]

Injection molded would probably mean the mold is reusable where in this case, it is not. Maybe injection filled?

Pneumatic casting?

Pneuma-Plastic Casting?... PPC.

It's got a nice ring to it. Don't you think?
