Is that a Styrofoam wall?

I think that's the really interesting part of this video. The spray on stucco-like material is neat, but the whole house is made of styrofoam and the wire reinforcement is on the outside. They're clearly going to build this up in a number of layers. I've never seen that before.

If it were me, I would spray Gunite then plaster same way swimming pools are made

One thing I like about using the EPS panels and wire mesh is the insulation factor coupled with the reduced thermal transfer

10:28 video comparing this method to precast wall construction from a person in Kenya who seems to have some experience with both. It's worth watching if interested in it.
