Build a house out of styrofoam?!
This thing is tiny and the bathroom doesn't seem to be connected to the rest. Also, the toilet drain appears to be the only utility.
The guest house or whatever is just foamboards glued together with stucco on both sides.
If it is stupid, but works?  The thumbnail is a lie, I don't have any idea what that structure is, but it looks nothing like what this lady made.
It definitely looks nicer.
Anyway, I really was trying to stay in grad school...
I just couldn't find the right tab...
No, not this one: He assembled a foil-faced foamboard cabin using foil tape and slept in it.

You've built sheds, what do you think?
You may've missed the 1960 movie en.wikipedia.org/wiki/The_L-Shaped_Room. Bad shape for usable space, but they were constrained by their roofing solution.
Someone should have whispered "running bond". What they have is a house of cards.
They never show how they finished the side of the roof that is one foot from the fence.

There are homes made with SIPS (structural insulation panel system). It's kind of the same idea, only it has plywood sandwiched around the insulation panels.
My favorite structural insulating material is AAC (aerated autoclave concrete). It's an insulation, it's pretty strong (when properly installed), and it's practically fireproof, waterproof, bug proof, mold proof etc.

If a fire ever got though their plaster skim coats, it would turn into napalm.

Concrete would turn into napalm? Am I missing something here?

Yes and no.
It was in reference to the first of the two videos. And it was hyperbolic. Styrofoam emits toxic vapors, it's polyurethane foam that's most hazardous:

Dami Lee did a pretty good explainer on Derinkuyu. but specifically at Underground Cities: Surviving DUNE's Deadliest Planet?t=600 there's twelve second on building a hay bale house and pouring concrete over it and then having a cow sacrifice the formwork.
It could be aerated hempcrete.
Styrofoam's precursors are tractor fuel

I'd rather be in a tent.
The Japanese build cheap disposable houses. Some of my first memories were of paper walls.

None of the 5,578 buildings built of AAC were destroyed in the Kobe 7.2 earthquake, and they even survived the subsequent fires.
