What do you think about these cheap underground houses ?

Covering something in sob doesn't make it underground in my world.

Those look like plastic septic tanks cut in half and set upside down. They'd hold up some dirt and sod but probably not much more. Some of the pictures show grades that just aren't possible. The first rain would wash away a lot of the dirt covering the shell. Grass roots can't stop erosion on a 144 pitch.

I like the shotcrete idea but I bet those walls would cave in application.
