From what I’ve studied, fully underground housing is more

expensive because of extra engineering requirements and

excavation expenses and possibly materials. According to one

study I read, if you have 6″ of concrete on top of house,

plus 8″ of styrofoam a few inches of small gravel and 6″ of soil, this is equivalent to 20′ of earth.

at https://www.larrydgray.net in my recommended books section I list

some underground house books that I have read.

at my blog https://blog.larrydgray.net I have an article on

green building and one on earthen construction. Both of those

should be interesting for you to read.

I am more in favor of above grade house, with berms on 3 sides

and earthen roof with heavy insulation and 6 to 8″ of earth and

sod.

Rob Roy has a some good books along these lines.
