Years ago, helped my dad build his earth-sheltered home in Nebraska. Imho those are the bomb. Easy to build, cheap maintence, cheap utilities, tornorado proof, earth quake proof and can be well hidden. Got to have good solar orientation, excellent drainage system and good basic design. Iirc the heating cost for his first winter...heated to 72 degrees was under $100. It was designed for lots of light and he had his garden on the roof.
