Underground bug out shelter anyone???

I love this idea, and I'm all for it.
I realize this is a house, but the ideas are amazing!!!

The advantage to living in an underground house like Don Hnatkos is the natural earth makes a wonderful insulating quilt for cutting energy consumption.

An underground house is also soundproof, weatherproof, largely fireproof, and doesn't require a lot of maintenance--no reshingling, painting, or cleaning eavestroughs.

On the downside, you do have to mow the roof once in a while.
