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.
