Once you&amp;#x27;ve built a basement, you might as well put a house on the next floor up.&lt;p&gt;Modern insulation technology is very effective. It&amp;#x27;s much cheaper to put a lot of insulation in the above-ground portion of a house than to try to build the equivalent area entirely below the grade.&lt;p&gt;Building entirely below the surface without putting anything on top would be massively expensive compared to the same square footage in a traditional home, even if you accounted for equivalent insulation and cooling costs. It&amp;#x27;s not even close.</text></comment>

There are different water and ventilation concerns for these. An above ground home is pretty accessible for repairs, but these can be nearly impossible if the home is underground.</text></comment>
