Also, I doubt the building regulations around underground structures is terribly well conceived. Especially in Oklahoma, where I imagine most underground "structures" are either basements, or serve as little more than storm shelters. Most houses are designed and built to the minimum regulatory standards. It's expensive to overbuild structures, so people aren't going to do it unless they have a very specific reason to do so. Without any regulatory framework, or a bunch of experience, it's hard to expect anyone to get it right. This house is not a basement, but it seems to be built like one. Basements have houses and roofs above them that serve to move water away from the structure and provide a source of dry, conditioned air from above ground.
