SUBSURFACE BUSINESS COMPLEXES: I found this on the web from clicking on a few links. Subsurface space. They have everything under there. Kansas does have it's share of tornadoes and this place would certainly eliminate the fear of injuries at work from a tornado. The photos are very convincing. This may become more and more common in the future. Scan down the page to the graphics that compare the large building on top of the ground to the subsurface structure. For years we have had underground storage facilities, subsurface homes, business complex basements, subways and underground tunnels in the downtown areas that people use to travel from one side of the street to another or even further. People are already conditioned to being under the ground. My surprise was the size this appears to be and the fact that nothing appears to be above ground.
