At first glance, when you drive up to what you think is Al Schwarz’s Monolithic Dome home in Ferris, Texas, what you see is a door, sticking up inside a concrete arch, that’s covered with rocks and surrounded by more rocks. “Is that the entrance?” you wonder. Once through that door, you go down a slate staircase that spirals over an aquarium and down into the main dome with living, dining and kitchen areas. You are underground — literally standing inside a hill — but if you hadn’t gone through that door and down those stairs, you wouldn’t know it. It’s comfortably cool and light inside this dome that’s inside of a hill — like being inside any quiet, nicely lighted, restful, Monolithic Dome home.
