Are these legal in Virginia? I looked at a house in NoVa the other day, custom build job, and found something very interesting. The house is still in construction, but in the finish out process. When they poured the concrete for the foundation, they accidentally poured it in the wrong place originally, so they left the original incorrect wall, and repoured the correct wall about 7 feet closer in. They used 1 foot thick concrete all the way around. Now the builder was smart enough to save this space for storage or whatever, so it's finished out. What's nice about it, was that it was 7 feet wide and 42 feet long, and straight. Perfect for a pistol range if you wanted it. He also built a wine cellar into the basement using 1 foot thick concrete for all the walls and ceiling, which I think would work better as a safe with a vault door on it.
Thoughts? Legality? Special zoning?
