When the wife and I move out to where we aren't restricted by neighbors, we plan on building a similar sized building. We saw
something like this at the home and garden show and like the concept. Not sure of the price, but when concrete filled, it should be rather sturdy. And from what the guy was telling us, it's insulated quite well. We also saw some buildings that included a regular door, overhead door, and concrete work with rebar for about $25k. These were about the same size as what you got too. How much was yours if you don't mind saying?
