I never thought about selling them, might have to look into what it actually cost with labor. Its 4 ft wide about 8 ft tall. We do have one that is about 6ft off the ground; we mounted it on top of a gas tank stand and anchored it to the ground. Another one that we have used to be a hog farmers feed grain bin that is about 10ft tall and 5ft wide, we just cut square windows into it and put sliding Plexiglas windows in.
looks like a nice place to hunt from!
is the wood treated or do you paint them
