My dad had a few made at the local high school shop class, the kids make em put them up and sell them for a reasonable price, then use the money for field trips, but its something you have to talk to the shop teacher about.. I think his was the ag class, The did a great job. He passed last year or I would get more information.. he lived near taylor Arkansas.. Pretty sure they where 100-150 each, and they also camo painted them, had tin roofs, and carpet floor, three shoot windows, rear access door, and a shelf un the front window. He put a swivel office chair in his.. It was very nice, I want to say maybe..8-12' high at the base. and tall enough to stand in. maybe 6x8, or so..
