Not mine, but a friend of a friend deal. Basically a small shed, 5' wide, 2' deep, 6' tall. VERY well insulated. racks starting about 2 feet off the ground, and all the way up. Just an oven burner on the bottom, with a cast iron pan and handful of smoking pellets or whatever in the pan. It's more of a permanent structure than some would like, but this one is at a farmstead. Works well. Steel siding inside and out.
