Believe it or not my new shoot shack was my wife's idea. Inside dimension are 10x12ft. The front has two windows that open in front of the left or right hand shooting bench. Also there is a front porch and a deck for out door shooting. It's set up for summer or winter shooting with a good size air conditioner/heater unit. The only real draw back is my range is only about 30 yards. However I do have a place near by to shoot at a greater distances.
