When I extend my wood working shop, I intend on doing just that. I will box off one small corner, insulate the devil out of it, put an electric base board heater in there, and have a sliding patio door face the range. Then all I have to do is keep the heat on low, and slide the door open when I want to shoot. I can leave my bench rest out there, range rods, and lots of other things. I think that's a great idea there John. Every one should have a place like that. Maybe an air conditioner for the summer heat days....
