I am going to build a smoke shack/house with an external fire box. I have the basic plan in mind. One question I have is about the height. For draft purposes you can make a smoke stack with a damper any height you want. Is there any pros or cons regarding the actual height of the building itself. Not counting the room for meat in the inside of the smokehouse itself. If you diffuse the smoke as it enters the smokehouse to all sides and front to back is there a limit to the width and depth that prevents adequate smoke or circulation of smoke inside the smoke house?
