After running a charcoal smoker, and a GOSM, I am totally hooked now. I have the wife convinced into letting me build a smoke house in the back yard. I talked to the fire dept to make sure there are no restrictions, or regulations against doing this in our city. They gave me the OK and told me the only thing was I had to invite them up for the maiden voyage. LOL So - with a custom home building background, and looking at lots of ideas here on the site. This is what I want to do. Please Please tell me you honest opinions and correct me if I am wrong about something. I probley will not build this til spring, and am totally in the planning stage right now. Dimensions - 4' wide X 4' deep X 8' tall on the front X 7' tall in the back. Foundation - Sitting on Cedar 4x4's on a concrete slab. For portability, Inside walls to be Oak or Cedar or Pine Planks Outside walls to be Cultured Stone Barn style door on the front with black Iron hinges. Fuel - Propane burner, or Nat gas if I can get it there. Also a 55 gallon drum or steel fire box sitting behind the house angling upward to the smokehouse. I would run double wall flu pipe from the box/drum to the smokehouse. This way I can use one of the heat sources or both if needed. Wall construction - Paneling or planks on the inside. Insulation in the middle of a 2x4 construction. Tyvek backwards to keep the smoke in. Durock on the outside of the box, then cultured stone on the exterior. With a metal roof. Digital and regular stats everywhere. Would like to figure out how to have a light on the inside and a flood mounted on the outside pointing twoard the barrell. Dampners would be in numerous locations, and probley have numerous racks, hooks, and bracing in the ceiling enough to support a hog, or hindquarter. So am I totally crazy? DO you think it will work? Any advice or input would be greatly appreciated. I am not sure on the insulation and tyvek or the 2x4 construction. I want it to look nice, and be very air tight. I live in Iowa and the temps here in the winter are a bastard. So any additional way of keeping the heat in and the cold out is a added bonus. Thanks for your help.
