Hi all. I'm working up a plan for a smokehouse and need some professional opinions. I'm gonna start on the dirt, build a box 3 or 4 feet square out of cinderblock or retaining wall brick, 1 and a half or 2 feet high. Line the bottom with a few inches of gravel and that will hold my coals. On top of that I'll build a small shack something like an outhouse out of 2x4s and untreated boards, maybe a tin roof, maybe just boards. Maybe I'll shingle it, maybe not. I'll have a draft in the bottom side and chimney in the top on the other side. Secure it to the brick with some concrete anchors and metal brackets. Then I might find some old oven racks to lay my meat on. I saw one guy who put insulation and drywall in his smoker. Is this necessary? I was hoping the outside boards would be enough... What do you think? Problems? Complaints? I take critisism freely so feel free to bash my idea. After all, if it won't work, why build it this way? Thanks!
