I am going to be starting my wood fired bread oven project. I live in pa. All of my research so far does not have a footer below the frost line even in cold climates. The structure will be approx. 5 x 8 feet built on a slab with 8" block as the base and the oven at working height. Most info says in cold climates to just put 2" insulation under the slab and it will be fine. Do I need to put a footer and foundation below the frost line or is that just total overkill?
thanks
