Thought about building a oven for a few years and finally made the committment and dug up the backyard, no turning back now. Planning to build a 42" Tuscan style. The foundation is done, more than likely over built. Purchasing cement blocks tomorrow. I found the Forno Bravo plans to be at times confusing. My foundation is 80" X 94" and at this time planning for the stand to be 5 blocks deep and 4 1/2 blocks wide which should give me enough room on the hearth slab. Not sure why the plans call for cutting blocks to 12 ". More questions then answers. Been given a deadline of Oct 8th for complete in time for my wife's 50 birthday bash. Pretty sure it's going to be Pizza Hut pizzas. Always open to input.
