The design is based off directions for a backyard pizza oven found on You Tube, with added angle iron structure for more stability. Wonderboard is placed on saw horses for the base. Then one layer of 12 fire bricks make up the bed of the oven. Then courses of ordinary red clay bricks, not cement brick , are built up with angle irons to hold everything in place.
Courses across the top are supported by angle irons. Extra pieces of wonderboard serve as wind screens, a top, and a door.
