I was wondering if anyone had experimented with any alternative designs (for tight spaces) like an oval design or perhaps a twin oven design (with a connection for one fire between the two) or maybe even a couple small ovens stacked vertically? Reason I ask is I don't have a lot of space for a huge circular oven, but I need more space for cooking 15" pizzas than just a 36" or 42" oven can handle...I guess what I'm saying is my kitchen has a lot more length than depth so what can I do (besides expand). I simply can't fit a 48" or bigger oven in there (all measurements are inside diameter - but I am factoring in overall size of hearth/stand). Ideas? Experiences? Photos? Advice?
