Pizza and Peroni

Last year, due to an unwillingness to risk getting the wrong size/year/geeky detail, my lovely wife didn't get me a (main) 50th Birthday present - this year she made amends and then some with a pizza oven. And believe it or not this photo IS the intallation instructions, with current discussion focusing on how high it should be. I don't want a concrete tower block sitting outside the window all winter, so want to build it as low as possible, wifey worries about my back so doesn't want it too low. And eldest daughter's already invited friends round for a pizza party. So I'd better get cracking, and maybe this year's final Teas and Cakes will be pizza and Peroni...
