I wanted to share my experience of building a backyard brick oven. I researched (and talked with mates) on and off for quite a few years before getting to work on this project. There is a lot of detail on the internet and books with lots of design, construction and material options (confusing!). I finally settled on a simple design that was a mixture of ideas from various sources. Simple approach as I'm not a trades-person, so I went with a dome shaped oven out in the open to eliminate the need of a chimney. The dome is made from red clay bricks and has an inner diameter is 1.1 meters. The oven is insulated with four layers of perlite-cement mixture and a final outer layer of builder's render. I included two K-type thermocouples during the build so I can measure the floor and dome brick temperatures.
My oven was built mostly from second-hand materials and scrap for about $500 AUD, and was constructed in my spare time between Oct and Dec 2005. I use the oven for pizza days with friends, roasts and veggies on special occasions, and of course bread baking when a few mates also prepare dough to make the firing of the oven worthwhile.
I have placed a photo set of the construction approach at:
I hope this encourages other novices that may be thinking of a similar project. It wasn't as hard as I had envisaged and has given a tremendous amount of satisfaction and good times.
