This diy outdoor cob oven would be awesome to have in the back yard. It would be perfect for baking bread or making pizza. I love that it is so inexpensive to make and it looks very nice. Being made of cob you would probably have to make a new oven every few years but at the amount of savings over a concrete outdoor oven I think it would be worth it and to be able to bake bread and make pizza in the summer without heating the whole house would be great as well.
