So lets see if I can get this too work. I'm still working on this - need to get the metal done by a welder

This is a shot of the oven straight on from below.

The main mass is the grill, and the oven is on the left - you can't see the opening in this pic. The whole thing had to be pretty high to get up to reasonable patio height, since I'm on the side of a hill. In order not to have something that looked like a stone skyscraper by the drive, I broke up the massing into 3 parts left to right, and broke up the height by building a retaining wall, then wood storage, then the functional bit. Poured around 6 yards of concrete in the slabs.

In 2 of the wood storage bays you can see ash traps, and the cleanouts from them - one for the grill, the other for the oven. Nice thing about the ash cleanouts is that they'll hold around 10 years or more of fires if my experience with my house fireplace works. And they are much neater - you can just dump the ash down without worrying about whether it is hot, or it flying into the air
