A Quick Wood Fired Oven

By some strange quirk of fate, the previous occupants, builders or some other lazy so and so left a sizeable stack of bricks, both new and unused and reclaimed, in the garden. I've used some to build a simple barbecue and will use others to make a short path. I had no idea, however, what to do with the rest. Now I know:

I lack the chimney liner, or anything similar, the builder of the example illustrated used for his 'chamber' and will try to build a corbelled roof instead, although I could use some stone blocks that are lying behind the shed.

I'll need to buy the wood though I'm shan't need much so it shouldn't be too costly.
