As for air control, you could cob in a curved wall to fill in the gap below the grate, then cut a hole which could have a simple adjustable damper for those times you want things just to simmer. Something like a cob oven door but hinged or a slider plate if you want to get more fancy. Keep us updated as we all like pictures!
