The answer to the OP is obviously YES!
I built this over the first lockdown and used it many times since. It’s needing a door and a few tweeks but it was pretty cheap to build, and kind looks like a bothy!
It heats up pretty quick and holds heat well. I’m hoping to get a door made in the next few days which will be better for cooking with the day after and to keep the cat out! Flue could do with extending which should help draw, but considering, it’s not particularly smokey as it is.
I’ve got no pic of pizza unfortunately, but I’ll try to share the recipe I found online which has worked well for us.
