In my post Stigend suggests they should make a baker.
Here's a picture of a differene between a lean-to and a baker. (second last from the bottom...)
I was thinking of a real large one.
In the 70's when I was a kid we had one at the place where we constructed our family's summer cottage. It was there for two years I think (it was taken down for the winter but re-erected the next year). It was big enough for some twenty people to sleep under cosily.
