This building is based on a school and herder house from 1787 in Berlin-Marienfelde (Germany) by the carpenter Egeltraut from Teltow. It's split in two accommodation + tiny cowshed and an open sheep shed on the left. I found the plans here and decided to make it "real" again.
It has a very unique chimney construction where two separate chimneys combine to one in the attic. It's also very cramped in there since I had to squeeze stairs, fireplaces and all the small rooms from the original layout in there.
Feel free to visit it on medievalrealms.co.uk on the Northern Realms street. Blueprint is available in case someone is interested.
