I'm just going to make an interior on the canal house floor plan I found. It will not need to be attached to any house in particular. It can just be a stand-alone set.
How long are the sides of the houses?
Some of those look very modern to me, for some reason. I don't know enough about Dutch historical architecture to change it authentically.
Are there pictures anywhere of a house or two that are in the same state as they were historically?
Something to draw style from.
