I could probably post the windmill if I can find the files, it was a while ago, so I might have to dig a bit next time I'm on my old computer. I could post what I had for the town hall, but I had to make up a lot of the pieces, I just cut them out of a solid brown sheet so I don't really remember how I made most of them.
This is excellent! I've been wishing I could find some papercraft scenery for my blindbags to live in. This will do the trick! I know the contest is over, but I hope you consider adding even more buildings!
