Your houses reminded me a bit of it  (if they're free, I'd love a download of these once you make them available).  I bet there are other people out there who would agree with me on this suggestion:

Yubaba's Bath House from the movie "Spirited Away".  If you're not familiar and you like Disney in any way, you need to see it. :c)  But THAT would be just an awesome model to see, or at least something inspired by it.   Here's a picture of the bath house front:

Interesting idea eh?
