Dustbunnii, that would be cool, sort of like how they can change their interiors? Sometimes the interiors ended up looking terrible, though. I remember one had a dresser just out in the middle of the room. It looked bad.
On the other hand, since I'm the new king- I mean mayor- in town, I should have the nicest home anyway. B)
I also feel like it wouldn't be out of the question to decide on an overall theme for the villager's house, like a rustic or a castle theme or something like that, at least for the exteriors
