I love Graham's house it's super nerdy and cute!!!
Flurry. Her house is crazy cute with all the regal furniture! (this also isn't my screenshot)
Exterior wise I believe Skye's is my favorite that I've seen, just because of that shade of blue. Interior wise though I think Ankha's is pretty cool with the Egyptian theme. Not sure where she sleeps, but whatever. I like most of the villagers houses on the inside, though.
