I have had my eye on the Petite Properties line for a few years now and have them in my queued list of one-day orders. The raven's perch will probably be in the first order. Many of the buildings have an open back; in a sense they are dollhouses. Others, I think, have a finished back that can open. I really like the style of play that this affords, and was actually moving in that direction generally with buildings, or at least the ones where I had control over it. They cost a bit more than average, but they are 1:48 which works better for 32mm+ games like Malifaux and many kickstarter game figs, and I have read that they come with detailed instructions to mimic the stone and wood planking effects in the display models. That's worth a bit extra, I think.
The furniture line is also extensive. Absolutely perfect for Malifaux.
