The stairs below the house don't fit, and the red thing on the roof (Which I assume is the chimney) doesn't fit as well. There are some chimney tiles in the tileset that you could use, provided my assumption was correct.
Also, mabye as something different, in the tileset, you can find windows for houses that are red (the curtains are closed).
Mabye you should put one or two of those in there?
Just a suggestion, but besides that, that level is completely superb.

Good job.
[Edit] I noticed that between the first and second floors, in between the windows, is the bottom house tile. In the tileset, there are tiles that can be used to correct that.
