I needed a house model for a project and needed to draw a family home as fast as possible. To accomplish that, I chose a full scale that I could find good drawings and pictures of, and the choice fell on the Björkenäs house from Swedish Eksjöhus:
The original files are modeled so that the footprint of the house is 10cm wide. After modeling it, I realized it's fairly close to the N-scale (1:160). I have also scaled it up to H0-scale (1:87) and attached it in a ZIP-file.
The adaptation in the original files are done for 0,4mm nozzle, this is why the smallest details are 0,4mm wide. However, at least Slic3r still ignores many details so you need to click "detect thin walls" in the settings. This is especially needed for the windows.
The lower level wall is attached in two versions, one has a centering edge on the upper side intended to center the upper level. This is only relevant if you use the upper level without walls. The reason to use it is if you have the small version of the house and want lights that can illuminate both levels. If you want to use the upper level with walls, use the "Main Wall Flat Top" that you can print upside down.
The key to be able to print really tiny details is to position them horisontally. This is why the windows have been drawn as special parts, it's not primarily intended for multicolor prints (even if that's a nice consequence of course :) ).
Speaking of multicolor, this print does not need a multi-nozzle printer. The parts are dvided so you can print with different color with a standard printer using one color at a time.

Support is generally not needed in this print, however it depends on your printer.
