All RMZ houses have holes in the back, so you can add lights, if you wish. Also, the houses can be combined, you can add or subtract the number of floors. They are rather thin, so they do not occupy a lot of space. These three were 40 USD (w/ s&h). I think the colors on Chinese buildings (from Ali) are better, these are a bit too bright. But all of them are looking good on Plarail layouts.
