Hi,
the splitting of buildings is often done with the terracer plugin. So, if there is one building with housenumbers 9-17, the mapper assumes that there are 5 single buildings (9,11,13,15,17) and uses the plugin to split the building.

But this can not explain your example, where building #9 is smaller than the others. 😉

Yes, that's why I chose this example. 😉
I noticed that many buildings were evenly split, but a lot of them seem to have "real" splitting that I cannot explain without cadastre information.
