Sooo. The right building type for urban residential blocks with shops in the basement and the occasional business is building=apartments, if I understand that right. And to set the number of storeys, there is building:levels. Now: If I have a building with basement, intermediate plant, 6 storeys, attic and superattic, what do I put into levels? 6? 10? I think that might need some more detailed clarification…

According to the definition used by several 3D renderers, building:levels counts the number of floors of the building above ground (including the ground floor), but without levels in the roof.
So for building:levels you don’t count underground floors, and you don’t count the attic either. There is building:levels:underground for the former, and roof:levels for the latter.
So, in this drawing …
… you would count P and S for building:levels, K for building:levels:underground, and D for roof:levels.
Unfortunately, I don’t know what “intermediate plant” means.

Great, thanks, that clarifies it. “intermediate” was a wrong translation. They are called entrepiso in spanish, that would be mezzanine or entresol.

I would not count mezzanines into building storeys like wikipedia (http://en.wikipedia.org/wiki/Mezzanine) says.

Well, I am looking at the configuration on the other side of the street, which is one of the blocks I am editing. There you can see a line of windows of the entrepiso, which is clearly above ground level, and contains normal height office space, but part of the entrance level architecture and looking different from the upper floors. If you don’t know the label on the elevator button, you can’t really tell whether this is 1st upper floor or entrepiso. So for this type of entrepiso I think counting in the level would be appropriate, because it would match slightly better what a map user not familiar with the local architecture details sees while standing in front of the building.

Also, adjacent buildings may have same roof height, but different internal configurations, so they probably should be represented in 3D with objects of the same height.
