Detailed the building and its parts.

On the southwest side the parking garage's topmost level's height overlaps the height of two levels on the apartments there. If someone is willing to do it, the heights can be defined on the parts. But I think this is good enough for now. 

I marked a fixme on one part, as I couldn't verify the amount of levels on it from the street photos. It can be seen by finding elements with fixme tags.
