here's an example, it's from 2001 in the port of Rotterdam and called parasite:
a building atop a building. This is not very common, but these cases do exist.

here's another building:
building:levels=1? or is it just a roof level and building:levels=0? Like these: https://media-cdn.holidaycheck.com/w_1280,h_720,c_fit,q_80/ugc/images/8854772a-b9a1-3711-8828-598092649a71

indeed some cases are better modeled with a min_height tag.

I'm all for min_height in this case. According to the wiki we should be tagging building:levels=n1+n2
n1=actual building levels
and n2=space between building and ground divided by height of these building levels
And this is already a benevolent interpretation of the wiki, you could also see n2 as "normal level height" or as height of nearby building parts. IMHO that's all insane (as is the idea to omit underground and particularly roof levels in the level count).

I wouldn't consider the tree a building part, although it's a part of the building. What do you do with a building atop a mountain, will the mountain become a building part?
Quite iconic also this structure by Kenzo Tange: https://i.pinimg.com/originals/33/0f/84/330f845c9bec3e1a3db5abc357a2528b.jpg
You could consider the single capsules buildings.
