Dividing floors into different number of apartments

Is it possible to divide the each floor of a particular building in different number of apartments?

I have no idea if this is possible or not.

Even googling it is not giving any help.

Well, your question really isn’t clear at all. What are you actually trying to build? What does “divide floors of buildings into apartments” actually mean ? Are you trying to highlight certain portions of a 3D building? Is this even related to Cesium?
