I have a question concerning the meaning of the preposition over in this news article:
The sprawling townhouse has 6,800 square feet of space over five floors, including the ground level, which opens to a meticulously landscaped tiered garden in the back that can also be viewed from a Juliet balcony on the parlor floor.
I checked this dictionary and found definitions 9a and 9b under prepositions over:
9a: so as to cover the surface of (something)
9b: in every part of (a place)
It seems both definitions work well for the usage in the news article. What do native speakers think?
