Just thinking out loud as I don't really use modules a lot.
Could you make a module of just the apartment minus the slab and another of just the slab?
Then combine those modules and make another module of that for the complete apartment (you can have nested modules).
Now use the nested modules for all the other floors but use only the apartment only module for the ground floor and create a separate slab just for that?
