Difficult to decide. Arguments in favour: Lowered kerb and the entrance is not obviously blocked. On the other hand, as a building owner, you probably have to assume that the driveway will not be kept free if you don't put up a sign (and even in this case there are often cars parking there). Therefore, I would assume that this pavings no longer serves as a driveway and would have rather not mapped it.

(In the context of the Berlin parking project, I am collecting information on such things here - see "Einfahrt": https://wiki.openstreetmap.org/wiki/User:Supaplex030/Street_parking:_How_to_map_a#Einfahrt)
