Paving in exclusive use that also covers recessed balconies, how are the costs divided?

The recessed balconies are part of the apartments, they are not a structure in themselves and in any case they do not protrude from the facade of the building, but actually constitute a section of it. So the flat roof that serves as a roof for the apartments also performs the same function for the recessed balconies that are part of the apartments themselves. The modalities for the distribution of expenses are therefore those of Article 1126 of the Civil Code, according to which the expense is for one third to the owner of the exclusive use and for two thirds to the owners of the apartments to which the pavement acts as a cover. .
