Upper edge of finished floor exceeded by 10 cm by the construction company

Does the height of the CP also exceed the planned height? If you fill up the 10 cm, no one will notice. Your neighbor does not have your plan.

You can file the objection.

Is the house already standing?

I would have to take another close look at the carport. But according to my logic in my head, I would have to be 10 cm higher here, since the strip foundation has the same height as the one under the floor slab. The house is already standing, the finishing construction is starting now.

The house is already standing, the finishing construction starts now.

Then it is already too late for any proportionate intervention, and the incorrect height most likely belongs in the acceptance report (legal advice on the wording "does no harm").
