Original building permit documents to the construction company?

I'm not saying that I like such a phrasing. I'm only repeating the contractor's reasoning because I found this wording odd. However, it didn't sound like access to the construction site is per se denied.

Either you can live with it or not! If you can't live with it and the contractor doesn't relent, then you have to find another contractor. Quite simple!

Hi,

The building permit went to the general contractor in the original, why not? We got it back later, with additions where necessary. For example, the drainage changed slightly during the construction phase.
The building permit is not a car registration document.... why are you concerned about that? How should they use it as leverage? Are you afraid they secretly change the plans again?

Transfer house rights? Yes and no. If it is your property and the contractor is a general contractor, it remains your property and you are allowed to enter it.
We had the right to enter the construction site at any time, always had a construction site key but had no authority over the craftsmen. Do they maybe mean something like that?

Best regards,
Andreas

First of all: what kind of contract do you have with the BU? Does the land belong to you? I assume so, since the builder is listed on the building permit, and they also receive the original. So in this case, you. Of course, the permit can be handed over, and must even be given to the BU, but why the original if a copy is sufficient. You are the owners of the permit. And the house will belong to whoever is listed in the land register, not the one who has the permit in hand. I assume you have somehow misunderstood the BU [emoji4]

You're an accountant, that says it all (sorry!!) I'm one myself and know this species.

Preferably wanting to recount the last cent and check everything

Try running things on a construction site, you won't be able to align anything with a ruler
