Building with a general contractor - claim for additional costs shortly before the start of construction

And what does it look like when the price for the house is notarized by a notarial purchase contract? As a customer, you should be quite well protected against price increases, right?

What is notarized is not a price, but a contract. The price is a component of the contract – just like the conditions that can still influence the price after the contract is concluded. The notary does not provide you with price protection. However, it is their task to ensure that the contracting parties understand the contract. If there are too many questions about understanding at the signing appointment, they will not notarize it.

However, in that case, you do not build with a general contractor, but with a developer who sells you the land along with the house. Otherwise, a notarized contract does not make a general contractor contract better or worse - but much more expensive (assuming you can even find a general contractor who wants to do something like that).

Hello A notary does not review a construction contract. It is more about ownership conditions. These must be notarized. Ergo, with a price increase, you have no security at all. You probably have a contract, and it is binding for both parties. We do not know what kind of contract you have.

The question about the notarized purchase agreement was asked purely out of interest. I have an offer for the construction sum and a contract for work without a price escalation clause.

And handling such matters before a notary would be unusual - except in the case of a disguised developer deal. However, there would be no price increases just because the finished work cannot be handed over at the notary appointment.

Good day, perhaps something regarding the previous discussion. We have concluded a unit price contract with our shell builder. The contract stated that the prices remain unchanged until the complete execution of all services and that there are no material price or wage price changes. VOB B and C are part of this contract. We are now supposed to pay €5000 more in material costs, is this legally permissible? We have already paid €4000 of this in an interim payment because we thought we were obligated to bear the additional costs; is that the case or is there a possibility to recover the money or at least offset the difference on the next invoice?
