Terminate house construction contract? Wrong advice!?

With regard to additional costs for the house and especially the ancillary construction costs.

These are costs that occur independently of the general contractor, namely dependent on the property.

The contract itself is fine, only the advice from an experienced person was just terrible and there was lying until the cows came home,

But the seller is out - site manager etc. are other functionaries, maybe that helps a bit.

The problem last year was that we had already planned our desired house, but the final development plan was so restrictive that we had to completely redesign.

Oh, the rule should always be: first the plot, then the house planning.

Because of various things that were still missing and to level the terrain.

These are costs that occur independently of the general contractor, namely dependent on the property.

In summary: either get out of the contract with a contractual penalty or admit to yourselves that you made fundamental mistakes yourselves and the construction company cannot be held responsible for everything.

Thanks first of all to everyone! No, we did adjust the planning according to the development plan and the house price got somewhat more expensive. The calculated ancillary costs were borderline okay, but the actual ancillary costs are multiple times higher (however, these are items that were already known beforehand, like drainage, sewer connections, etc.). It was just sugarcoated so that we would sign the contract. The deputy managing director then said that he has contacts, but now he no longer takes care of it. We were just too naive. We had little time because I was going on an overseas mission two weeks later and that’s exactly why I go to a general contractor, to have someone with experience advise me. But unfortunately, that was nothing.

The cost risk for services included in the construction contract, however, is borne by the contractor. Provided that nothing has changed in the planning fundamentals.

Free termination at any time. 648 Building Code. Observe legal consequences (rebuttable legal presumption regarding the amount of expense reimbursement at 5%; it can therefore be more or less; issues of proof).

Termination for good cause would be better, 648a Building Code. Also here the crucial question of proof is whether this is sufficient.

The problem last year was that we had already planned our dream house, but the final development plan was so restrictive that we had to completely redesign (and that within 3 weeks).

That was in October last year, right? According to the old thread, you were still looking for a company back then? What happened in those 3/4 of a year that now suddenly you want to get out?

and in the process we wanted to distance ourselves from the preliminary contract and cancel it.

But?

The additional costs have risen from 40,000 to 70,000.

Additional construction costs are your issue, not the general contractor’s. The decisive influence on the additional construction costs is the lovely word "provided by the builder".

Go to a specialist lawyer and have the contract reviewed.
(It is usually easiest if your bank issues a letter stating that the financing (in the new amount) is not approved. But it depends on the contract)
