How much additional cost according to the structural engineer's calculation?

Exactly. Moreover, it is an absolute waste of time to get an offer if you have already signed a contract with another provider. You can use that time more wisely and, as often recommended here, get in touch with a lawyer.

But, and 11ant has already written this as well... if you can't handle 20,000 EUR now, it won't be 140m² with a basement, but in the current situation (high construction costs, high interest rates), rather 140m² without a basement and with lots of own work... or only 120m², but without much own work...

I can tell you how I calculated:
The sample calculation said 420,000 EUR. I first increased some items to get 450,000 EUR, so the bank would lend us a little more money.
And then we also kept back a good 70,000 EUR from our own capital.
So our reserve was 100,000 EUR... and what can I say...

The house is built, we live in it... but the reserve is gone.
And we have no basement, especially not in earthquake zone 3, and we were able to use all our excavation on our own property. That's a lottery... if the soil is even slightly contaminated, then God have mercy on you...

stupid question but what if it was contaminated? and how do we find that out – based on this soil analysis where the landfills want?

But, and 11ant has already written this... if you can no longer manage 20,000 EUR now, it won’t be 140m² with a basement, but rather 140m² without a basement and with a lot of own work in the current situation (high construction costs, high interest rates)... or only 120m², but without much own work...

I can tell you how I calculated:
The sample calculation said 420,000 EUR. I first raised some items to make it 450,000 so the bank would lend us a bit more money.
And then we also held back a good 70,000 EUR from our equity.
Our reserve was therefore 100,000 EUR... and what can I say...

The house stands, we live in it... but the reserve is gone.
And we have no basement, especially not in earthquake zone 3, and we could use all of our excavation material completely on our property. That is a lottery... if the soil is even slightly contaminated, then God help you...

Apart from that, there is a contaminated sites register for the soil, where a contamination should be listed.

apart from that, there is an [altlastenkatater] for the soil, it should show a contamination there

It doesn't always have to be the old chemical factory or gas station.

Soil can also be naturally contaminated or, for example, mixed with construction debris (from other builders 50 years ago...). That makes it expensive.

Z0 (i.e. clean soil) is quickly exceeded.

And because you’re lucky when building anyway, even more and stricter parameters apply from 1.8.2023. The LAGA (e.g. Z0) will then be replaced by the Ersatzbaustoffverordnung. So if you commission an expert report/analysis, directly say whether the construction will take place before or after 1.8.

(And the experts are all helplessly overloaded (and overwhelmed) because of the changeover)

However, I do not see a contract partner on equal footing on the other side. To me, it seems like a company that is already on a con artist hunt.

From the few posts of the OP, I have the feeling that probably no questions were asked. And the general contractor probably just thought that they had informed themselves accordingly beforehand, as certainly some of the builders do. Of course, it can also be that it is such a con artist, but it can also be that the OP is not showing everything here. Every coin is known to have two sides :)

Do you mean terminal blocks?

Yes, of course.

But would the OP have understood that?

but please try not to be so condescending, as that usually achieves the opposite.

My experience that being smart means NOT equating the involvement of a lawyer with an intent to escalate is not meant to be condescending. I trust the expert to find the right tone.

and what does that roughly mean in terms of price if you reduce by 30 sqm?

Although I just have a brief comment. "Simply" reducing by 30 sqm also entails a (possibly expensive) chain reaction.

I meant that a house, budget-compliant under the new conditions, would be about 30 sqm smaller (perhaps five more or less). (From my point of view) it goes without saying that it would have to be a smaller model, because – as correctly noted – just trimming the previous design would not be a successful operation.
