Hello,
I have to admit that we approached the house construction quite naively...
We have already signed the detailed construction plans, and now the construction company wants us to waive our right to special termination in writing – is that even legal?
Now to the main question: we signed a fixed price contract (turnkey), but the site manager said that the price might change again after the structural engineer's calculations???? I mean, we won’t make any more changes to the plans, and we have already budgeted with the bank based on the known price – is this normal? It feels like buying a pig in a poke!
Best regards

There were nearly 1000m3 (1300 cubic yards) of clay soil due to the slope, and the backfilling with new material was included as well. Clay soil is not really suitable for backfilling.... As a helpful note for the original poster: For the redesign from "without a basement" to "with a basement," the general contractor only charged 2500 euros. However, I doubt it will be just as affordable the other way around...

By the way, I can't find this model in HdH's current portfolio, only as a semi-detached house (6.13 x 10.67 m) (20.1 x 35 ft) (?).
What exactly did you request from them (as well as from the other two)? Actually, the Creativ Haus was still available from them at least last year. We did make some changes though, for example, a larger house but no balcony.

By the way, I suspect that the twenty thousand mentioned over the phone, and twice that amount on the invoice, might be roughly accurate ;-) That might be the case... we have an offer of 56 euros per cubic meter (0.035 cubic feet), but I don’t know how much that will end up being in total.

For example: 11 m * 11 m * 3 m = 363 m³ (12,818 ft³) * 56 euros = approximately 20,000 euros

You can quickly estimate that.
For example: 11m (36 ft) * 11m (36 ft) * 3m (10 ft) = 363 m³ (13,000 ft³) * 56 euros = about 20,000 euros The question remains whether the calculation is based on the volume of natural soil or the volume of dumped soil. A dump truck is full when loaded by dumping.
