Construction defects? What do I have to accept?

I'm checking in again. I had no energy to justify myself. We are building 4 hours away by car. Daily supervision or similar is not possible. The roof truss has already been paid for, since the roof truss was on, as the neighbor told me. There is only a final inspection, no interim inspections. Nothing has been accepted so far. As soon as I realized that the roof truss did not fit like that, I informed the construction company. The construction company still does not find the matter serious.

You say that no matter what time consequences this has for us, we should stop the construction. For every further delay we pay 1500 euros rent and additionally about 1000 euros standby interest in addition to the normal interest and the full KfW installment. I cannot just ignore 2500 euros monthly additional burden. Once again chronologically regarding the roof truss: - Invoice for roof truss arrives, but roof truss is not there yet - Feedback to the construction company that payment will not be made because roof truss is not there. No reaction from construction company - i

- Neighbor reports that the roof truss is standing and sends pictures. We pay the invoice. - We drive to the house and notice that there is no dormer. - E-mail to the construction company + call to site manager. Site manager obviously does not know the difference between gable and dormer. But wants to take care of it - Construction company is on company vacation, so no reaction - Insisted on appointment with site manager - Site manager says it will be re-approved - Re-approval is still ongoing.

We also have no fine print in the contract.

The execution plans therefore cannot be executed.

No, he is simply the neighbor. We are taking an expert with us to the acceptance. It is also the case that the construction plans cannot be implemented because it is technically not possible. Misplanning by the architect. Only a dormer with tiny windows would be possible due to the knee wall height. The execution plans therefore cannot be carried out. The dormer cannot be realized without us losing a lot of light.

Going to a specialized lawyer will be unavoidable; and after that, the construction supervisor should also appear before the "final acceptance."
