New window lintels on the ground floor are too low.

In which rooms are the windows? Are there rooms that have both - that is floor-to-ceiling elements and regular windows? Proportionality aside - I somewhat agree with andi... it would really bother me; if it’s now in the guest WC and utility room maybe not so much.

Utility room, guest bathroom, kitchen, and living room. In the living room there are both, that is regular windows and floor-to-ceiling ones.

Hi,

We are not swinging a club. The plans have already been checked and are correct. The shell builder screwed up and the site manager apparently did not notice or did not take our concerns seriously.

then the matter is clear. They should change it and that's it.
All (hopefully penalized) completion and move-in dates of course remain unchanged.

Best regards,

Andreas

Utility room, guest bathroom, kitchen and living room. In the living room there are both, normal windows and floor-to-ceiling ones.

Without knowing the plans and the floor plan:
In the utility room and guest bathroom, one could possibly agree to a reduction if it does not ruin the view of the house from the outside.
In the kitchen it is a matter of belief, in the living room I would certainly insist on a change.

Kind regards,

Andreas

Hi, why should that not be an option? If the windows were correctly marked in the construction plans, they will first deliver them accordingly. Done.

For us, it is not an option because there will be a time problem.

If the site manager notices this too late, the additional costs are their problem, not yours.

I agree with that.

The timeline will become problematic, this is a bigger issue that will certainly delay the move-in by several weeks. If you are under time pressure and the construction company knows that, they will try to play for time.

Correct, and as confirmed above, that is exactly how it is. There is a fixed handover date on which our entire planning is based. The general contractor knows this and it has been communicated as such.

If you want to agree on a financial compensation: consider how high the reimbursement would have to be for you to be happy with it for the next 40 years. €500 compensation is quickly forgotten, but you will look at the windows that are too low for the rest of your days. Many greetings, Andreas

Also correct. Only I do not believe that this is (just) about a symbolic €500. Therefore, my initial question was who can answer that approximately accurately. The core question is: what does this conversion / defect rectification cost the general contractor?

If it already bothers you now, you certainly won't be happy with a compensatory payment either. You will obviously see the defect every day. A correction is certainly doable.

I have not made any judgment about it so far, my primary concern is my posed question.

You will obviously see the defect every day. A correction is certainly possible.

Both yes, but it still doesn't answer my initial question.
