ᐅ KfW 70 | Requirements for Basement Windows?

Thanks for all the responses! I never expected to get so many—I’m new here.
Sorry for my late reply.

@ypg: Yes, the developer! In our case, they represent the architect, structural engineer, and everything else. We are now trying to take over the site management ourselves. But the contract has been signed for over a year, so we are stuck with their “slow” (forgive the expression) way of working. A legal process would only drag things out further. So, we have no leverage to push things forward.

@Elina: At least double glazing. Our developer might try to cut costs at our expense.

I’ve taken out my energy certificate. Unfortunately, the data about the basement doesn’t tell me much. I’ll attach the page here. Can you make anything of it?

Hello,

Did you also purchase the land through them, so everything came from a single source?

But the contract was signed more than a year ago, and now we are stuck with their "slow" (forgive the expression) way of working. A lawsuit would probably only prolong the process. So we have no leverage to help us move forward.

If I were you, I would contact the local chamber of architects; they have mediators who can be very helpful in cases like this.

According to your attachment, your basement has no basement window wells.

Best regards, Bauexperte

There are only interior basement walls; the exterior basement wall is missing.
