Is the kitchen price okay? Alternative manufacturer?

Thank you very much for your explanations. My parents also have Nobilia, I had one installed in a rental apartment and we are both very satisfied so far.
I also find our design appealing. Unfortunately, the slope is very steep, so the countertop is hardly usable. Maybe a few things can be placed there, but unfortunately it is not enough for a microwave, etc.

We therefore have to consider whether to choose the kitchen with a corpus height of 79cm, although I think that will drive the price up again, or if we should do without the drawer under the stove. Another option does not seem to exist with the handleless variant.

Why don't you raise the oven? There would be space next to the door for such a cabinet. And suddenly the drawer problem is solved. See photos.

The idea occurred to us as well. However, we do not want a continuous cabinet directly next to the door, so that it does not appear like a kind of "wall," but rather the area appears open and friendly.

The kitchen is installed. Unfortunately, we have a few defects. Regarding the scratches, the statement was "funny": they are located under the upper cabinets. Scratches in the non-visible area would not be a reason for a complaint, said management. Experts have already clarified that. Is that so? One cabinet will probably be replaced as a gesture of goodwill. The frayed areas will probably be sanded again to make it neat. I would have expected a different quality from Nobilia. Also, another photo of how the connection between the two countertops is solved. This also needs to be reworked.

that certainly happened more during assembly. The countertop was simply not mounted properly. Complain everything in writing and do not let them tell any stories on the phone.
