Building law help what can we do

Bordeaux red and F10ü is stated in the contract

The RAL colors starting with 2 are more yellowish, Bordeaux red would have a 4 in front, also contains more blue, and the 4s are not listed in the [Bebauungsplan].

Yes, but we wouldn't have built the house if we had known that beforehand. What can we do now? What rights do we have? The construction company made a mistake.

A BU should know the differences, but so should you, after all, you are present during the sampling. Legally, nothing can probably be done. Re-sampling is then common.

But we were told they are allowed

I find it interesting what all causes people not to want to build their house. Honestly, of course you want a certain roof color, but throw in the towel because of that? And you all could have read the development plan, especially if the roof is so important. It's like in the flat roof thread. There are clear sentences in the development plan and some always say "you can probably bend that"
