Property developers in NRW. Can anyone recommend good property developers?

Hello everyone. As mentioned above, we are looking for a reputable but affordable developer in the NRW area. Who can recommend a developer they have already built with? It should be a solid house. Thank you in advance.

Where in NRW is the construction supposed to take place? Not an unimportant piece of information, as regional providers might also be considered

And should it be a developer who brings the property directly?

No, we have the property.

Then you should stop searching for [Bauträger] immediately and instead look for [Generalübernehmer], [Generalunternehmer], and/or architects, depending on your preference.

[Bauträger] only build on their own plots and sell the house along with the land.
