A small update from our side: The dilemma continues. We canceled the existing house for various reasons (outside, 1 room too few, heating problem, etc.) and had actually decided on the new build. Briefly: here over 80 semi-detached and terraced houses are to be built in a mixed-use area. In several phases. Now we wanted to get information about the developer and I came across a negative review and was able to contact the owner. The developer built 16 houses last year in a comparable town, also the same type of houses. There were massive problems with construction delays, unpaid craftsmen, and not least unfinished outdoor facilities. The owners had already been to a lawyer, etc. Apparently, he is not willing to negotiate. This is the review: Anyone who wants to know how construction projects managed by Mr. xy proceed is welcome to go to Bad K.. in the … There, 16 homeowners still have neither a street nor parking spaces a year after the planned completion, and partly not even paved entrances, terraces, or heat pumps. The lady sent me pictures and that is really the case. Now we have concerns that we will be living on a permanent construction site. The first construction phase is only supposed to be finished in 2 years from today, that is 20 houses. So 60 more are missing, only then are all streets and sidewalks supposed to be completed. In addition, there is forest (nature reserve) at the back of the site where they have practically relocated all the animals. Could there be problems with the groundwater here? What rights do we have? How can we protect ourselves from ending up in the same situation?
