Construction stop by authority and demanded repair

So slowly we simply no longer understand the world.

Well, at least I no longer understand the part of the world where you only get back in touch again today and still leave my inquiry from early April - although it is immediately before your reply - unanswered. As far as I can piece together from the fragments you communicate, the land belongs to you, so it is at least not a tax-risky property development model (unless you acquired the land from the planning office); however, the construction company probably secures its claims with an entry in the land register (?) This would indicate a model where there is a payment schedule for the construction according to which you are supposed to pay for the entire house upon completion? Unfortunately, you remain in the dark about what is meant by the change of the builder. The mere possibility of referring you to the construction site again suggests a property developer characteristic of your contracting party. Accordingly, it is also unclear here which part of the two-headed corporate network you should or could have addressed with what kind of defect notification. In the case of the property developer, namely not at all, because you would not be the builder but the customer, and you would lack both the authorization to raise defects and the right of access, which would practically enable you to ascertain the defects in the first place. Conclusion: even if you cannot receive legal advice from us here anyway, you should still be more transparent about what you are actually asking!

I also find it quite interesting that back then questions to you were not answered and now new questions are being asked based on nothing.

So langsam verstehen wir die Welt einfach nicht mehr.

I do not understand the whole construct of the ominous contracts.
