Base plate incorrectly positioned

I would refrain from threats!

As I said, whether you want that or not, everyone has to decide for themselves. But I think I have read from you several times advising against lawsuits/lawyers. Are you afraid of lawyers?

I am here for a healthy balance ... there were at least 3 craftsmen who did not work properly for us, I cannot sue all 3 now .... But you just shouldn't put up with everything and if it ends up with a lawyer then only because someone was not willing to compromise

But you just can't let everything be done to you, and if it ends up with a lawyer, it's only because someone wasn't willing to compromise

That's exactly what I mean. If the shell builder constructs the foundation slab incorrectly, that bothers me, and the shell builder is not willing to compromise – of course I then go to a lawyer, because that's exactly what they are for. Especially in a situation where the legal situation is unclear (like here, at how many cm does it have to be corrected?) lawyers are there to clarify. It's also not about immediately suing the craftsmen. A lawyer contacts the company, explains legally why the customer insists on a foundation slab as shown in the plan, and sets a deadline. No craftsman in the world will get involved in a legal dispute in such a situation – that costs more money and nerves than simply correcting the slab within two days or reaching a compromise with the builder. You are still allowed to insist on your right, or in this case on an unclear right – that's all I want to say. It's not as if just because I involve a lawyer, everyone has to appear in court the next day.

But I think I have read from you more than once that you advised against lawsuits/lawyers. Are you afraid of lawyers?

No, certainly not afraid. But through my work, I have “touch points” in criminal law. Lawyers first earn their money by patiently writing letters. Whether they can achieve anything with it or not: first, there is just talking...
But what does this have to do with what I wrote here? It’s about weighing and proportionality in a dispute, and a lawyer is not the one to decide!

Weighing and proportionality in the dispute

Exactly. And if you were to live for the rest of your life in a house that was not built as you planned and approved by the state because the shell builder messed up and refuses to fix it, wouldn’t you try to have a lawyer resolve it?

It's not like just because I hire a lawyer, everyone has to appear in court the next day.

It's not like something happens immediately. As already said: first, if not ordered by the regulatory authority, there is a stop through the lawyer to continue building. Then a letter is written to the builder, ideally faxed/emailed. The builder has 10 days to respond. If then a malicious builder insists, time passes and the nerves of the property owners wear thin because nothing happens on the construction site during this time.

Exactly. And if you were to live for the rest of your life in a house that was not built as you planned and got approved by the state, because the shell builder messed up and does not want to fix it, wouldn't you try to have a lawyer handle that?

Stop. This is not about the house, it's about 20 cm on 4 meters. As already said: that may be annoying, but the OP has rather seen option 2 as the favorite.

It's always easy in a forum to insist on the law (in this case to post "option 1") when you are not in the same situation yourself and do not have to weigh things as the OP did here. Fortunately, they were able to agree or the builder ended up losing out.

Personally, I probably would have had a nice carport paid for me — on 3.80, of course.
