Selling new construction after receiving funding / Wohnriester - possible?

Continuous noise disturbance that only bothers a single person. Stick to the facts. The problem is not with the transmitter but with a single receiver...

Aha....since when is a minimum number of affected people required? Where does it say that? And you decide who the problem is?

It is a typically German problem that people expect and partly demand peace and quiet. Here there is no compromise with quieter music. "Compromise" means no music at all.

This constant mention of the supposedly "typically German" thing really gets on my nerves. As if all Germans were the same, felt the same, and thought the same. Into the pigeonhole and shove it in. Well, then I am simply not typically German or maybe I am typical or something else. Always reaching for the stencil...... And if it is so terribly typical, then why do you live here? I have seen enough other things in life and live here voluntarily.

I have also tried passive-aggressive measures in times of acute anger.

In the end, this only harms yourself the most because deep down you don’t actually want to bother the other person. That doesn’t help and is rather a type of person I don’t want to have close to me. Moreover, such behavior would have no class and would be pathetic.

Then she should get treatment, and not try to change the whole world around her...

I’m sure you also often get annoyed by inappropriate and disturbing behavior from neighbors or fellow human beings, right?.....Have you therefore also already sought treatment? What is the current status? Incredible.....millions of armchair experts and now even psycho-diagnosticians. We Germans really can do everything!

I keep reading here again and again about the neighbor’s right to play their music in the garden. Where exactly does that stand, please? Any disturbing behavior that carries outside is to be avoided. I would never have my music so loud that the neighbor hears it, except in individual cases. Where exactly does one take this right from, which is written nowhere? Freedom ends at one’s own property fence, also the acoustic one. In a world full of selfie acrobats and egomaniacs, a quiet or peace-seeking person is quickly branded an idiot. Wow!
Courtrooms and law firms are packed; apparently, there really isn’t that much understanding for neighbors as is written here.
I can only agree 1000% with . Definitely address the problem clearly and directly and look for a permanently livable solution that the neighbor also gladly supports out of consideration.
If that fails, I would calmly but decisively reorient myself, and you will be amazed at what suddenly becomes possible. For many, this is unthinkable because change causes fear for them or they have never really lived it. We have undergone several drastic changes; if necessary, it was changed.
We could have continued living wonderfully here in [the Schlossgarten] but with unpleasant conditions, that’s all. So we decided to build anew. It’s no picnic but I would make all my changes the same way again.
If the neighbor is truly an ignorant person, you will have the problem again and again. Then it simply doesn’t fit; I would put my health and well-being above everything!
I have seen children who suffered so much from the noise level in their environment, which absolutely nobody cared about. They were branded as oddballs and the noise kept blaring.
Of course there are good living situations, you don’t need an acre, what nonsense. The current situation is simply not suitable for you/all of you; if it can’t be changed with the people involved, then you find something new; things like financing, grants, etc. can be arranged, they are not comparable to your health!!!

Look at your finances, what does your husband say when you talk about selling? Then you can see for yourself whether it feels right or not.

My husband said to me earlier: "okay, where are there still plots with fiber optic?" ;D
So he’s definitely on board. I know it bothers him less intensely than me, but we are a team and he wouldn’t want to keep a situation that wears me down like the current one. He’s known me for a long time, and normally I’m not running on empty like this.

What I don’t understand is why you haven’t inquired about the costs at the appropriate places. But you’re not asking in the right places here.

What are the appropriate places then? Do you mean now regarding subsidies etc. when selling? Or about soundproofing?
Regarding soundproofing, I’m not sure where a private individual can inquire about that.

With regard to selling and subsidies / selling and repurchasing, I just wanted to ask here about experiences. It can’t be that rare that someone sells a property they own and decides on a new one. Forums are there for such exchange of experience after all. I couldn’t have known that this would turn into an ethics discussion and psychoanalysis here. ;)

I keep reading here about the neighbor's right to play their music in the garden. Where is that stated, please?

That is a fact. Outside of the "quiet hours," I am allowed to listen to music at room volume on the terrace and in the garden. Honestly, I don't even know how anyone could come up with the idea that this is not the case? There is absolutely nothing to discuss about this. Of course, the original poster is free to acquire a sound level meter and keep a noise log. With that, she can then also "gladly" involve the police and the competent district court. The court then has to decide whether it is still at room volume and thus acceptable or not. Unfortunately, there seems to be no generally valid definition of "room volume" in this country. Honestly, I have my doubts that the neighbor's music is disproportionately loud here; otherwise, it would have already become known in the neighborhood, or someone would have already called the police. No, even the OP’s husband does not seem to be bothered by it. So there is much to suggest that this is a very individual problem.

Which federal state is it then? If it is not too far away, I can offer to go there on any Saturday and talk to the neighbor. I imagine that as the same (occasional listener of music in the garden) I might have access to them). It would be silly if you had to sell your house because of that, and after all, we are a family of home builders!!!

...

Oldenburg in Lower Saxony ... if I’m not mistaken.

It’s best if we all come :)
Although perhaps too many “cooks” could spoil the broth...
But I have also already thought about some kind of mediator.

I'm not sure where a private person can inquire about soundproofing.

First of all, just simply use Google. The alternative is to call all fence construction companies in the region. Ask specifically about experience with soundproofing, or if they can't help, then ask who they can recommend. Asking around a lot helps: friends, family, coworkers, craftsmen, etc. Someone surely knows someone. You could even play a bit dumb and call an acoustics specialist. They usually work on indoor spaces, but like the fence builders, they might be able to refer you.
