As far as I have read here, no one has a concrete solution ready for me either.
Yes.
Make yourself visible and make it easy for people to welcome you.
First, turn to the politicians of your local council. Try diplomatically to find out why no one except Peter has voted in favor and the rest abstained.
If they grant you a building obligation or would even be willing to swap a part of a plot section, you could build without a development plan.
Try to arrange that with the neighbor.
The neighbors to the west exchange a narrow strip within the zoning area for a large area in the southwest of their property. The building project moves 20m closer to the street, which makes the access more cost-effective.
No, I expect from a forum that someone can give me tips or advice whether there are still chances here or not.
There have already been some. If you don’t understand them, ask. If you don’t recognize them, I have no solution.
However, the advice also depends on the input. And from here it looks like this: Four years ago, an informal written request was submitted to the mayor to develop a plot. The mayor then commissioned the municipal administration to take care of the matter. An employee of the municipal administration called and advised to stay away from the council meetings, be patient, and buy the narrow plot. And about a year ago, someone from the municipality called and said that the council had voted against the request. Since then nothing has happened except that the dispute with the neighbor has escalated.
Hopefully, you realize yourself that some crucial facts are missing here. This is evident on one hand because this does not correspond to usual administrative procedures, and on the other hand by little snippets from you:
or even an invoice from the municipality
If you wonder about this, someone must have talked to you about costs and their assumption or even signed a contract.
but found it strange
What exactly was strange?

What exactly was set up?
and a fence that we erected lawfully
Do you know the fencing regulations under neighbor law? They are not that simple in your property constellation.
just because something doesn’t suit him
In #'1 it was still
just because someone on the council was not in the mood at the time
By the way, top lawyers also did nothing but wait
Who hired them for what and in which fields do they have experience?
I wanted to be that clever and protect myself there as well.
Protect yourself from what?
the building plan
So someone has mentioned that something else besides the application must be approved.
And I also don’t think he has such good connections to the other residents there.
He doesn’t need to. It is enough to have the connection to one council member – at least it is not unlikely that his appeal led to the change from the unanimous resolution for the development plan in 2017 to the unanimous (here literally, as all others abstained) rejection.
There is something strange here. And yes, not only with you. It already starts with the missing initial drafts in the council information system, goes through missing annexes with the appraisal results, and unexplained changes of mind by council members, up to cross-party abstentions (6 of 7 voting members!).
