Build a terraced end house with an additional unit (GÜ) on your own

For example, I wouldn’t care about a crane either if it’s not usable, no matter why, he’ll just have to come up with something else. It’s not your problem but his who carries what where. [...] If you’re lucky, he’ll run out of steam on the way out and you’ll still get a decent neighbor if the corresponding deadlines are missed,

Honestly: from my point of view, the best solution would seriously be if at the head of the property there were three visitor parking spaces and then the green area "Bürgermeister-Dummkopf-Platz". Plan B on my wish list would be for the dim-witted neighbor to build exactly the house he is rightfully allowed to build without risk, then get divorced soon after and in the course of the partition auction the property would fall into the hands of a pleasant fellow.

After the phone call with our GÜ, he possibly sees the stability of our house endangered, after our foundation was completely excavated - therefore, together with our GÜ, we have arranged an on-site appointment with a soil expert, who must provide an assessment as to whether there is actually a need for action.

Normally, according to the GÜ, the foundation should have remained 20-30cm in the "sand".

Fortunately, the stability of the house is given. However, the soil expert says that the foundation must be frost-proof wrapped with some sqm of earth. So the neighbor can start working first. However, there is again trouble programmed regarding the cost coverage.

And our [GÜ] is currently no longer able to carry out the underpinning due to possible warranty claims - understandably.

... first of all, I think it’s really nice that you keep us updated here. I believe there are a lot of users here who would like to know how this story will eventually end.

I can absolutely understand your GÜ and with the current workload, it will surely be more than difficult for your neighbor to find a contractor who will take the risk. I fully agree with you, after the delays it can only be up to you and the advice of your experts. And definitely sign up big with ... for the mayor’s position.

I wish you strong nerves :)

[LUCKILY, the stability of the house is given. However, the soil expert says that the foundation must be frost-proof wrapped with a few square meters of soil. So the neighbor can start working first. However, trouble regarding cost coverage is also pre-programmed here.]

You should, apart from the fact that the cause should pay for it, possibly also "look around" yourself to have someone else carry this out. Would your GÜ possibly do this? Because in that case, the protection of my property would be more important to me at first, so that I would otherwise pay for it myself.

That the GÜ is not eager to do it anymore is understandable. Because knowing the background, I probably wouldn’t work with the neighbor anymore either, even if your GÜ is usually very well disposed towards you. He will also weigh it for himself that trouble could possibly arise there. Once directly and then possibly later, if there should be problems and it should be blamed on the underpinning. The question is of course what you have to allow according to the law? Depending on the federal state and neighbor law, I believe you cannot "prevent" the underpinning.

From my point of view, no. Winter is coming, I would see the time as ripe for an urgent application for an injunction that the neighbor must cover the bare tooth sockets of your foundation again. The colleague "referee in robe" should be asked to send the foul player off the field. I would not refrain from the knockout shot here.
