Obtain a demolition order against yourself?

It is a matter for negotiation, we only know your side of the story, you have interests, apparently so does the neighbor. If a lawyer, then one who has good connections with the authorities. The authorities cannot run your business, but must act in a way that is best for the common good. So the demolition object must pose a real danger. Or it must be urban-planning desirable that something happens there and a danger is prevented. The best way is via balancing interests. Neighbor, what is yours, what is mine, where do we meet?

I have now been trying to reach a balance of interests for half a year. The neighbor has stated that he has absolutely no interest in his own property, except that he does not want to sell it. He cannot even use his property because only our side is developed and further development by the city is not approved.

And yes, there is actually a huge danger from the existing building; at the corner from the house to Stadl towards the street, there is a hole about 3m x 3m in size, and the slate roof is already hanging down. I will look for photos and upload them.

Here are a few pictures:

But... his interest is that you buy from him his inaccessible half so that you can trade. That would be the balance. I am your only buyer, you are my obstacle. We block each other. I give you the money that the Expert Committee of the district has determined for this location, we get the expert, I pay him, you accept his appraisal. Ok? Karsten

As I said, he does not want to sell, neither to me nor to anyone else.

How old is the guy?
