I have been following this thread since the beginning about a week ago. And I’m really scared about the time after moving in. I can only hope that Berliners are generally a bit more relaxed. Luckily, we have already gotten to know our future neighbors from the backyard property a little (shared property) and have done some handiwork together on the property (trees and bushes). So far, they seem super relaxed. But we have only heard the neighbors next door so far. Ultimately, humans are strange animals. But I do think the idea of introducing yourselves and offering cake or something as compensation to the neighbors before the construction begins is good. That way, the upcoming disturbance might be forgiven a bit more easily, and you don’t move in with such a big negative balance on the "goodwill" account.
