Unfortunately, I can only agree with that from my own experience. We also have such a "sweetheart" as a neighbor who wanted to prevent our construction in a gap between buildings... At that time, we were nice to him, adjusted our planning, covered the costs for a fence (instead of sharing the costs as provided by neighborhood law), etc. Conclusion: he sued us for alleged damages to his house caused by us, and for years we had lawyer’s letters with demands in our mailbox. That cost us a lot of strength, even though he lost his cases. Even today, after almost 20 years, the relationship is still extremely bad. Today we regret our kindness back then; I would not give an inch anymore. What I want to say with this: unfortunately, there are troublemakers, and nothing helps with them—they only understand counterpressure. I hope for the OP that he has a better exemplar as a neighbor.I strongly advise ... TO BE METICULOUS about the correct construction execution and compliance with safety regulations. It is very likely that he will use every opportunity to enforce a construction stop. And that can be massively costly.
Can’t he cover the roof in his house, straighten the floor with the slants, and then build a flat roof (perhaps from the existing tiles)? Maybe he should talk to an architect or google whether that’s possible. Maybe he can “attach” himself to one or more of your companies and it will then be cheaper for both of you?Well, basically it’s his frustration about the restrictions in his own house and that now flat roofs are also allowed, which means the restrictions regarding size no longer apply. I would argue that a not insignificant amount of envy is involved here... Unfortunately.
