Hello
You wrote that due to the long period until the approval of the shed, the building permit has expired. To discuss the further procedure, they will come for an on-site inspection. Since the shed was already accepted several years ago, I assumed it was an unfortunate phrasing. I thought it was only about the enclosure. When I called the building authority, I read between the lines that the files no longer clearly state what is now in place, what was accepted, and where the problem lies. A written solution, as I suggested, was categorically rejected. They insist on an on-site inspection. Well, that is the situation so far. The next step will be to study the letter that the authority is undoubtedly currently drafting. After that, the course of action will become clear. It seems to me that they want something from me, namely to complete their file. I can send you everything in copy. But for that, there needs to be a conversation and not the swinging of the bureaucratic club.
