Definition of fences/enclosures

Anyone who wants to take a look at the BauPlan (Es lohnt sich) is welcome to do so. Simply enter "Wohnen am Mühlenbergesee" on Google. I have already heard from many that this is one of the most common development plans regarding construction and enclosures.

Arguing about the enclosure will not help you if your real goal is to reverse the embankment. Aside from the fact that everyone will hate you for it, the first step is to go to the authorities. I also assume they piled up soil to have a level plot and not one that slopes to the side – such a thing is really difficult to use.

Those who piled up soil are hated. The authorities have been contacted from all sides, but no one really feels responsible and keeps passing the buck. Authority --> Engineers --> City --> Building Inspectorate --> Local Council --> Seller --> ... The matter is a bit deadlocked here. For some, the opposite property is as high as the neighbor’s roof eaves. I don’t think that’s the purpose of things.

A embankment and its retention, e.g. with L-bricks, has nothing to do with a [Einfriedung].

After I saw the plan, I understand the problem even less. Who borders whom there and who has built up? To the "rear" towards A and B there is no problem because B does not belong to any private builder, so it is about the neighbor directly next door? That confuses me because this V-arrangement then plays no role at all, but you made an effort to describe it in words.

Height restrictions exist in the form of specifications for the number of floors in combination with ridge heights and the reference point of the average height of the adjacent traffic area. That is all quite clear. At no point do I see anything that would prevent the neighbor's buildup within this framework. For rules regarding buildups, you look at the neighborhood law of your federal state.

If anyone, for example for aesthetic reasons, intended to prohibit buildups, they failed to do so. Bad luck for those who find this unaesthetic and assumed it was regulated. Although, their own fault, the plan is from 2006, plenty of time to notice the absence of such a regulation.
In my opinion, the plan is not that complicated either. It may be complex due to the different areas and the associated individual regulations. Anyone building a house there can simply ignore a lot because it does not apply to their own area.

After I saw the plan, I understand the problem even less. Who borders whom there and who has raised a mound? There is no problem "to the back" towards A and B because B does not belong to a private builder, so is it about the neighbor directly next door?

Yes! The areas B belong to us as builders. We are just not allowed to fence them. That’s why I said the development plan is fun to read.

Anyone building a house there can simply ignore a lot, because it does not apply to their own area.

And precisely because area B, contrary to your assumption, belongs to the respective builders, it cannot be ignored.

To come back to the complexity of the development plan once again. Since I had to explain it again now, you can see that it is indeed somewhat more complex than assumed.

You had to explain it because area B is not clearly assigned to the residential building plots. This should result from the marketing plan or the parceling. But well, everyone is supposed to keep a piece of grassland behind their enclosure. The municipality probably only thought of this later, to save the maintenance costs in the municipal treasury.

However, the statements regarding the enclosure are still no different. There are no rules for embankments (only in the area of the power line). In addition, a retaining wall is, in my opinion, not an enclosure.

The fact that enclosures are not permitted in B presumably has the background that B is to be maintained as a large green area. They are not to be used as private gardens. Here, it is solely about the municipality not incurring any costs for the area.
Embankments in B, which are then retained, of course do not serve this purpose. The meadow then looks like a certain memorial in Berlin. But the municipality simply failed to establish rules.
