Good morning everyone,

you really manage to scare someone :eek:, but well, it’s also a topic that is not exactly unimportant, so thanks for that!


I’ll come up with something regarding the terracing, I might have an idea, but of course it depends on the costs, the currently planned wall is already borderline expensive for us. Since the distance to the house is only about 3.5m, I would like to know what the ratio of the terrace (backwards and up, backwards and up…) would have to be in order to even be allowed to do it. No earthworks contractor could give us an answer here and I don’t want to annoy the building authority with questions again already, so I’ll wait a bit longer, even though they have been super relaxed and very communicative so far. And then a railing at the top will probably become mandatory, which we always wanted to avoid.


A soil survey is currently in progress, I hope to finally receive the last offer today.
The house hopefully won’t be a problem, due to the basement it will be built on the original plot, so the slope should not contribute to stability (I hope).

Rainwater must infiltrate on our property, which is why we are planning a cistern. Since the neighbor has already “complained” now, I probably don’t need to ask him about a discharge.

It still puzzles me how I could be held responsible here if I hire a specialist company to build the wall. I’m unfortunately not a lawyer, it simply doesn’t make sense to me with pure logic. That’s why I’m having it done by a specialist company and I’m not tinkering myself for four weeks with a rented excavator and 20 buddies just to worry about whether it will hold during every heavy rain throughout my life. But that is really a different topic.


The massive concrete wall is what the neighbor below proposed to the authority, but that is definitely out of the question due to cost. I don’t even want to know how much more expensive it is compared to the L-shaped stones (broken natural stones were already over 10% more expensive and are probably even worse statically).
Unfortunately, the neighbor doesn’t even answer the phone anymore (I have no idea what suddenly got into him, he was actually always quite nice and even though he received our building request, nothing regarding slope stabilization has been visible so far), but of course I’ll keep trying.

I really like your idea with the cistern, my thought was along the same lines, because the slope also gently goes into this corner (towards the east), maybe you could help me here.
The cistern will eventually fill up and overflow, now I have read that infiltration can also be planned there. Does that mean that the overflowing water then infiltrates around the cistern in a kind of gravel bed and is that sufficient to relieve the pressure on the wall and to call it “infiltration on our property”?
The problem with the water rushing off faster towards the south is not yet solved, it will presumably still shoot over the wall there (in case of heavy rain).

Do I understand correctly that you are filling in the cellar? Why is that?

The geologist/structural engineer came up with the idea that our 42° slope has to go until they realized that it was the natural hillside. Nobody voluntarily creates something like that as long as it can be avoided. I understand your neighbors. I couldn’t sleep with it and you have to maintain it. It’s a tough job and not for people with a fear of heights. Fall protection is necessary. Preferably a fence or being tied in. We have needed all of that already. Planting, besides water, structural stability, and reinforcement, is a big problem. Almost nothing grows there if it is a south-facing slope. With us only blackberries and some dry grasses.

Stop, stop before this gets out of hand... You can't understand our neighbor because no one has a plan yet on how it should be (he suddenly proposed to the office out of the blue to mandate a massive wall)...

What do you mean by [Auffüllung]?

I'm just modeling something to be able to represent it better, but it will take a little longer...

I'm on it...

We have the same thing at the back. There are houses below, but they are very far away and do not use the rear part (wild growth times 10).

Well, if the neighbor is a construction contractor himself, he probably has a hint of an idea about the challenges such a site brings. You - without wanting to step on your toes - don’t seem to be aware of the complexity of such a planning. I would also quickly have such a letter at the building authority.
