ᐅ Terrace Wall Adjacent to Neighbor – What Should We Consider?

Hello forum members,
We want to separate our terraces from the neighbor, who without our consent poured a concrete base on the property line, about 17.5cm (7 inches) wide, and built his terrace there. Now it is basically possible to build a wall right on the boundary, with a maximum thickness of 17cm (6.7 inches).
The wall will be 180cm (71 inches) high and 3m (10 feet) long. It will be anchored to the house. I don’t have more details at the moment.
My questions:
Is the wall too thin at 17 or 17.5cm (6.7 or 7 inches)?
What do we need to consider? Alternatively, we could build a proper wall only on our property, or place it partly on the boundary but mostly on our land, using 24cm (9.5 inches) wide bricks. I have zero experience—does anyone have advice? The whole wall will be rendered white.
Is 180cm (71 inches) a sufficient height? I would appreciate any tips.
I will send pictures tomorrow. We have an end-of-terrace house and want to separate our terrace from the neighbor’s. Now he has already built his terrace and laid the foundation for the wall. The foundation is about 17cm (6.7 inches) wide and exactly on the property line, so it lies partly on his and partly on our property. The wall is going to be built on this foundation. What should be considered in this case? I will gladly share pictures tomorrow—it’s too dark now.
Kind regards,

It is like a wall. According to section 906 of the Building Code, this can be considered an unreasonable disturbance to the neighbor – for example, due to the shadow it casts or its appearance.
Yes, your wall is unusual.
That’s right. As I said, it needs to have some distance from the shared fence. You can’t just lean it directly against the shared fence. Oh, now I understand. Yes, I will look for a different fence; it doesn’t have to be the one I posted. I’m considering a somewhat more “open” design that doesn’t look like a wall. Maybe a wooden fence or something else—I’ll check online for more ideas.
Of course, there needs to be some distance from the boundary fence, but I think I read somewhere that I don’t have to leave any distance for a boundary fence if it’s up to 180cm (6 feet) high.

Feel free to share your ideas with me, Keep the shared fence at 120cm (47 inches) high. Get already large bay laurels and plant them in front (I dislike these plants, but in your case, they actually make sense).
It’s thousands of dollars cheaper and will be reasonably dense within a year.

We have a large area How large? I would need to put up about 100m (330 feet) of fence to my neighbors if I wanted to.

How long? I would need to install about 100m (330 feet) of fence to my neighbors if I wanted to. I will look at some pictures tomorrow and in the next few days and see what ideas are around in the neighborhood. It’s hard for me to go down to 120cm (47 inches), but as I said, I’ll take a look.
We don’t have 100m (330 feet), that’s really a lot. It would be approx. hm, so to the neighbor with the terrace, about 10m (33 feet), on the other side the lot is empty, so 22m (72 feet), then 15m (50 feet) in front towards the street and 8m (26 feet) at the entrance beside the house. I’ll check tomorrow, I estimate about 50-60m (165-197 feet). I honestly don’t remember the exact length of our property anymore. When it comes to paying for the fence, I would also like to have a neighbor on the other side. If everyone agrees, you really save a lot. The plot belongs to the same owner from whom we bought our property. I have often thought about asking him if we could build the fence exactly on the boundary line, if he would contribute and then get the money from the buyer if he sells. However, I wasn’t sure if that would seem too bold, and who knows who will move in; I’d rather build on my own ground. I need to weigh this up, think it through, etc.

Honestly, I wonder why you haven’t discussed this with them yet?

Honestly, I wonder why you haven’t discussed this yet?So, the “neighbor” on the left owns a huge plot of land. You could even build three townhouses there. My garden around the corner is quite wide, about 8m or 10m (26ft or 33ft) from the house wall, I believe. In any case, he is a nice man who works for the city, though in a different state, at a building authority, and his wife does as well. They helped me a lot back then with the building permit / planning permission to get certain things approved, even though they are standard and common locally, but the authority here tends to be uncooperative. It turned out that the authority was quite annoyed because of Mr. Müller, who also causes trouble there. I settled many issues personally, and then everything became no problem. We had to raise the ground level by 2m (6.6ft) to reach street level for the construction. Our plot is 2m (6.6ft) higher than the neighbor’s land. We would have to stabilize the slope with retaining walls (L-shaped concrete blocks), or alternatively, we could raise his plot by about 1.5m (5ft), which would allow us to put up a fence without retaining walls. He gave me written permission for the filling, since his land will be raised when the building takes place, but we didn’t have enough soil left to fill (we were given some for free). I’m quite sure the neighbor won’t object to a 180cm (6ft) fence if I don’t make anything too conspicuous. He doesn’t live there, and generally, it’s in everyone’s interest to have privacy screening. It’s common here—everyone has one. The dispute with Mr. Müller is unnecessary and unjustified.
Well, anyway, since I have about 100 other construction issues to deal with, I wanted to handle some of those first, and only ask the others once I know what I want myself.
Privacy can also be achieved by carefully selecting plants. There is no need to build 180 to 200 cm (6 to 6.5 feet) high fences that look like prison barriers. Unfortunately, this is becoming more common and really spoils the streetscape. That is probably why your community has the regulation

that you mentioned yourself in post 49.
This means that in areas facing public spaces, such as the street and other open areas, you can build a fence, but you must plant vegetation all around it so that the fence eventually becomes hidden. Consequently, this also means that in these areas the fence must be set back some distance from the property boundary to allow room for suitable planting that will serve as a natural screen.
