Garden wall 105m² up to 2.5m height as enclosure - which system?

hello everyone,

the title already describes my problem. our property needs a fence along a length of 75m to compensate for the slope of the land. on average we are at about 1.2 - 1.4m in height, at the highest point it is 2.5m. here, terracing would also be possible to reduce the height per wall

since the garden isn't huge and I don't want to lose much space due to a slope, in the end only a wall all around remains. but: made of what?

everything I could find about wall systems from kann, weserwaben, ehl, diephaus or kreher are concrete hollow blocks which are strongly limited in the maximum allowable height. but unfortunately not in price. I would prefer it the other way around. I am not willing to spend €20,000 just for the bare stones

with simple concrete formwork blocks and proper reinforcement inside I should surely manage the height. and price-wise that would be about €2,500 just for the stones. quite a difference...

does anyone of you have ideas, experience, or suggestions on how this could be implemented? it should somehow be cheap, durable and visually reasonably appealing.

thanks for your help!

Firstly, enclosing a mound is not a fence - a fence "secures" the mine-yours boundary of a property. Secondly, I have doubts whether the development plan allows such significant terrain modeling. And thirdly, development plans also have ideas about materials that limit the agony of choice. What is on the other side of the wall: a neighbor, the street, or the class enemy?

Thank you very much for the detailed explanation of the terms. If inspiration strikes me, I might adjust the first post sometime. But I think people understand what I need as it is

According to rumors, there are also areas where there is no development plan. If I’m not completely mistaken, I live in such an area... so the material and appearance don’t really matter. In the neighborhood, everything is all mixed up

Last but not least, the quite critical 2.50m height is neither a problem according to any development plan nor the building code since it faces the neighbor and we agree on it....

So if anyone, after the nitpicking about terminology and permissibility is hopefully over now, has a practically useful tip, I would be very happy

Thank you!

More than 1.8 meters fence height is not allowed without a building permit.

We built the entire thing ourselves over a length of 30 meters at the deepest point (2.20 meters) using hollow blocks.

I was the laborer, my buddy was the brain. We mixed the hollow blocks, reinforcement steel, and concrete ourselves because there were only two of us; it cost us €3,000 including €800 for my buddy over 3 days.

You can't lift L-shaped stones by muscle power beyond a certain height. 75 linear meters by a landscape gardener costs significantly more. You'd be looking more in the region of €20k.

But I think you can understand what I need anyway

Fences include hedges, fences, or certainly walls - but not those with earth mounds, especially not of such height.

According to rumors, there are also areas without a development plan. If I’m not completely mistaken, I live in one of those... therefore, the material and the appearance don’t matter at all. Everything in the neighborhood is all mixed up

Without a development plan, §34 and the respective state building regulations apply. Furthermore, design statutes or similar may apply to entire municipalities, thus covering areas beyond development plans or §34 zones.

since it is towards the neighbor and we agree....

Building encumbrances, to which the neighbor agrees, can exceed an (at least permit-free) allowed level, and neighborly agreement does not change that.

No one here wants to spoil the easy-going nature of things for you, but building law is simply not for Pippi Longstocking.

L stones cannot be lifted by muscle power beyond a certain height.

L stones and hollow stones have different applications. The widespread hope that an overdose of steel will cure everything helps very little.
