Catch a 2-meter slope, L-shaped stones, dry wall or other ideas?

There are a whole range of possibilities. For example, about 15 houses in our street have a 2-3 meter high slope in the garden. What you do also depends, for example, on how you want to use the garden.

For example, we have three levels:
1st level with 50cm L-stones, which protrude about 40 cm above the garden level. On top, we placed a wide natural stone windowsill (about 40 cm deep and a total of 6 meters long - divided into one piece of 4 meters and one piece of 2 meters), so that you have a nice bench over several meters in length. Above that, two more levels (each about 60 cm step and then another 20 cm piled up), which in our case were planted with perennials and shrubs.
Other neighbors use the steps for vegetable cultivation, for example. Depending on the orientation (ours faces south), the vegetables grow especially well here.

We have a centrally located stairway with 15 cm steps, a total of 14 steps.

Therefore, I advise you to consider whether your primary goal is to have the lower part of the property as large as possible (for playing soccer, badminton, etc.) or whether you want to design the lower part smaller and thus make the steps useful for garden design. Personally, I would not find a 2-meter wall attractive.

I would definitely intercept in two stages there. That does cost you a bit of floor space, but at the same time creates a raised bed. Additionally, the planting in between visually reduces a lot of the height. I would generally always prefer a natural stone wall to a concrete wall, it just looks much nicer.

I would rather not just slope it off, that takes up a lot of space, is difficult to use, and hard to maintain. The wall + slope variant combines these disadvantages with the costs of a wall.

Thanks to you all in advance for the info and tips. :)

Maybe a basement floor. Unlikely that the plot slopes evenly and then suddenly drops off.
What did you submit with the application?
What does the development plan specify?
A structural engineer wouldn't be a luxury.
Has the area for the house and terrace already been filled?
Have load plate tests been conducted to check compaction?

There is no development plan, neighbors mostly have basements and then the basement exits at ground level - this was no longer financially feasible for us, so no basement floor.
In the application, the slope simply grades out at about 35°.
The basement is currently being filled and will then initially look like this so that everything is prepared for the foundation slab:
Garden side ___________/‾‾‾‾‾‾‾‾‾‾‾‾‾ House/street side.
So the garden is flat again and flush with the neighbors.

There are quite a few options. For example, about 15 houses on our street have a 2-3 meter high slope in the garden.
What you do also depends on how you want to use the garden.

For example, we have three levels:
1st level with 50cm L-shaped stones that protrude about 40 cm above garden level. On top we placed a wide natural stone window sill (about 40 cm deep and a total length of 6 meters—divided into one section of 4 meters and one of 2 meters), so you have a nice bench seat over several meters in length. Above that two more steps (each about 60 cm step and then another 20 cm raised with fill), which we planted with perennials and shrubs.
Other neighbors use the steps, for example, to grow vegetables. Depending on orientation (ours faces south), vegetables grow especially well here.

We centrally have a staircase with 15 cm steps, a total of 14 steps.

So I advise you to consider whether your primary goal is to have the lower part of the plot as large as possible (for playing football, badminton, etc.) or whether you want to make the lower part smaller and use the steps as garden design. Personally, I wouldn’t find a 2-meter wall attractive.

Three steps would certainly take some of the "heaviness" out of the whole thing. Are all three steps made of L-shaped stones or are the top two made from a different material?
I would be worried if the L-shaped stones are only 50 cm each that they would still be pushed away from the terrace—do you have no problems with that? If I understand correctly, your setup is roughly something like my attached cross-section here?
We had also planned a staircase, probably just inserted as stepping stones.
And to use the terraces facing south as beds would also be our plan :)

I would definitely catch that in two steps. That costs you a bit of ground area but at the same time creates a raised bed. Also, the planting in between visually reduces the height quite a bit. I would fundamentally always prefer a natural stone wall to a concrete wall—it just looks much nicer.

Simply sloping off I would rather avoid; that takes up a lot of space, is hard to use, and annoying to maintain. The wall + slope combination combines these disadvantages with the costs of a wall.

Two steps, so you mean three walls, like NatureSys also described?

Attached a quick visualization of what it might look like.

Two stages, do you mean with three walls, like NatureSys explained it?

With 3 walls, the problem is that you can hardly reach the middle area. So I would rather make it twice hip-high if that is possible.

Why don't you ask the one who planned that?
I would like to see the submission plan of the property.

I have so little to add to that that it actually wouldn't even come to 30 characters ;-)

Have a structural engineer take a look, since you have already filled in under the house.

And build a ramp for transports.
