Something along those lines is the plan, however, our steps will follow the same line...
We will have different lengths of the steps, at the top near the house about 2 meters (i.e., a slab that is 2x2 meters) and then the length of the steps gradually decreases with the last step being 45 cm long.
There will be a total of 6 steps in height, and the step height will be 15 cm.
I have already started building the molds, and they are "overlapping" by about 15 cm over each other where I plan to bend the reinforcing mesh "deep inside" the step about 5 cm where concrete will fill in and about 10 cm for the "floating" part.
The molds will then be filled by a pump truck.

Since the steps will be 2 meters wide, I have some thoughts about the red box in the picture. At first, I thought I would just put a 95x45 beam there, but I'm unsure if I can remove it later...?
I've considered "pre-casting," but I'm worried that it won't look nice in the transition between "my" homemade concrete and the concrete from the station later...?
For recesses, a styrofoam board is usually used and removed after casting. Keeping it in place without a bottom to rest on can be tricky (it will be hanging in the air). It may leave a lot of debris on the concrete in the hole, but it won't be visible (just scrape out until the last chip). On the front edge underside, it can look ugly; perhaps a small triangular strip glued on the styrofoam to create a transition into the hole. No guarantees with the styrofoam, but maybe a concept that's used.
I get the feeling that it might be easiest to make loose slabs and lift them into place. Or possibly cast one step at a time so that it's possible to place a spacer. But in the first case, a crane truck is required and in the second, many trips with the concrete truck if you don't mix it yourself.

Yes, I also considered loose steps, but with 2.3–2.4 kg/liter concrete, a slab of 2*2 meters would weigh almost a ton at 10 cm thickness. As mentioned, this would require some sort of crane if you don't want to risk life and limb for all your friends.
But that's probably how they did it in the picture, and if you have the space to cast all the slabs at once, you could then lift them into place with a crane once they've cured.

Lifting the ladder into place is out of the question because no crane truck can reach (or I would need an enormous truck), and it would probably be quite an expensive solution...
I will try to cast "by hand" and fill the lower part of the ladder to then be able to lay on an S200 styrofoam before casting from a pump truck.
That way, it won't flow between the steps either, and I can start from the top (which makes it easier).
