Is a stair floor plan 2x1/4 spiraled + landing possible with a maximum of 2.4x2.4m?

I played around with it again last night, and the following came out, which I basically like and which would also fit in terms of dimensions:

16
18.44/26, three-run:
1. 5 steps, then first landing as step 6,
2. 2 steps, then second landing as step 9
3. 6 steps, then upper floor as step 16

Do you think this could work? I definitely want to check if I can manage a non-spiral one before I finally focus on a spiral one.

In your headline you write about 2.4 x 2.4. that is initially not enough for a landing staircase for a normal room height, and if so then very tight (felt like not a proper landing) So rather for a normal 2-turn staircase. A landing requires at least the space of 2 x the width of the staircase.

Since I cannot open your link, nor can I imagine what kind of staircase you mean, because logically landings are already ruled out and I also cannot fit your specifications into the available space, it would be helpful to directly post a picture or drawing here. Did you ignore my link?

Best regards in brief

Here is the staircase

No, I did not ignore your link, the staircase has dimensions of 2.42m x 2.77m, so it has grown significantly on the upper floor, only the width has remained roughly the same. That should also be within the dimensions listed as minimum in your link.

I have to figure out today how I can upload a picture here.

What kind of staircase would you like to have? Wood, cantilevered? Steel stringer or concrete? Keep in mind that a rough construction dimension does not mean the final dimension, and a free-standing wood or steel stringer staircase also needs installation space, and the stringers do not necessarily have to be directly against the wall. Are you still in the personal initial planning phase?

We would like a concrete staircase. The tread should be covered with wood (parquet like on the floor), the visible front side should remain raw concrete. The architect's design is more or less finalized; a half-turn staircase is planned. However, we don't really like the spiral design, so I started looking for alternatives that we like. It turned out that a staircase with a landing and straight steps would be nice. The example above is my attempt to fit straight steps and a landing with comfortable measurements into a not too large space.

We are already in the approval planning phase; the staircase is actually the last point that we are not entirely satisfied with.

Is there anything against such a staircase with these dimensions made of concrete? Is it a problem that I have more steps at the top than planned at the bottom? Upstairs we simply have more space lengthwise than on the ground floor.
