Podest stair combination: platform stair and half-turn stair

I have found a staircase that I find interesting and that in a way combines a landing staircase and a half-winder staircase.

What dimensions from a bird's-eye view will this staircase have, assuming it is square and not, as in the picture, one half having fewer steps than the other half? What step depths and riser heights do you assume? (Single-family house, 2.5m room height) It is more of a calculation example, although unfortunately I don't know how to calculate it.

What do you generally think about the staircase?

Thank you.

That seems to me a simply demonstrated illustration of a plain normal double-wound staircase with a poor tool. I don't see any landing. Slanted stair treads get wider on the outside because they rotate around a central point. In that sense, the steps are not landings, even if the tool suggests otherwise to you. Stair treads should not look interesting, but function with low risk of accidents. There are standard or minimum measurements for that, e.g. 19/26: 19 cm height of a step to 26 cm tread depth.

Too little information.
Floor height? (Ceiling height is not sufficient)
Stair width?
DIN compliant?
Should there be a railing between the steps?

What do you generally think about the staircase?

I wouldn't recommend it; the tread depth is wider in the middle of the stairs than in the rest. Better to only split the landing in the middle.

Do you have a plan where the staircase is supposed to go?

I would not recommend it, the tread width is wider in the middle of the staircase than in the rest. Then rather split the landing only in the middle. Do you have a plan where the staircase is supposed to go?

Generally, I say "this looks like a design flaw."

Not nice and also rather impractical.
