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

The flight is interrupted by a landing, and the walking flow is not even. With you, this happens twice. In addition, you have a different number of steps in each staircase section. Landings and irregularities increase the risk of accidents. So with you, it’s doubled.

I would advise against a landing staircase or... changing the floor plan due to a different staircase shape. But then you basically start almost from scratch again, since I assume your stairwell is justified and cannot just be widened easily.

Mit halbgewendelt meinst du aber eigentlich eine 2x 1/4 gewendelte oder?

It is called a three-flight U-shaped staircase and is double winding or 2/4 winding or, as Robin says, 2 x 1/4. I googled it once.

By the way, the staircase shape is more common in medical practices, hotels, schools, or public buildings, as it - if properly built - requires a lot of space (because of the stairwell). There is then also a reasonable number of steps in the middle.

In a single-family house, I assume it is avoided because two steps, then 3 or 5, are dangerous in everyday routine.

Google spits out numerous different terms here.

I meant a half-turn staircase, at least that's what comes up when I enter "halbgewendelt" in Google.

/Edit: On the architect's drawing, it is a 2 x 1/4 turn staircase. The top and bottom steps are straight.

I hear that you would still prefer a 2 x 1/4 turn with 16 STG 18.44/26 and design it with a 1m raw construction width?!

I have my quite own way of thinking about stairs, for me they are a vehicle from top to bottom and vice versa. I personally would pay more attention to the materials.

Personally, I don't like the 2 landings. Normal landing stairs remind me more of apartment buildings, but I could also have that exclusively.

So my alternative is now a 2 x 1/4 spiral staircase with the following data:

16 RISERS 18.44/25.94
Step measure: 62.82cm
Staircase width rough construction: 100cm
Floor plan: 240cmx200cm

Is there any objection to this staircase?

And why exactly am I walking there with a limp?

That has already been well explained

It doesn't have to be bumpy, or rather, every staircase that interrupts the step sequence is actually bumpy (ours too). I once read something that basically it is best to climb the stairs without interruptions and that there tend to be fewer accidents without landings, etc.

No one in your family will have exactly 63 cm step length (or only by chance). One subconsciously adjusts to the difference from the "norm" while using the first steps. If the step length then changes in between – especially here because the landing length is not an integer multiple of the step length – then climbing the stairs requires attention (again subconsciously, but still needs computing power in the brain), which increases the risk of falling.

Unfortunately, your posts do not contribute to finding a solution.

I am modest and also content with contributions aimed at avoiding errors

Can you make a suggestion or is your opinion that it has to be a half-turn staircase? What would be a reasonable staircase with straight steps in terms of dimensions?

I don’t know your floor plan, from which alone I cannot say for sure whether I would prefer a half-turn staircase there. Turned or not – it should be uniform. Less because of the looks than because of the accident-free use even for the 1,001st time.

For example, we wanted such a staircase from the start and also planned it centrally in the house as a "eye-catcher." Around the staircase, the other rooms were then created (and that was quite a back and forth).

You can do that. But only either or: a staircase is either a secondary or a main element in the floor plan, but it must be clearly one or the other. Main or secondary element does not work. Very beautiful and interesting houses can be created by staging the staircase as a sculpture. My favorite pizza baker says: “A car starts at 150 hp.” This applies 1:1 to the minimum area per floor that a show staircase allows without compromises.

By the way, this staircase shape is more commonly found in practices, hotels, schools, or public buildings, as it – if properly constructed – requires a lot of space (because of the staircase void). There is then also a reasonable number of steps in the middle.

Wrapping around an elevator shaft has, in my opinion, quite its charm, and then the aspect of space consumption becomes relative.

Our staircase has a floor plan of 2.4mx2m. The width is 2.4m. So far, I had planned a running width of 1m, which would result in a stairwell width of 40cm. Would it be better to widen the running width to 1.1m and then have a stairwell with a width of 20cm? I think the stairwell is wasted space; a wider staircase could be more comfortable?
