ᐅ Is a staircase layout with two quarter turns plus a landing possible within a maximum area of 2.4 by 2.4 meters?

The hallway is interrupted by a landing, and the walking rhythm is uneven.
In your case, this happens twice. Additionally, you have a different number of steps in each flight. Landings and irregularities increase the risk of accidents. So for you, it’s doubly problematic.

I would advise against a staircase with landings or... suggest changing the floor plan to accommodate a different type of staircase. But then you basically start almost from scratch, as I assume your stairwell opening is fixed and cannot simply be widened.

By half-turn, do you actually mean a staircase with two quarter turns?

It’s called a three-flight U-shaped staircase and has two turns, or a 2/4 turn, or as Robin says, 2 x 1/4 turns. I looked it up.

This staircase design is usually found more often in medical offices, hotels, schools, or public buildings because—when built properly—it occupies a lot of space (due to the stairwell). There is a reasonable number of steps in the middle flights there.

In single-family houses, I assume it’s avoided because having two steps, then 3 or 5 steps, can be dangerous in everyday use.

Google returns numerous different terms here.

I meant a half-turn staircase, at least that’s what I get when I search for "half-turn" on Google.

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

From what I understand, you would still prefer a 2 x 1/4 turn staircase with 16 steps, 18.44 cm (7.3 inches) rise / 26 cm (10.2 inches) tread, and design it with a 1 m (3.3 feet) rough opening width?!

I have a rather unique perspective on staircases; to me, they are simply a means of moving up and down. Personally, I would pay more attention to the materials used.

I don’t like the two landings. Regular landing stairs, to me, are more reminiscent of apartment buildings, but that could also be a matter of personal taste.

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

16 risers 18.44cm/25.94cm (7.26 inches/10.21 inches)
Tread depth: 62.82cm (24.74 inches)
Rough opening width: 100cm (39.37 inches)
Floor plan: 240cm x 200cm (94.49 inches x 78.74 inches)

Is there any objection to this staircase?

And why exactly do I walk there with a limp?

That has already been well explained.

The staircase doesn’t necessarily have to be bumpy; basically, any staircase that disrupts the step rhythm is a bit bumpy (ours too). I once read something that it’s generally best to climb stairs without interruptions, like landings, and that this tends to result in fewer accidents.

No one in your family will have exactly a 63cm (25 inches) step length, or only by chance. People subconsciously adjust to the difference from the “standard” when using the first steps. If the step length changes afterwards—for example because the landing length isn’t an exact multiple of the step length—then climbing the stairs requires attention (again subconsciously, but still using cognitive resources), which increases the risk of falling.

Unfortunately, your posts don’t contribute to finding a solution.

I keep my expectations low and am also happy with contributions that help avoid mistakes.

Can you make a proposal, or is your opinion that the staircase must be a half-turn staircase? What would be reasonable dimensions for a staircase with straight steps?

I don’t know your floor plan, so I can’t say for sure whether I would prefer a half-turn staircase. Turned or not—the steps should be consistent. Not so much for aesthetics, but to ensure the staircase can be used safely even the thousand-and-first time.

For example, we always wanted a staircase like that and placed it centrally in the house as a 'showpiece.' The other rooms were then designed around the staircase (which required some back and forth).

That’s possible. But it’s always either/or: a staircase is either a secondary element or a main feature in the floor plan, but it must be clearly one or the other. It cannot be both main and minor feature simultaneously. Very attractive and interesting houses can result when the staircase is staged as a sculptural element. My favorite pizza maker says: “A car starts at 150 horsepower.” The same applies 1:1 for the minimum floor area per storey that a show staircase requires without compromise.

By the way, this staircase design is more common in practices, hotels, schools, or public buildings, since—if properly built—it takes up a lot of space (due to the stairwell). There is usually a reasonable number of steps in the center.

Surrounding an elevator shaft, in my opinion, this can be quite appealing, and then the issue of space consumption becomes less significant.

Our staircase has a floor plan of 2.4m (7 feet 10 inches) by 2m (6 feet 7 inches). The width is 2.4m (7 feet 10 inches). So far, I had planned for a tread width of 1m (3 feet 3 inches), which would result in a stairwell opening of 40cm (16 inches) in width.
Would it be better to increase the tread width to 1.1m (3 feet 7 inches) and have a stairwell opening of 20cm (8 inches)? I think the stairwell opening is wasted space, and a wider staircase might be more comfortable.
