Podest stair combination: platform stair and half-turn stair

Isn't your planner somewhat better than your DIY?

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

I am always open to alternative solutions. However, this one does not appeal to me. I imagine the steps where a landing could be to be so "unrhythmic" in practice that I see it as a health hazard.

What step depths and stair heights do you assume? (Single-family house, 2.5m room height) It is more of a calculation example, although unfortunately I do not know how to calculate it.

You do not have to reach the ceiling height, but rather the floor height of the upper floor. Therefore, you need the distance from the floor of one level to the floor of the other level. The DIN 18065 describes staircase dimensions. For step height, between 17 and 19 cm is common. For tread depth, between 26 and 30 cm is usual. The incline is ideally between 30 and 35 degrees. The walk ratio is also important; 63 cm is recommended here - it is calculated by step height x 2 + tread length. Now you have everything to calculate.

I will quote . "You can see in the ........example that the 'landing' was converted into an evenly divided four-part turn. This is botched for several reasons: secondly, it would be better to use five steps for this. Three would also be an odd number, but five work better so that the step depth (measured along the walking line) harmonizes more evenly with the stride length of the straight steps 'before' and 'after' the turn. And first of all, the wrong points lie at the transition between the straight and turned sections here: at half past one / twelve / half past eleven o'clock are the pitfalls / in the direction of the incline downward, the front edges of the turned steps are at the tip of the foot. Better would be in these positions the middle (i.e. under the middle of the foot) step depths. The step edges therefore should be shifted 'downward' by half to a whole step depth. The last straight step before the turn, seen from above, should also be included in the turn just as the first step that turns back into the straight section should be. So your tool is only good for showing a trainee stair builder in their first year what would get them a grade six. This simulation could also be excellently used for an accident insurance training film."

May one assume that you are trying to manage with the 2.8 m including landing from your DIY plan? I did the math. With a story height of 2.88 m, you can manage with 18/27. Even with a landing. The stair then fits your 2.8 m.

I did some calculations. With a story height of 2.88, you get 18/27. Even with a landing. The staircase then fits your 2.8 m.

"You can see in the ........example that the "landing" has been converted into an evenly divided four-part winding. This is botched for several reasons: secondly, it would be better to use five steps for that. Three would also be an odd number, but five work better so that the step depth (measured along the walking line) harmonizes more evenly with the stride length of the straight steps "before" and "after". And first, the wrong points lie at the transition between the straight and winding sections here: at half past one / twelve / half past ten o’clock are the danger spots / in direction of the slope downward, the front edges of the winding steps are at the toes. Better would be in these positions the middle (i.e. located under the middle of the foot) step depths. So the step edges should be shifted "downward" by half to a whole step depth. The last straight step viewed from above before the winding should also still be included in the winding, just as the first step viewed from above, bending back into the straight section, should be included. So your tool is only good to show the trainee stair builder in his first year what a failing grade looks like. This simulation could also be perfectly used for an accident insurance training film."

Is it allowed to assume that you are trying to make it with the 2.8 m including landing from your DIY plan?
I did the math. With a floor height of 2.88 you get by with 18/27. Even with a landing. The staircase then fits to your 2.8 m.

Thanks. I took away that an additional stair step in the winding part would be better. The consideration is correct, I was speculating on the 2.8 m. I liked the idea of using straight steps instead of winding steps and gaining extra height over the part that is usually a landing. I’m not really a fan of a half-winder staircase, so I had other considerations. Unfortunately, the landing staircase takes up too much space, but then it will probably be a half-winder staircase if nothing else works. Thanks to you all.

You have 2.8m of space. In my opinion, a platform staircase would also fit there.
