ᐅ Is a staircase required to comply with DIN 18065 or not?

A stairway is not like a wall that can be changed if needed, nor a door that can be made wider if necessary. I would never expect a compromise or an “it will work more or less” attitude for such an important part of a house. I even believe that if a house or floor plan does not accommodate a properly sized staircase, it must be redesigned until it does. And not everything that just somehow fits or goes unnoticed should actually be implemented.

I recall a post that was planned right in the middle of an access way, and the planner initially told us that it was easy to walk around it. Looking back now (without this post)

We just want to save 30-40cm (12-16 inches) so we don’t have to redesign everything again.

No matter how long it takes, I would not want to live with this perceived flaw for potentially my entire life.

@Timotheus My request would not just be to stop sharing the house project, but to genuinely address all the points raised here. I have read some interesting comments that each deserve a clear response.

I believe my last post was unclear.

We will plan and install a quarter-turn staircase according to DIN standards.
The incline angle will be around 38 degrees. This is still within the allowed range but somewhat steeper than very comfortable staircases.
Yesterday, we tested several staircases and are very satisfied with this choice.

I take all your concerns and advice to heart!

May I ask how old you are? Until my late 30s, I also thought stairs only become a problem after age 70. I’m now in my mid-forties and notice that stairs are less enjoyable. My wife has felt this for longer due to torn cruciate ligaments.
This is partly because the eyes develop quirks after 25 years of screen exposure, causing depth perception—especially under non-laboratory lighting—to worsen. On the other hand, muscles, despite or because of training and slower recovery, don’t perform like they used to. After an 80 km (50 miles) bike ride, I walk the next day as if I’d just finished a mountain stage of the Tour de France. The last thing I would build into my home is a “it’ll probably be okay” staircase—neither for design nor cost reasons. The DIN standard actually makes sense since it’s based on experience and ergonomics.

We are both in our early 30s.
I can definitely understand your point.
Our neighbors (who also have an old vacation home with a space-saving staircase) have moved a bed into the ground floor (living room) so they don’t have to climb stairs anymore when they have joint pain or other issues.

Since we want to meet the DIN standard, that should be fine, right?

A staircase is not like a wall that can be altered if needed, or a door where you can simply increase the width if required.
I would never accept compromises or a “it’ll probably work out fine overall” attitude for such an important part of a house.
I even go so far as to say that if a house or floor plan doesn’t accommodate a "proper" staircase size, the plan must be revised until it fits. And: not everything that barely fits or isn’t explicitly objected to should really be implemented.
I recall a support post planned right in the middle of the access, and the planner initially said you could easily walk around it. From today’s perspective (without that post)

No matter how long it takes, I wouldn’t want to live with a flaw like that, even possibly for my entire life.
@Timotheus My request is not only to upload the house project, but also to directly address all the points mentioned here. I have read some interesting comments that deserve a specific response.

We have long abandoned the initial desire for a space-saving staircase.
The staircase will be longer but can remain at the planned location thanks to the winding section.

Which interesting comments did I not respond to?

This was not meant as a criticism.
I had read through the entire thread and remembered some comments that I didn’t see a direct reply to afterward. Since you switched to a different staircase design, that might have resolved itself by now, but that was the impression I got while reading.
If it was only me who noticed this, then I must have been mistaken.

People often assume that difficulties with stairs mainly occur when going up. However, when stair use becomes painful due to injury—even at a younger age—it usually affects going down stairs.

... it seems a part of this latter sentence is missing here.
