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

And what is the pitch of the roof then? Where exactly is the 2 m (6.6 ft) line? You really have each piece of information taken away individually; ground floor and upper floor stairs form a single unit, especially with these floor areas.
If you’re building with Fullwood, you surely use one of their standard houses as a base – right? Then just name the model so it can be checked on their website. Links aren’t allowed here.

Regarding your drawing in post 62, a length of 15.5 m (50.8 ft) is given… usually one would assume an exterior measurement. But you then say the living area is 12 x 6 m (39.4 x 19.7 ft) interior dimensions... then the wall, then the practice with 3.5 m (11.5 ft) and another exterior wall. That would be close to 16.5 m (54.1 ft) exterior length somewhere.

Sorry… the roof angle is 45° pitch on a gable roof.
I can’t tell you where the 2 m (6.6 ft) line is exactly.

The 12 x 6 m (39.4 x 19.7 ft) interior dimensions are correct.

We never used a house as a template.
Fullwood always designs individually according to your wishes and budget.

I just measured our stairs. The tread depth is 26cm (10 inches) and the riser height is 19.5cm (7.7 inches). I wear size 44 shoes, and I find the stairs comfortable and safe. Our dogs don’t like the stairs, which isn’t necessarily a bad thing.

We’re trying to match those dimensions.
Do you happen to know the angle of your stairs?

No idea, since we have a quarter-turn staircase.

What angle do you find comfortable? At the moment, we are at 38-39°.

I don’t think my personal opinion on this would be very helpful. I should also mention that my decision-making and understanding are not really in the mathematical or technical area. However, I can say that compromising on the staircase is out of the question for me, as this element is too important and cannot be changed later.
I just measured our stairs and we have 27cm (11 inches) tread depth and 18cm (7 inches) riser height. Regardless of any building standard, I would consider this sufficient and comfortable FOR ME, although I thought my entire (floor plan 45) foot would fit; it actually falls short by about 2cm (1 inch).
Most likely, I would go up and down all public staircases many times to find what feels comfortable for me; numbers alone would not be enough help.

Joking aside... please keep comments like that to yourself in the future. They are only dismissive and not constructive in any way.

There was nothing dismissive. I described an impression and the question at the end—whether your very specific design is based on a correspondingly unusual set of experience and habits—is absolutely genuine.

I wouldn’t compare the stair pitch to the angle of a ladder; that’s misleading. 26cm (10 inches) corresponds roughly to the full foot length of a size 39 shoe; with larger feet, when going up, the heel may not be fully supported, and when going down, the toes may lose contact; this effect is more noticeable barefoot than with shoes. When the front edge of the step reaches the ankle when ascending, that’s probably about the limit of comfort and a secure walking feeling; for people with higher body weight, this limit might be reached even earlier.

The upper floor extends up to the kitchen. The living area is open to above (void). I hope that’s understandable.

That sounds like a design approach where “anything that doesn’t fit downstairs goes upstairs.” Besides, I would plan the staircase starting from the top floor exit; having detailed knowledge of the upper floor layout would be helpful for other contributors in the discussion.

I just measured our stairs and they have a 27/18 step design. Regardless of any standard like DIN, I would personally consider that sufficient and comfortable, although I thought that my whole (floor plan. 45) foot would fit; it’s about 2cm (1 inch) short.

I totally agree with you!
Now my small feet, size 42 shoes, are finally paying off 🙂

We are basically just wondering if the staircase might become too steep with age. According to DIN, anything between 29° and 45° (about 30° to 45°) is acceptable for a residential building.
