Is staircase DIN 18065 mandatory or not?

And what is the pitch of the roof then? So where would the 2 m line be. You really let every piece of information be taken from you individually, staircase ground floor and upper floor are basically one unit, especially with these surface dimensions. If you are building with Fullwood, then you surely take one of the standard houses as a basis - right? Then just name the model, so one can take a look at it on the website. Link is not allowed here. Regarding your drawing in , there is a length of 15.5 m specified... one would normally think of exterior dimension. But you then write that the living area has 12x6 m interior dimension... then wall then practice with 3.5 m and outer wall again. That would then be somewhere close to 16.5 m exterior dimension.

Sorry... the roof angle is 45° gable roof. I can't tell you where the 2 m line is located. The 12x6 m interior dimensions are correct. We never took a house as a template. Fullwood always designs individually according to your wishes and budget.

I just measured what our staircase has. 26 cm tread and 19.5 cm rise. I wear size 44 shoes and find the staircase comfortable and safe. Our dogs don't like the staircase. Which is not so bad. [/QUOTEN

We are trying to enable those dimensions. Do you happen to know the angle of your staircase?

No idea, since we have a quarter turn.

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

I don't think my individual statement would help you. I also have to say that my decision-making options and abilities are rather not in the computational/technical field. But I can tell you that a compromise on the topic of stairs would not be an option for me, as this component would be too important to me and also unchangeable later. I just measured ours and we have 27/18 steps. Regardless of any DIN, I would consider that ENOUGH or comfortable FOR ME, although I thought my entire (floor plan. 45) foot would fit on it; it is missing about 2 cm. I would probably walk up and down all publicly accessible stairs dozens of times to secure the measurement that is comfortable for me; numbers alone would not help me there.

Jokes aside... keep such comments to yourself in the future. They are only disparaging and in no way constructive.

There was nothing disparaging. I described an impression and the question at the end, whether your very special planning is explained by a correspondingly unusual wealth of experience and habits, is absolutely serious.

Don't you think 26cm tread width is enough? [ / ] What angle do you find comfortable? At the moment we are at 38-39°.

I would not compare a stair rise to a ladder leaning angle, that's misleading. 26cm is a full support of the foot length in shoe size 39; with larger feet, when going up the heel is partly unsupported, and when going down the toes; barefoot both come into play more than when shod. When going up the step edge is in front of the ankle, this is roughly the limit of comfort or a safe feeling while walking, possibly earlier with "overweight."

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

That sounds like a "only what no longer fit below comes up" planning doctrine. Incidentally, I would plan a staircase from the exit point; knowledge of the upper floor would be useful to the other discussants for that.

I don't think my personal opinion on this would help you. I also have to say that my decision-making options and abilities are rather not in the computational/technical area. But I can tell you that a compromise on the topic of stairs would not be an option for me, as this component is too important to me and later also unchangeable. I just measured ours and we have 27/18 steps. Regardless of any DIN standard, I would consider that SUFFICIENT or comfortable FOR ME, although I thought my entire (floor plan. 45) foot would fit on it; about 2 cm are missing. I would probably walk up and down all publicly accessible stairs dozens of times to secure the measure that is comfortable for me; numbers alone would not help me there.

I see it exactly the same way as you! Now my small feet with shoe size 42 finally pay off :) Actually, we are only wondering if the stairs could be too steep in old age. According to DIN, anything between 29-45° is OK for an apartment.
