Is staircase DIN 18065 mandatory or not?

I absolutely cannot understand how you are trying to defend your staircase that is too steep.

We have a staircase to the attic that does not meet the standard. Previously, there was a space-saving staircase there that urgently needed to be replaced. The new staircase is a normal staircase but significantly steeper. Going up works well, but going down is a bit more difficult and definitely not for old age. However, this was consciously planned, as only storage space and the office are located upstairs. Otherwise, there would have been very little space left in the hallway. And we actually did not plan to spend our whole life in this house. So it works for us.

However, I would never consider installing such a staircase from the ground floor to the upper floor.

If you design the house in such a way that it is not possible to install a staircase that meets the standards with reasonable effort, that also reduces the value. Why do that in a new build?

How many times do I actually have to write that the staircase meets the standard??? DIN 18065 is complied with 100%. I have already mentioned that the standard must be met even if the building authority doesn’t care.

I keep having to read these accusations, which annoys me greatly. We welcome constructive suggestions! Proposals are not useful right now as we do not yet have the finished floor plan.

Our house measures 6.5m x 12.5m externally... so relatively narrow. For this reason, after consultation, we decided on a 1/4 turn staircase. To avoid being too close to the wall, the turned part must rather be kept short. The stair builders and we came to about 3m and 1.3m (straight part 3m / 1.3m turned). Thus, we meet the standard and have a space-saving staircase. Furthermore, we have tested various staircases and can come to terms with the minimum tread depth. We don’t want children and only the bedroom is planned on the upper floor.

I am attaching a sketch from us.

The wall between the kitchen and staircase will be extended to 3m. Please ignore the practice as it does not belong to the main house. Internal dimensions are 12x6m.

Before anyone asks: We have working dogs that require a fixed place.

There is simply missing information about the upper floor width .. OG=full floor or attic with which knee wall height?

Because space-saving and more room-friendly, stairs can usually be planned along exterior walls with the house width.

And yes, your last stair measurement complied with the standard value, but the 23.2 cm tread depth is really not very practical. As already described here, especially when going down. Measure your foot length.

Years ago, I made 2 plans for a narrower house. The examples are only meant as inspiration. In these, there is only a small area on the ground floor for the arrival of external connections, the actual technology is then located on the upper floor. The room program does not quite correspond to yours either, but it is only meant to provide ideas. Here, 2 full floors were also considered. The interior width is even only 5 m. It was for a family with 3 children.

Option 1 could also work with knee wall



Option 2 requires a full upper floor

Our open staircase to the [DG] has a tread width of 230 - 260mm (depending on the step). I would never, ever have this tread width installed for the staircase from the [EG] to the [OG]. Two years ago, I had to wear a foot brace for a few weeks. Going up was fine, going down I really had to be careful. But well, you have probably been told this often enough, obviously also by the architect and staircase builder. In the end, you will have to live with it.

How often do I actually have to write that the staircase meets the standard??? DIN 18065 is 100% complied with.
I keep having to read these accusations, which annoys me a lot.

Understandably, the repeated mentions annoy you, but people also react to the fact that you defend this staircase part almost with various arguments, which in turn leads to criticism. Be happy, people are actively engaged with your topic!
On the other hand, it can also show you how fundamentally important this component is and how immensely disadvantageous it can be to overlook something or perhaps not evaluate things thoroughly enough.
I once worked on a new public building. From the huge entrance area, a 4m wide staircase led to the first floor (DIN for public buildings certainly observed). Many employees did not use this staircase because it was simply too steep and the tread was too short; there was an elevator anyway.
In short: The DIN standard is important and regulates fundamental aspects, but there is also the very personal DIN-DNA that can make my life permanently more comfortable (this is why you build a house). So it does not give you the assurance that your life will then be comfortable enough. In this respect, the DIN must be observed, but it can be sensibly exceeded significantly to achieve the desired result for you.

We appreciate constructive suggestions!
Suggestions don’t make sense right now because we don’t have the final floor plan yet.

Exactly – I believe it will be exciting – in a positive sense!

I’m adding a sketch from us. [Bild] The wall between the kitchen and the stairs will be extended to 3m. Please ignore the practice as it does not belong to the main house. Interior dimensions are 12x6m. Before anyone asks: we have service dogs that needed a fixed place.

That looks like a 40-foot container scaled up 2.5:1 in height or resembles a showman’s living wagon with a pull-out bay window. Were you workation globetrotters?
