Is staircase DIN 18065 mandatory or not?

We just want to save 30-40cm

If it were that easy, many would do it. Most just realize that a reasonably walkable staircase is important to them. A missing tread depth of 3cm is already the corner of a house. Even if your staircase with 290cm complies with DIN 18065, I would not yet speak of a comfortably walkable staircase. The typical straight staircase for a floor height of 3m will usually have a length of 350cm to 400cm.

so as not to have to redesign everything again.

That’s why you first define the basic outlines of the staircase and only then the rest. You can see yourself that the staircase is a central point in the floor plan design. Now you still have the chance to implement the matter properly. I would take advantage of it! But I don’t have to live in the house.

If you want to look at and test such a short staircase, it is best to go to Holland. Extremely short staircases are common in many houses there. I was once at a service provider, and I never walked the stairs without holding on to the handrail. Otherwise, you were always afraid of falling.

So resale maybe possible to the Dutch.

Is such a steep staircase in Lower Saxony allowed as the primary escape route?

Why do you have to reschedule? The architect said he plans according to DIN. Should the architect take over your DIY planning?

?? I would never plan a single-family house with living rooms upstairs with a length under 3.70.

We just want to save 30-40cm so we don’t have to redo everything again. According to the stair calculator, a length of 260cm would comply with all limits... except for the tread depth. This would be 3cm too short. We will take the advice (almost an accusation) to heart and look at some stairs on site.

3 cm too short is a world when it comes to stairs. We had such a 250 cm long staircase with a floor height of 2.60m and a tread depth of 22 cm in our 100-year-old house. We all fell down this staircase multiple times. That’s not funny. I would never do that for anything in a new build. And yes, stair falls can also be fatal. Not just as staged natural deaths in crime novels on open stairs in villas.

Thank you for your assessments and opinions. We will visit regular stair studios in the area to get a feel for comfortable stair dimensions. (Not for space-saving stairs) At the moment, we use a 140 cm long space-saving staircase several times a day... maybe everything else already seems too pompous to us. Actually, I am a bit disappointed with our developer’s consultant. He never pointed out the staircase was too small... only the architect did. Regarding the first escape route... only the width and the railing are specified. I think in the end it will be a quarter-turn staircase. It should not be too long. But we better get advice on that again.
