Hi,
we are currently in the planning phase for our small wooden house.
Our architect wants to design our staircase according to standard 18065, but this does not match our size preferences.
We want a straight staircase with a length of 250cm (98 inches)... according to the standard, we would have to extend it to at least 290cm (114 inches). The width of 100cm (39 inches) remains unchanged.
Now to our question: Does a staircase in Lower Saxony have to be designed/built according to standard 18065?
In the technical building regulations, I found this paragraph.
Regarding DIN 18065
I could not find a clear answer as to whether I have to comply with the standard.

- 1. The introduction excludes the application to staircases in residential buildings of building classes 1 and 2 and in apartments.

We just want to save 30-40cm (12-16 inches) If it were that simple, many would do it. But most understand that a properly walkable staircase is important. A missing step depth of just 3cm (1 inch) is already a significant difference. Even if your staircase with 290cm (114 inches) complies with DIN 18065, I wouldn’t call it comfortably walkable yet. A typical straight staircase with a floor-to-floor height of 3m (10 feet) usually has a length of 350cm to 400cm (138 to 157 inches).

so you don’t have to redesign everything again. That’s why you first define the basic layout of the staircase and only then the rest. You can see for yourself that the staircase is a central element in the floor plan. You still have the chance to implement this properly. I would take it! But of course, I don’t have to live in that house.

NatureSys16 Nov 2024 16:25If you want to see and try out such a short staircase, it’s best to visit the Netherlands. Extremely short staircases are common in many houses there. I once visited a service provider where I never walked up the stairs without holding onto the handrail. Otherwise, you’re always afraid of falling.
So resale might be possible to Dutch buyers.
Is a staircase as steep as this one allowed as a primary emergency exit in Lower Saxony?

hanghaus202316 Nov 2024 16:45Why do you need to redesign? The architect said the design follows DIN standards.
Is the architect supposed to take over your DIY planning?

I would never design a single-family house with living spaces upstairs with a length under 3.70m (12 feet).

We just want to save 30–40cm (12–16 inches) so we don’t have to revise the entire plan. According to the stair calculator, a length of 260cm (102 inches) would comply with all limits... except for the tread depth, which would be 3cm (1.2 inches) too short.
We will take the advice (almost feeling like a reproach) and visit some stairs on site. 3cm (1.2 inches) too short makes a big difference for a staircase. We had a 250cm (98 inches) long stair in our 2.60m (8.5 feet) floor height, 100-year-old house with a 22cm (8.7 inches) tread depth. We all fell down that stair multiple times. It’s no joke. I would never do that in a new build, no matter what.
And yes, stair falls can be fatal. Not only as staged natural deaths in crime stories on grand stairs in mansions.

Timotheus17 Nov 2024 00:10Thank you for your assessments and opinions.
We plan to visit standard stair showrooms in the area to get a better sense of comfortable stair dimensions. (Not for space-saving stairs)
At the moment, we use a 140cm (55 inches) long space-saving staircase several times a day... maybe everything else just feels too grand for us.
Actually, I am a bit disappointed with our developer’s consultant. He never pointed out the staircase being too small... only the architect did.
Regarding the first emergency escape route... only the width and the handrail are specified.
I think it will end up being a quarter-turn staircase. It should not be too long.
But we will definitely get further advice on this as well.
