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.

Regarding DIN 18065
- 1. The introduction excludes the application to staircases in residential buildings of building classes 1 and 2 and in apartments.
I could not find a clear answer as to whether I have to comply with the standard.
Addendum: The exact same wording is stated in the Lower Saxony State Building Code.
Then you can probably do it. For me, it would be an absolute no-go and would also reduce the house’s value for a potential resale. But hey – it’s your money and your house.

Our house is 6.7m (22 feet) tall and therefore falls under building class 1.

I assume the building authority does not check whether DIN 18065 is complied with. Their focus is more on the legal aspects.
As long as you use it only privately, it is unlikely to bother anyone. However, if a child were to fall, the situation would look very different. The architect pointed out the standard to you, so they would be exempt from liability.
Every space-saving staircase is steeper and still functional. It is not comfortable, though. We share the same assumption.
I think we will need to discuss this again with the architect.
Possibly, a quarter-turn staircase could be a reasonable alternative.

We are well aware that the staircase is steep.
At the moment, we are renting an old holiday home (gable roof) with a really small space-saving staircase. “At the moment” is a good point. You might be fit right now. Just spend two weeks sick in bed, and your thigh muscles will need retraining. That doesn’t happen overnight.
If you have to go down this staircase every day, over time it will also strain your knees.

Every space-saving staircase is steeper and it works too. It also depends on which rooms the staircase connects. If it is only the bedroom, you might only need to use it once a day.
If you want to really live and use the space constantly, carrying cleaning supplies, laundry, or other everyday items, I would definitely advise against it.

You know its shortcomings and want it again, even buying a plot of land just to economically undermine it with a hard-to-sell house? – Well, I suppose that is one of the "blessings" of a free country, that applying common sense is not mandatory.
The unreasonable staircase is "set," and the opportunity to discuss the design is not to be taken?

The unreasonable staircase is "set," and the chance to discuss the design is not wanted? We just want to save 30–40cm (12–16 inches) so we don’t have to redesign everything again.
According to the staircase calculator, with a length of 260cm (102 inches) we would meet all limits... except for the tread depth. That would be 3cm (1 inch) too short.
We will take the advice (almost an accusation) seriously and visit some staircases on site.

This would be 3cm (1.2 inches) too short. “To fit except that it would be tight” is a contradiction. Even ballet dancers don’t walk on their toes all the time. Going down stairs backwards might be amusing as a gag sometimes, but it wears out quickly. I’m in my mid-fifties, but I wouldn’t wish a minimally standard staircase on my worst enemies... in the worst case, I’d find myself in quite a difficult situation.
