Stair railing at 18 cm wall distance

Hello,

something definitely needs to be added here! Even in simpler steel and industrial construction, gaps between the staircase stringer and walls larger than 50mm are structurally closed to prevent twisting or buckling of the foot in case of stepping on them. In the worst case, a child under three years old can fit completely through a 18cm clearance!

How large is the clearance of the opening to the wall further up?
If, as in your example photo, the staircase connects at the top to a free, cantilevered ceiling, I would move the staircase 10cm further into the room and install the same railing on the window side as on the room side. Everything else looks awful!

Here is the floor plan of the positioned staircase and an example photo.

I've now read it 5 more times...and kept asking myself what, how, where... But now it's clear. The drawing is wrong. The staircase is drawn flush with the window/wall.

The staircase is shown flush with the window/wall there.

It probably will be, but there is the window reveal and the actual pane will be set back about 18 cm, thus also having this distance to the staircase.

We have just had to retrofit the windows along the staircase in a new building with a rod system similar to the one in the picture because the architect ignored the DIN standard for office buildings. It doesn’t look very appealing. But it was the same issue.

That will probably be the case, but there is the window reveal and the actual pane will then be recessed by about 18 cm and thus also have this distance to the stairs.

Ah, okay. So it's "only" about the "gap" at the window.

I have to (unfortunately) regularly walk up and down a staircase like this at one of our customers. Interestingly, it sways more from side to side than up and down. It is definitely an unpleasant feeling. But presumably, this is the inexpensive design for industrial buildings; in single-family homes, they might build more stable versions?
