Which staircase did you take?

That's rock solid. But they are connected to each other. You might see it a bit better here. Otherwise, each step is fixed to the wall with two bolts and the railing carries the rest of the weight in the middle.

Looks good, as if the steps are floating.

This is how ours is also fastened. I definitely did not want a cheek in front of the window.

But it only works with a narrow window, I think.

The stair vibrations are transmitted perfectly into the masonry there. That would NOT work at all for me.

No, the bolts are rubber-mounted in the wall. That means there is an additional sound insulation/vibration damping between the wall and the stairs.

And a general question: Why would that be so bad? Because of possible cracking or because of soundproofing?

Hello,

Knotted oak oiled ("wild oak") as bolt staircase with landing and bolts and railing made of stainless steel.
We really like it.

I still owed pictures:
Sorry, they are still rotated, the usual Windows-Exif problem. I don't have time to fix it right now.

Best regards,

Andreas
