Building stair railing out of Ytong blocks - Does it hold?

Basically, you are right. But it is not that unlikely that over the years a "sufficient" impulse is transferred to the wall. Bumping into it with a heavy piece of furniture can be enough. In this respect, it seems sensible to me to at least drill a mounting profile or something else onto the stairs at the free end and buy it along. It "costs" nothing anyway.

Yes, it wouldn't hurt, that's true! One should be able to do it oneself as well..

Your stair railing is really great. We are also getting a double-L-shaped staircase with a relatively small stairwell, so the different riser heights are a challenge. Originally, we even wanted a wooden handrail, but then we would have to work with such offsets. At the moment, we are still in the planning phase, but I haven’t found a really good solution for it yet. In my 3D model, I assembled the railing from different blocks, which is why it looks so strange.

Could you maybe send me one or two more pictures of a railing? That would be really great.

Best regards, Jürgen

Works with drywall too. Profiles were screwed into the concrete staircase from the side. The drywall was then filled, sanded, and covered with fine plaster. And yes, it is brutally prone to dirt. That’s why oak will be placed on top in the next few days.

If the thread has been reopened here, then I'll write something here as well

We are also considering how to make the railing. At first, a glass panel was planned, but that's "somewhat" expensive... We want it to be as narrow as possible and a steel railing is also very expensive. With drywall construction, we fear it might not be stable enough. but apparently it works
how thin is the railing and the staircase itself?

We have exactly the same staircase, only our gap in the middle is "somewhat" smaller. About 1-2cm... I don’t know if you can attach the profiles there and therefore have to do masonry. The staircase is 110cm minus the railing, with plaster we then come down to only 100cm. Would like to be as wide as possible. What other alternatives are there?

The profiles are 3-4cm thick U profiles. However, it is not cheaper than a steel railing. After drywall construction, corner beads, filling, sanding, filling, sanding, and then the desired color/ textured paint follow. The railing is as stable as the substructure, with no savings made on profiles in our case... So it definitely works.
