Covering for indoor concrete stairs -> wood, vinyl, natural stone?

If the substructure is executed as a precast concrete staircase, then the wooden covering, which here looks like a folded structure, should "simply" be just a covering without a load-bearing function and thus should only account for the price of a covering. Or? I would be interested..... including the railing. Would like more info about it.

Sorry, I can't help with that. I've only seen it as a sample.

I didn't know that they are also called folding staircases when they have a substructure. Learned something new

You are already correct, it is not a folding staircase if there is a concrete substructure - but it was probably the best term to clarify what was desired.

Accordingly, it is "only" a wooden covering, which is not comparable to the costs of a folded plate staircase at all. The photos shown by , especially the railing that seems to rest on the staircase, do not comply with DIN requirements and cannot really be built this way.

does not meet the DIN requirements and therefore cannot really be built like this.

I wouldn't be so sure about that. The look is actually unique now - many staircase builders do that (also as a normal folded plate staircase).

I have no idea about the details of the DIN, but when it comes to railings, you have to be careful. In a single-family house, a lot is allowed. And do not be fooled by the costs. If you use solid risers and treads, it is probably still cheaper than if it were a proper load-bearing folded structure staircase. However, I believe I have seen prices between 3-5k for one floor here in the forum. Of course, you can also have it made from parquet; there are also special parquet stair edges.
