Can these protruding pillars be demolished?

Looks like gypsum, so just open it up and take a look

I think it looks like bricks in there, possibly aerated concrete blocks.

edit:
hehe, you got ahead of me.

Exactly, wrote that in the post after, yes, it's stone. But as mentioned, if you want to know, you have to open up a reasonable hole that can be filled and then plastered or drywalled or whatever he plans to do once he's removed the stones.

The right one feels slightly more hollow when tapped than the other. Chipped off a piece of the stone on the left one as per the picture.

The decorative stone will be removed regardless.
The neighbor still does not respond to knocking.

If it looks like that, it's likely to be load-bearing in some way for some reason.
It was itching in the fingers and the decorative stone was unwanted, was it?

 

[noupe]

A reasonable hole does not affect any bearing capacity, alternatively you can drill in and insert a cheap optical camera (available for a few hundred kronor that is sufficient for the purpose).

Yes, the decorative stone must go. I planned to build a custom shelf between the protrusions but was surprised to find that they weren't on the original blueprint.

What should I look for?

What should I look for?

To see if there are any installations (ventilation, plumbing or other). If it's empty, then the only question is if it would be a load-bearing remainder for some unknown reason. If no one here on the forum can dismiss it, then it's probably best to bring in an engineer for an hour who should be able to easily determine that.

Doesn't it look like there is plaster with white paint and then tiles on it? In that case, the pillars can't be newly built, can they? Or am I seeing it wrong?

The question is really just if they can be removed.

To see if there are any installations (ventilation, plumbing, or other). If it's empty, the only question is if it might be a structural remainder for some unknown reason. If no one here on the forum can dismiss it, then bringing in a structural engineer for an hour would easily determine it.

Shouldn't this be visible in the drawing?

 

[Fotografen]

What indicates that the drawing is correct and up-to-date? It might have been changed afterward, or it wasn't made according to the drawing...

That's true. I'll check with the neighbor tomorrow and otherwise peek inside. I'll get back with the results.
