Hello to you home builders, I know this is a forum for house building and I myself have a condominium apartment, but I thought I'd still try to get an answer to a question if that's alright.
I would like to cut an opening in a concrete wall between two rooms in my apartment, but I have no idea what it might cost for something like this, I probably can't manage it myself? Or if you're allowed to do something like this (a building permit might be required) the opening should be about 1m.
Very grateful for any answers. Thanks,

We have opened up between two rooms in the basement (live in a house). Didn't think about building permission... But I don't think it's needed :-/. But I don't know what's required for a condominium. Our neighbor has such a company so he did it for us as he also dug up the floor and some other bits and pieces. Therefore, I don't know the price for just that opening since we did so many different things at the same time. But you can probably do it yourself. It's heavy but it went quickly. Not much help, unfortunately...
If it's a concrete wall, it's likely load-bearing. This means you at least have to file a building application. And of course, obtain the board's approval (if you don't inform the board and something were to go wrong, it could be grounds for "forfeiture" of the housing rights). You should have the board's approval even if it turns out the wall is not load-bearing.
I would definitely consult a structural engineer if I were to make such a hole in a possibly load-bearing wall (and if I were on the board of your association, I would not approve it without an engineer's report). It's likely not a problem, and a structural engineer should be able to determine this with about an hour's consultation. Another consideration is whether there is a risk of electrical or water lines embedded in the wall.
Regarding the actual work, one might consider whether the hole could be made with a larger model angle grinder with a diamond blade (such tools are no longer expensive). Of course, it depends on how thick the wall is. And I think they might be available for rent as well. Just keep in mind that if you cut out the entire piece in one go, it will be a "heck" of a thud when it lands, as you might have trouble lifting it.
