Hello everyone!
I have a small question here at home. We have recently moved into a split-level house from -68 (unfortunately ytong). On the basement floor, I'm planning to build a dedicated home theater room, and the idea is to create a so-called room within a room.
There used to be a stove on the first floor, and the support for it is in the Hobby room, on the basement floor. (See attached image)
My question is, now that the stove is gone, is it safe to shorten these partition walls to the right in the image by about 300mm of the total 800mm they are currently.
There is no steel beam or similar supporting the floor, it's just lightweight concrete.
The floor itself is also lightweight concrete, and the first floor is made of lightweight concrete blocks. Flat roof.
I just want to get a little more out of the room, and if it's possible to remove a bit of these walls, I would be very happy.
I understand it's difficult to assess, but any tips and experiences are appreciated!

Doubtful, there is probably a beam on those wall pieces and as it seems, the floor structure (a joint) is probably on top of it, so removing a piece is probably risky for the load-bearing capacity of the floor structure, it could also be a light concrete beam with a lot of reinforcement in it.
That part of the calculation is not really my area, but there are others here who can, I see it somewhat as advanced to add an extra support there. Ultimately, it's the existing beam that supports the floor structure (the lightweight concrete blocks in the ceiling) and if any of the support is removed, it might not be good. Do you know how far into the wall section the beam sits, all the way out to the wall or out and rests on the wall? That's not something I can answer remotely.
Now I may be seeing/thinking completely wrong but shouldn't there be a joint on the lightweight concrete above that beam?
If that's the case, your reinforcement proposal will only support half.

Cannot verify what you are saying, but if there is a beam resting on those wall wings, it is not a good idea to cut away a part of it.
To place a new one next to it? Then perhaps the floor structure will come down.

There can't be any principal issues with replacing the lightweight concrete with steel. A 4 m long HEA 160 beam costs about 3000 kr. If you want HEA 160 profiles as columns, an additional 3000 kr will be required. The critical question is whether the slab can withstand the point loads that arise?
No. It's the columns that have to support the beam that constitutes the point loads. It's not certain that the basement slab can handle these. This needs to be checked.
Hello again, I have now been in contact with a drilling company and a structural engineer.
I received a price of 55,000 after ROT and find it difficult to assess if this is reasonable for the job as the quote does not specify material costs and hours.
Attached are drawings from the structural engineer.
What do you think?

Well, it is quite a significant job. Additionally, you risk the concrete "block" settling if they are not careful during the transition. Between the two wall sections that are close to each other and slightly to the left, there is a concrete casting (Picture #3). The question is how it interacts with the lightweight concrete beams next to it, i.e., further to the left in the picture.
You could entertain yourself by getting another quote.
I would probably leave the walls as they are and integrate them into the construction. Perhaps wall-mounted cabinets?
