Hello builders!

I want to create a new opening from the kitchen into the room, but I'm not sure if it's a load-bearing wall or not. The wall is made of wood, covered with plasterboard. The length of the new opening will be about 2 meters. The house is 1 story. I contacted the municipality, and they provided a plan, but unfortunately, it's not marked.

Do I need a permit for this work, can I install the beam myself if the wall is load-bearing?
 
Publish the drawing you have and mark where you want to make an opening.
 
Yes, I will publish now, but it is not ready

The wall in which you want to create an opening is load-bearing. You must install a beam. The size of that beam primarily depends on the snow load that must be accounted for. The size of the snow load depends on where in Sweden you live.
 
Do I need to get permission from the municipality or can I calculate and install it myself?
 
You need to submit a building notification to the Building Committee. You can do the installation yourself, but I don't think you can calculate the beam yourself.

In principle, you are probably right, Justus.
But if TS leaves a post, as indicated on the drawing, it might still work.
The distance between the red lines on the drawing looks to be about 1.2 m, which is equal to the truss spacing:

If that's correct, it can naturally work, but you need to be a bit handy and understand how the house is built and be able to measure accordingly.
