Hole making in load-bearing brick wall - measures? (Structural drawings attached)

[WestbergA]

We are planning to renovate a bedroom and move the bedroom door. The wall it will be moved to is a load-bearing brick wall.

I am trying to form an idea of how major/minor this project is and would appreciate a sketch of actions that may need to be taken.

I am attaching the construction drawings and have placed a pen on the images to indicate where I want to move the bedroom door in the future.

Quick summary:
- Floor slab: "Cast-in-place concrete floor slab H = 160 mm, Concrete II Std K250T, Reinforcement ks 40, concrete cover = in beams 30 mm, otherwise 15 mm"
- Load-bearing brick wall: "At living room 1/2-stage (120 mm) brick. Otherwise, studs 45x145 c 300 with double posts according to plan."

There is already a door at the "Guest room" through the load-bearing brick wall. However, I can't find any information about an extra load-bearing stud or similar above the door frame on the drawings.

Thanks in advance!

Isn't it usually the case that brick cannot span across openings, so you need to install a reinforced concrete beam or steel beam before creating the door opening?

The latter always seems to be the engineer's solution when they need to create openings in brick walls in the BRF's old buildings.

I am trying to get an idea of how large/small this intervention is and would appreciate a sketch of actions that may need to be carried out.

One action is usually to submit a building notification to the municipality, and in order to show how it has been determined how the load-bearing structure should be done, one might need an opinion from a structural engineer.
