Help on: Load-bearing wall? 70s house, open up kitchen/living room

[Bagaregårdens BK]

Hello!

I'm planning to open up between the kitchen and living room in a single-story house from '74 (flat roof, no upper floor). I've attached a drawing:

What do you think: is the wall load-bearing?
It's quite central in the house.

I understand a structural engineer is needed before demolition, but I'd love to hear your experiences.
If it is load-bearing, are you thinking of using an I-beam for reinforcement?

Attached are the drawing and the attic above.

Thanks! 🙏

These are not trussed rafters so the wall may very well be load-bearing.

How thick is the wall compared to the other walls? Is it thicker than those running perpendicular to the one you want to demolish? Two of the bedrooms have interior walls along the "same line," are they as thick as the one between the living room and the kitchen? I would spontaneously say that those walls are a heart wall and thus load-bearing.

The picture from the attic, can you lift the insulation a bit and see if there is another parallel stud with the one the sheathing is screwed into? Maybe you can also see if it rests on the wall then.

Do you have access to the section drawing? (Where you can see the house in cross section)

That's where load-bearing walls are usually clearly visible.

Load-bearing walls are usually clearly visible there.

Can this help?
