Are the walls load-bearing?

[mkrntz]

Hello,
I just bought a Hultsfred house from 1959. I've understood that it's a fairly common model. 87 sqm area, equally large basement. Unfinished attic.
I would like to do some remodeling and can't quite figure out which walls are load-bearing. All interior walls seem to be built in the same way, 3"-fiber planks with wood fiber boards on both sides, center-to-center 300.

In the attached images, you can see both the basement and "ground floor" as well as what the walls look like. I am quite sure that the wall with the green arrow is load-bearing. But are the walls with the red and blue arrows also load-bearing? What do you think? How can I best find this out?

Thanks in advance!

What do the roof trusses look like in the attic?
Do you have a sectional drawing too?

This is the only sectional drawing I have. I haven't been up in the attic more than during the inspection, so I can't say much more right now as I'm not in the house at the moment.

Risk that the walls drawn on the section drawing are load-bearing, i.e., exterior walls and interior walls roughly under the roof ridge, meaning walls with green and red arrows.

To be completely sure, you should probably hire a structural engineer to check on-site. Such a professional can also size beams and columns for a construction notice if you decide to remove a load-bearing wall.

Arrow more red and green are likely load-bearing, they are directly across the roof trusses. but not blue, if they are to be removed, a beam will probably be needed as a load-bearing element at the roof.

The wall at the blue arrow is not load-bearing.
However, walls at green and red are load-bearing, with the greatest certainty. The same applies to the wall between the kitchen and living room/hallway.
