I have started taking down a wall between the hallway and the living room and discovered that it is framed like the other non-load-bearing interior walls in the house. See pictures, there are no standard measurements but approximately 30x30 studs both horizontally and vertically, then panels on both sides. Interior wall with wooden framing and peeling plaster, showing exposed studs and paneling between a hallway and living room under renovation. Close-up view of a non-load-bearing wooden interior wall with horizontal and vertical studs, showing the floor structure beneath, lacking basement support.

The wall also lacks support from the basement foundation below, so it seems that it is only standing on the floor joists. The wall between the kitchen and living room (green) is approximately 45x70 and stands on a masonry wall in the basement. The red wall (30x30 + panel) does not rest on anything in the basement foundation, not even the small yellow "projection" in the basement. Floor plan with highlighted non-load-bearing walls in red and green. Red wall lacks basement support, green wall partially supported. Question on load-bearing status. Floor plan highlighting a red non-load-bearing wall with paneling, a green wall supported by a basement wall, and a yellow protrusion, questioning load-bearing status.

Is this wall not load-bearing? Or is there something else that makes it load-bearing even though it is framed so weakly and especially appears to have no support from below?

When was the house built?
I suspect early 50s or earlier because it looks like a plank house. Those houses are not built in a standardized way like later houses. Load-bearing interior walls are determined by how the beams in the floor structure above lie, i.e., whether they rest on the wall or not.

Absolutely right, built in 1952!
Yes, the wall (both green and red in TS) is perpendicular to the joists. There are no other walls perpendicular to the joists, so the only alternative is if the structure is such that it is only supported by the outer walls.
But if the wall is load-bearing, I don't understand how the loads from that wall don't just go straight down into the subfloor and not down into the basement foundation🤔

The best thing is probably to bring in a structural engineer to look at the site and see how it looks and can be connected.

Or do you have any technical drawings or descriptions?

Unfortunately, no technical drawings or descriptions, I have a completed questionnaire from the building permit but it is illegible today.

I would have liked to hire a constructor but it's hard to find someone during the holiday season.

Nah, maybe it's best to wait

Have you checked if the municipality has anything?

Yes, I have requested everything but can't find anything helpful. I have C/C measurements of the floor structure, a little about wall constructions but nothing more than what I already know unfortunately. Very many fields are left unfilled.

Perhaps you can open up a little and check how the bjälklaget is constructed?
