Open up the room - tear down interior wall

[pacman42]

I agree with your conclusions but the above I do not understand, it is rather an indication that it could be load-bearing.

Not in connection with the other. But normally yes. Here there was no such wall in that direction otherwise. Sorry I wasn't clear about this.

To be precise, it also depends on the floor and the construction of the house overall. For example, I have no load-bearing walls on the upper floor, but three transverse load-bearing walls on the ground floor, they have laid the intermediate floor in the longitudinal direction of the house.

The entire lower floor is load-bearing throughout the house with either beams or load-bearing walls.

The upper floor (1.5 stories) has a large open living room in the middle and 2 rooms on each side. One room is smaller and has an inner wall. "Behind" it there is a closet and a small bathroom.

There are attic spaces on both sides, about 1-1.5m wide.

The entire beam in the ceiling is not being removed, only where we want to open up. In other words, the red line.
The beam against the outer wall (blue) we want to remove, and the one on the right marked in green will be moved where the wall ends.

I understand it might not be "easy" to answer whether it's possible or not.
But I think the load-bearing should be in the roof trusses and the "floor." I don't know all the fancy terms so I apologize in advance 🙈

That's true, but one should be aware that the roof trusses' support legs extend down into the knee wall.

In addition to load-bearing walls, there are stabilizing walls that, for example, prevent the house from tilting or twisting when it's very windy. This is what pacman42 mentions a bit in post 14. The knee walls can have such a function besides "concealing" the support legs.

Okay, why do you think it shouldn't be touched? Do you think it is load-bearing?

It completely depends on how it looks above the ceiling. If it's only a thinner beam attached to the ceiling, you can just remove it. If it's part of a beam that goes through the ceiling and the top of the attic, I wouldn't remove it.

Can you check how the top of the beam ends, is it flush against the underside of the ceiling?
