Open up parts of load-bearing structure

[Jansson69]

Yes!

I see a hammarband and an overstycke in the material 45x70, does it match if you measure, and then skivtäckning, I don't see a balk, it's probably empty behind the wallboard?

It turned out to be a catastrophic picture, but if you look at the original

are you a designer by chance? 😅 we have all the blueprints from when the house was built.

Yes, I work as a structural engineer .
If you take a couple of pictures in the hole, it will be easier to determine if the wall is actually load-bearing or not. (assumed it was). If you have the construction drawings, it will be easier to determine if the wall is actually load-bearing.

Can't see a beam at all?

Neither can I. And if the wall is along the long side of the house, it's probably not load-bearing. Start removing all the plasterboard and then take a new picture.

 

[Suvi5700]

Isn't it what's behind the wood thing on the little opening we've made at the top? 😅🙈

No, doesn't look like it

But the "brown" part looks like there has been an opening right there before.

Then a load-bearing wall doesn't need to have a 'beam'.
I have built load-bearing walls with regular studs.
Admittedly, the wall had vertical studs at 45cc, noggings in between, and then the beam consisted of two studs with a 90-degree rotation between each other.

Also, just because the wall goes along the house doesn't mean it's load-bearing. Load-bearing also depends on the roof truss construction, span, load, and where on the width of the house the wall is. It might be another longitudinal wall that is load-bearing, or it could be spread across several walls.

A load-bearing wall doesn't necessarily need a 'beam'.
I've built load-bearing walls with regular studs.
Granted, the wall had vertical studs at 45cc, noggins in between, and then the wall plate consisted of two studs with a 90-degree rotation between each other.

Just because the wall runs along the house doesn't necessarily mean it's load-bearing. Load-bearing also depends on the roof truss construction, span, load, and where on the width of the house the wall is. Perhaps it's another longitudinal wall that's load-bearing or it's distributed across several walls.

Yes, I have spoken with the previous owner of the house and the brown part there (which is decorative vinyl 😅) is a previous opening, so just there, it isn't load-bearing. That's what I'm thinking.

 

[Suvi5700]

If the opening is to be made wider, a new stronger beam and new pillars are needed. To get the right dimensions for them, a structural engineer needs to do calculations based on snow zone, roof structure, roofing, weight from above, etc.

The fact that an opening is no longer needed elsewhere on the wall does not affect this.

Don't discourage Alexandra by exaggerating this.

 

[Suvi5700]

Yes, I have talked to the previous owners of the house and the brown part there (which is decorative plastic 😅) is a former opening, so right there it's not load-bearing. I think.

That's good.

 

[Alexandra Nilsson1]

According to old drawings, it is a load-bearing wall made with foundation wall leveling as the load-bearing wall

Non-load-bearing wall made with....
Was it empty

 

[Jansson69]

But that drawing shows the basement, is the wall you are going to tear down in the basement or the floor above?

Thanks, now I was closely examining the drawing and couldn't match it with how our entrance floor is built. It’s above the basement we are going to tear down 😅 However, unfortunately, I can't find such documents about the walls on the entrance floor

 

[Jansson69]

Thank you, I was looking closely at the drawing and couldn't figure out how our entrance floor is constructed. It's above the basement we are demolishing 😅 However, I can't find such documentation about the walls on the entrance floor unfortunately.

Remove the drawing from the post as it is irrelevant for your wall.
For wall no:2 is load-bearing for your floor, so I suspect that you have self-supporting roof trusses on the entrance floor, and then the wall you are demolishing is not load-bearing.

Wall no. 2, which one do you mean then?

Here are other drawings I found

We have opened up a bit more now.

We have opened up a bit more now. What I thought was a beam rests on studs, but I don't understand how it relates to the roof. On the other hand, my education is in social and not construction 😅 so what do I know…
