Is this wall load-bearing? 70s townhouse

[TW67]

Hello

I live in a terraced house from the 70s. It has two floors. In the hallway, we want to widen the opening by about 20-30 cm and increase the height by about 10 cm. When I opened the wall, it looks like it does in the pictures.

The studs in the picture are 45x70 mm. The stairs go to the right in the picture. Up there are what looks like two "beams" that are 35x120 mm. They rest on half of the stud that is cut out. The problem is that one stud that is at the opening has the end of this "beam" (if it is a supporting beam?) on it. If I move it, it has nothing to support the end.

So do you think it is a load-bearing wall?

Thanks in advance!

Difficult to answer without drawings, but spontaneously I wouldn't tackle that wall, the beam looks quite suspicious.

Increasing the height of the opening is admittedly quite simple.

Yes, there are bearing lines on both sides of the post, so most likely load-bearing.

The height can definitely be adjusted up to the beam.

But if it is a load-bearing wall, do you think it's possible to widen it or is it too complicated? Neighbors with similar houses have a wider opening, but they may have reinforced it!

It probably depends a bit on how wide you imagine it, and the wider it gets, the more you lose in height. But maybe there is a construction drawing for the whole thing?

What does it look like on the left side? You can double the beam and screw them together..

Unfortunately, lacking such a drawing where you can see if it's load-bearing or not!

Is it possible to "splice" them together by doubling the load-bearing beam? How long on each side should you double it in that case?

Check if the municipality has the drawings, they should have them if the house is from the 70s. I wouldn't mess with it without a structural engineer's opinion. It's also a bit tricky that the staircase comes up right there. That pillar probably also carries some of the staircase's weight.

I thank you for all the answers and inputs! It really helps me to understand more

I managed to produce drawings and highlight the wall I am working on

If the ridge runs right-left in the drawing, it is normal for one or two walls that also run in that direction to be load-bearing. Then the staircase can also be attached to it.
