There are also walls that are not load-bearing, but do provide bracing if I am correct. I'll put it this way: probably nothing will happen, but if it does, you will never be happy again for the 600€ saved.

It cannot be ruled out that this wall is load-bearing or at least bracing. Providing support for a steel beam in a one-brick thickness wall may require more than just a deep embedding of the beam. It may become necessary to use stones of higher strength under the beam. Without a structural engineer, it is not responsible to plan this. Overall, I would recommend a thorough investigation of the entire structure. Also, to avoid being unexpectedly confronted with risers or downpipes in the middle of the beautiful opening.

The wall is made of plain bricks. Unfortunately, I assume that the wall is load-bearing. Here is a simplified floor plan (I hope the resolution allows it). The basement consists of 240 mm walls. Above that (except for the shafts) are 115 mm walls. Above the wall where the lintel is to be installed, there is a wall of the upper floor.

I don't want to save in the wrong place, but also not spend unnecessary money.

There are no risers or downpipes in the wall there.

Klaus

The section indicates that there is a wooden beam ceiling between the ground floor and the upper floor, and thus all those walls that continue into the upper floor are indeed "load-bearing."

According to the representation, the basement ceiling is made of concrete. This should allow the wall remnant to support a steel beam as intended. However, I anticipate the necessity to initially make the opening wider and to rebuild under the beam's supports with KS.

An alternative could—depending on the importance of this wall (on the upper floor) for the roof structure—be to also demolish the wall on the upper floor and rebuild it as a lightweight wall. That means, if necessary, practically: consulting a carpenter on how to support the roof structure down to the basement ceiling. This can influence the location of the desired opening.

You guys here are simply the best!
By KS, do you mean limestone?
I would rather not break out the wall in the upper floor, but the lightweight partition wall still makes sense.
Thursday we're going to the notary, then 2 weeks to the Canary Islands...

The work will then start at the end of July and I will definitely give feedback on how it was done.
I will definitely consult a structural engineer for advice.

Yes, although bricks with increased strengths are also available. Under the bearing of the beam, there is partially more pressure than with a "uniform" wall.


As I said: first explore the correlations with the roof statics. The section indicates interrelations there. A carpenter should take a look at that.

The brick format used suggests a construction year from 1955 onwards, but the construction style is partly probably more traditional than the then current state of the art for reasons of economy.
