ᐅ I need help with wall removal.

Hello everyone.

Brief introduction: I just became a member of hausbau-forum.de. Two weeks ago, we bought a small house built in 1926. Now I'm at the stage where I want to remove a wall.

So here is my question: Would it be enough to support the wall with a beam approximately 12x16 cm (5x6 inches) underneath, resting 47 cm (18.5 inches) inside on the wall, and to place a post sized 12x16 cm (5x6 inches) below on the exterior wall?

There is already a ceiling joist of 12x17 cm (5x6.5 inches) on the wall, upon which a thin wall made of tuff stone is located on the upper floor.

The upper part of the wall also includes part of the roof structure. I’m not concerned about this, as the loads are transferred to the exterior wall.

Here is a picture of the current situation:

Additional information will be provided if needed (want to save myself some typing 🙂)

Thanks for your help

I hope someone with structural engineering expertise will respond.

And if there were a structural engineer here, they would know never to make remote diagnoses!
So forget relying on any forum or online inquiries for this matter and find someone who can inspect your construction site in person.

Oops, I just received a warning because of the link. 😡
I actually thought it was the other way around: if you post an image (screenshot), you also need to provide the source or link.
Okay, lesson learned 😉

Now back to my question: Of course, you can also give a recommendation remotely.
The situation is clear (plans, pictures) and fairly straightforward.

Even with new builds, not everything is always calculated. There are general recommendations because many applications have been calculated multiple times, and often standard dimensions are used.

Someone who, for example, has already removed a wall under an existing beam above can tell me which type of beam was used.
Such answers will help me much more than well-intentioned advice to consult a structural engineer.

Thanks and regards

The situation is clear (plans, pictures) and quite simple.

Hello Sicky,

If the situation were clear, you wouldn’t need to ask!

I also started renovating a house from the 1910s-1920s two months ago, and I removed walls too (one long and two short ones). But without a structural engineer, it would have gone wrong.

Although I never intended to avoid consulting a structural engineer, I did think ahead about what I would need, and I was completely wrong—fortunately for me, as I had anticipated more effort than necessary.

Regarding remote diagnosis: If I, as a professional, make a diagnosis online and something goes wrong afterward, the professional faces serious legal difficulties. For that reason, nobody will likely want to put themselves in such a position without payment. Furthermore, in structural engineering, you always have to consider the entire building—not just one wall that is supported by another.

So: Don’t cut corners in the wrong place!

Best regards

Thank you, K.Brodbeck,

yes, I will consult a structural engineer.

Nevertheless, the opinions from the forum members were very important to me.

I already expected an answer like "Use beams 12 x 15 cm (5 x 6 inches)."

Only now have I realized how delicate the situation actually is.

Thanks to everyone.

Hello,

my wife and I are planning to have a wall removed. However, we don’t know any specialists in Tübingen or the surrounding area who could take on the job. Does anyone know a reliable professional? The budget is not a major concern.

Thank you in advance for your help.

I was hoping for a quick response, but I have already started searching online. I came across a clearance company that also demolishes walls. They seem quite reputable. Let’s see how that works out...

I am still open to new ideas...
