Hello, I am going to demolish 2 walls on the ground floor of my 1.5-story house.
1 of the walls is non-load-bearing but has a column in it, the other wall is load-bearing (I think?) and also has columns in it.
I want to remove the column in the non-load-bearing wall and demolish the load-bearing one but keep the columns.
How should I proceed to shift this?
Red line is the wall I think is load-bearing and want to demolish.
Blue line is the wall that is not load-bearing and shall be demolished.
Yellow arrow indicates the column I want to demolish.
Purple line shows where I assume the beam should be.
Does this work or is it just to forget about it?
Regards, alex
Is it possible to open the floor and recess it? Then you can decrease the building height of the beam downward.
The wall section to the left of the blue wall should remain? There you will have a pillar in the wall, so the free length is a bit shorter than the entire purple, which is good.
Alternatively, if you can have cross interaction on purple and blue, but it is much more complicated to calculate and build in.
That is, recess a 260 beam in that compartment in the floor and let the purple hang in the blue.
What type of foundation do you have? It will cause a very high point load that you need to consider with some form of pillar or new casting.

In other words, recess a 260 beam in that compartment of the floor and let the purple hang on the blue.

What do you mean by opening the floor and recessing it?
The wall to the left of a blue will remain, yes.
Foundation?
Do you think the red wall is a load-bearing wall as I believe, or is it not?
Why are there 5 parallel columns through the house? Aren't those the load-bearing ones?
What are we talking about for a beam?
HEA? I want to come down as much as possible in dimension.
I had probably assumed that the dashed longitudinal line has a load-bearing function. That means, in that case, there is a beam diversion in the roof above what appears to be marked as a garage. Similar diversions can of course be made along the rest of the stretch if there are columns that bear at appropriate distances and the slab beneath the columns can handle the point load. But check with a structural engineer.
Okay, thanks for the response.
Is it then safe to assume that there is also a beam above the red-marked wall?
That section is dashed too.
So the wall is not load-bearing but there is a load-bearing beam there?
So it feels like a deadlock to remove the pillar with a yellow arrow?
If you take the marked column, you'll have to consider replacing the beam all the way, which could be quite a hefty piece. As someone mentioned, the dashed lines are likely a reinforcement or footing in the floor structure. The fact that it's there and how it looks might suggest that the "red" wall has roles other than just bearing weight; it might stiffen the construction and be a bit more challenging to remove. Definitely something you should discuss with a structural engineer and get documentation on before proceeding. You can get a lot of help on forums, but you also need to filter through the advice (even mine, as we all make mistakes sometimes). My initial thought is that it's a massive task ahead of you if you want to do all that without the column. But sometimes, it's fun to work!
I would never ever start tearing down pillars/walls here without having brought in some expert on construction... my and others' opinions here on the forum are worthless, since none of us have been on-site and checked the actual facts
Thank you so much for all the answers!
One more question, I am going to move the entrance door from its current position (hall 001) to where the window in the bedroom (002) is located.
I will brick up today's entrance opening.
Does this work construction-wise or do I need some form of header here as well?
We don't know what type of facade material you have and so on, but as long as you stay within the window dimensions and not make it wider, there shouldn't be any issues.

It is mexi brick and the house is from 1981.
The opening will be 20 cm wider than the current window.
