Tear down the partition wall in the basement

[kalle_lidköping]

Hello! I would like some help. I am about to tear down an interior wall located between the boiler room and the hobby room in my basement from 1968. The idea is to create a large playroom for my daughter. But I am a little concerned about whether it might have any supportive function for the exterior wall.

I measure the exterior wall to be about 260mm thick and I believe it is made of hollow blocks. It is not cast.
The interior wall that I want to remove is made of blue concrete stone and is about 110mm thick including plaster on both sides.

I'm posting a picture with measurements to make it easier to understand.
What do you think? Can it just be demolished?

The hobby room is 374cm long and not 274cm*

Such a thin blåbetong wall is unlikely to be load-bearing.

What is the ground level outside?

 

[kalle_lidköping]

Okay, it feels good that another person also thinks it shouldn't be load-bearing or have any supporting function for the outer wall. Then the length measurement will be about 100cm longer than the recreation room. The ground level is about 170cm.

Then I had measured wrong. The interior wall is 9cm thick including plastering.

Along our basement exterior walls, we have a pillar built of polsten approximately every 5 meters, the pillars are about 200mm wide and extend about 400mm out from the basement wall.

Your load-bearing heart wall runs vertically, with the recreation room on the left side and the hobby room on the other side.

We have along our basement outer walls a column built of polsten approximately every 5 meters, the columns are about 200mm wide and extend about 400mm out from the basement wall.

Your load-bearing wall runs vertically, the rec room on the left side and the hobby room on the other side.

Yes, I fully understand that. Our load-bearing wall is 22cm thick, built with 20cm thick perforated brick.

But I'm wondering if the partition wall can support the outer wall in some way. There are quite a few cubic meters of earth pressing on it. But it doesn't seem like it can be that, given how thin it is.

Now the wall is torn down. It was only 7cm thick blåbetongstenar it was built with. Positive that it is a light material.

Late update but this is how it turned out in the Playroom. Quite liked by the neighbor's kids in the area, I must admit

But I need more help. I'm going to demolish more walls in the basement. They are marked with a red line in the first picture. They are of the same dimension as the one in the playroom. That is, 70mm wide blue concrete blocks. I don't think it is supporting the outer basement wall when it's only built with 70mm thick stones. Even less that it is load-bearing. In the family room, the lightweight concrete floor extends all the way from the outer basement wall to the main wall. I assume they use the same load-bearing capacity for the floor throughout the basement. So what do you think? Can they be demolished just like the wall in the playroom?

Cool, what kind of carpet have you put on the floor? Needle felt? I'm planning to put needle felt in my basement but I don't know where to buy it, Bauhaus is the cheapest but it's quite thin, but maybe that's enough?

Thanks! We bought it at Bauhaus. It sheds quite a bit, but there's quite a lot of traffic in there. But at least the concrete floor doesn't feel cold to walk on with the thin needle felt carpet.

Thanks! We bought from Bauhaus. It sheds quite a bit, but at the same time, there's a lot of space in there. But you don't think the concrete floor is cold to walk on with the thin needle-felt carpet on it.

Great to know, I'll try theirs too, it's so cheap that it would be worth a test regardless. I had planned to use their gray and dark blue variant. I was mostly worried about it being so thin, but it doesn't seem to matter. At some point, it will stop shedding, but maybe only the bottom will be left when it does?

Go for it! haha, but then you just buy a new one. As I said, they're cheap!

If you mean the first picture in the thread starter, I can only see one red line there, and that's probably the one that's already been torn down.

 

[kalle_lidköping]

Oops that image didn’t come through. Here it is!

Do you not have any actual house plans instead of an unreliable realtor's drawing?
