Hello everyone!

We were in the process of taking down some walls and came across a column of lecablock. I can see on the drawing that it is directly under a fireplace located on the upper floor, but it is also stated that it is a "future fireplace," some sort of fire protection?

What I'm wondering is if it's okay to just remove it? Or does it serve any function for the fireplace on the upper floor?

Ground floor:

Wall with exposed lecablock panels and wooden beams, part of a renovation project, under a fireplace mentioned in construction plans. Vertical section of a wall showing exposed cavity with lightweight concrete blocks, likely part of a support structure or fire protection under a fireplace.

The fireplace on the upper floor:
White tiled fireplace with decorative floral motifs, adorned with Christmas decorations, including a "Santa Stop Here" sign. Sunlight casts a warm glow.

Blueprints:

Blueprint of a two-story house showing living room with fireplace on the upper floor and a proposed fireplace area on the lower floor, circled in red.
Cross-section architectural drawing of a building showing structural details like truss and height measurements for first and second floors.

If there is a brick fireplace above the leca wall, I would assume it is load-bearing. I do not think you are allowed to place a heavy fireplace on a wooden joist floor today.

Yes sorry, now with picture :)
 
EDIT: Also uploaded a picture of the stove on the upper floor!

If it is specifically for the tiled stove or has some additional function, I don't know. But I find it hard to imagine that the wall is there for any other reason than to be load-bearing.
 
Placing a masonry fireplace on a wooden joist is idiocy. Besides, it is at least in Finland strictly prohibited.

If you don't find any load-bearing masonry underneath it, you should build something there. You should not touch the Lecamur.

Ok! Thanks!

But isn't it strange that it doesn't appear as load-bearing on the drawing (as far as I can see), and what bothers me is also that it is specified as a "future fireplace," and there is also a similar wall at the bottom of the image in the drawing that I can't see how it can support the stove on the upper floor at all? What do you think about that?

Ok, so I definitely should not remove the one that's there 👍 big thanks!

Still annoyed by the drawings.. :)
 
Find out if it bears weight. If it doesn't, it's a life-threatening construction defect, and then you must build a load-bearing wall under the stove.

Perfect, thanks!

If I dare to guess, there is something load-bearing and non-combustible between the two walls whose job is to support the tile stove. I think it's the fire department that doesn't like it when tile stoves fall through the floor structure during a fire.

Sounds sensible! Many, many thanks 🙏

It's also not very popular among residents when there's a fire behind the stove, and you have to jump out the window to avoid burning inside, shattering your knees in the fall. Wooden beams are too soft to place a masonry fireplace on. Sooner or later, the fire will escape through a crack. Such constructions were popular for a short period around 1900 but resulted in too many fires.
