Tear down part of the chimney

[niklo]

We will soon be moving into a house built in 1922 with the classic solution of a central chimney. The thing is, the chimney is L-shaped where one "leg" contains the flue for a working tiled stove, while the other only contains flues used/can be used for ventilation. As part of the renovation, we want to squeeze a shower into the downstairs toilet, which is surrounded by the chimney on two sides. To gain more space and utilize the area wasted by the unused part of the chimney, we are considering demolishing the unused "leg."

What do you think? Is it possible? Could there be a problem with the stability of the other "leg"?
Of course, the floor structure will be supported there/if necessary.

Thanks in advance for any opinions

Since there is compact silence, I'm brainstorming a little myself.

I've been thinking a bit about how to proceed, and chiseling quickly comes to mind. The downside is that you will definitely crack a lot of joints that you don't want to mess with. Then I thought about combining the chiseling with making cuts with a circular saw to get manageable blocks that are somewhat isolated from the rest of the chimney.

Does anyone have any thoughts on that?

I can't speak to the suitability of removing part of a chimney, but it sounds risky. However, I did demolish a masonry fireplace in my living room. It was quite dusty, but it mattered less as I was planning to renovate the rest afterward. Lay chipboard on the floor if you're concerned about it. Encase the work area in plastic and tape the seams to minimize dust dispersion, and have a shop vac with you. For me, a moderately sized hammer drill for under 1000 kronor worked well for breaking. The bricks usually come loose with a few taps. Only use the angle grinder (with a diamond blade) when bricks need to be cut. It's the angle grinding that creates dust. Get a good breathing mask; that white paper kind surgeons use is probably too weak. Good luck, but first consider what will happen to the rest of the chimney if you remove part of it.

How did it go with this?? I'm facing exactly the same dilemma, I want to tear down a "ben" and hope that the rest of the chimney remains intact.
