I would get a contractor in to see about removing the stove and jackhammering out the raised section and reflooring the entire basement. Ask for how much it would cost to remove the brick vs patch the section where the chimney is. You'll gain so much useable square footage that it could well be worth it and it looks like the carpet needs replacing in any event.

I would start by removing the "fencing' and take a photo of all the pieces for resale.

you may be able to recover some of your reno expenses...

I am guessing the "hearth" is just slate on top of a framework platform, Once you take the weight off it, you can pick up a piece and see.

if the carpet has been replaced since installation, you may need to replace flooring after the removal. Or it's all sitting directly on the carpet. Looks like a project worth doing. You'll recover some great space. You may get away with hanging a framed piecture over the venting hole.

Carpeting is very worn out by the two teenage boys that live there! Definitely needs replacing, but we were waiting till we decide what to do with the stove.the railing is collapsible, so that’s no problem. Thank you all for confirming what I was thinking of doing.
O problem.

Chances are the floor is concrete but removing the hearth will be a big job for sure and removing the stove will leave a hole in the brick too.. Katin has some good advice but I do not think the stove would meet new code now so selling not reality/

If you remove the platform, it will be the perfect opportunity to replace the flooring all the way to the wall. The brick wall could be a pretty backdrop for artwork or some kind of storage if you need it. You might want to think about replacing the carpet with LVP for easier care and using area rugs to warm up the space.

Agree the brick wall would be a nice backdrop. Some brick isn’t so great but yours is.

I personally detest carpeting. I also suggest some type of vinyl flooring. There are some beautiful sheet vinyls (minimum 10 mil), VCT tiles, laminate tiles (below grade rated) that look like marble, etc. VCT have the color and pattern all the way through so small scratches don't show. Make sure to put down a self leveling compound, and a heavy duty vapor barrier first. If the basement is not drain tiled, you might consider doing that in the process too (the dehumidifier is a sign it's needed). When I pulled the old 1968 VCT tiles up and put down ceramic tiles my basement became excessively humid, wasn't before. I have 2 dehumidifiers now. So now I am probably going to pull the ceramic tiles, drain tile the basement, and waterproof from outside for the 3rd time. I will likely put in sheet vinyl or new VCT. Wish I had left the old VCT and just waxed it. Vinyl is kid/pet friendly. I do light colors on flooring - really brightens it up. Good luck with your project. I tend to use skilled handy type men who people I know have used. Have whom ever you hire do a small project first to test their services.

People with cabins or lake houses will buy the stove. they don't come cheap.
