Edit: Will be repainting walls and trim to a lighter color to brighten up the space.

Hi HU - I thought this looked familiar. You have an older post and got a few ideas. At the time, I commented that I’d remove it. Now, seeing it again, I’d keep it - at least live with it for several months and see. It’s a bit quirky but gosh, that’s way better than boring, IMO. You can put a few well chosen items on the shelves and make it personal. I like it better seeing it this second time around 😁.

I would remove the built-in wall unit. It crowds that end of the room, and limits tv/furniture placement.

I would remove them. The space for the TV is too low (as evidenced in your pictures on prior post - coffee table blocking it) and will probably be too high if you remove shelves to accommodate a TV. Then decide on furniture arrangement to see if the TV is best to the left or right of the FP.

I vote remove. It feels off because the fireplace is right there beside it. The tv can still be on that wall but maybe on a low, simple stand.

Either remove the wall unit or the fireplace.
