geokid, that is actually what I think my husband and I will be doing! What a coincidence! Over the weekend, we tried almost all the layouts suggested (much to my husband and everyone who had to help's horror), even went back and forth a few times, and have settled on two arrangements that will work best for us. In either arrangement, the sofa is going to face the fireplace. We'll have two slimmer side chairs with a opposite from the sofa. We most likely will have the TV mounted on the long wall with a smaller cabinet or mounted cubbies/shelves (something) for the electronics. I might add in a small tufted bench opposite the TV if we need more seating, but the two side chairs should work for now, and when my family/friends come over to play video games (which seems to be really often lately), we'll pull the chairs over. But realistically, we all sit on the floor. The piano will stay along the stairs, and to balance the open wall space between the piano and the sofa, we'll mount some shelves for decor and books. We tried mounting the TV over the fireplace, and I surprisingly liked it, too! It totally cleared up the floor space and made everything so open, but...it was kind of uncomfortable to look up at the TV. I'm only 5'3"; I don't mind a few minutes like that, but not for a couple of hours and not for game-playing. It's fine for my husband, though. I'm still keeping this an option, as I think we won't really know what'll work for us until we start buying some new furniture. I tried placing the piano in the dining room; no good because it ate up too much room. The bookcases are currently there, and I kind of like it! LOL. We have no dining table yet, so it feels like a special reading room. Haha! I like the idea of the bench along the window. If our chandelier was centered in the room, would it look weird for the table to be off-center? Otherwise, my plan was to buy a narrow table, have bench seating on one side (probably closer to the bar area) and regular chairs the other side.

One idea might be to add a very short wall on the left as you enter the living room so the opening to the living room is the same width as the entry ... and, by doing that you could put wall to wall built ins on that end of the living area, with or without a tv, and still create two separate sitting areas. I don't understand the "bar" against the solid wall behind the pantry and refrigerator. If you changed the pantry to a "butler's pantry" with a pass thru window, that would have made more sense. Is your "bar" a cabinet something built in? Have you considered either closing or narrowing the door between dining and living room and/or creating your pass thru bar there with your piano in the adjoining corner adjacent to the fireplace near the dining room wall? https://www.decorpad.com/search/butler-pantry-pass-through

It's gigantic. I'd be trying like hell to avoid that. I'd use the dining table in the dining room for a combo desk /office. I'd buy more flexibility.......comfortable flexibility. A tv can mount flat to the wall, With an IR repaeater, it needs no console beneath. The cable box can go anywhere. I'd get a nice deep and comfy 84 inch sofa, put a console with lamps behind. Add two super comfy chairs and ottomans. A nice generous, light and open cocktail table. Lie down! watch the tube! Put your feet up! Add a little ottoman for a perch at the cocktail table. People love to sit and reach a snack. Add a low table between the chairs at the fire......open and light. Ten x 14 rug to ground everything. ( dotted line ) Go set yourself up in the dining room, to work, and just clean up when you have guests !! No matter the sprawl, no more than three folks will ever sit on that beast of a sectional : ) Two chairs and a total of three ottoman plus at least two on a sofa............for gatherings gives you seven seats. A smashing piece of art over the fire too.

can you put dimensions on this plan and if possible some images of existing place
