I think the piece the TV is on would feel more at home in the basement with the chunky coffee table. Your home looks to be more contemporary in style except for the stair railing and the big empty display/bookcase. Do you have the budget to remove the built-in? That would give you some wall space for furniture and art. What is the exterior style of your home? Can you pull off a contemporary interior design and not stray too far from the look of the house outside? I don't think the DR is large enough to add more furniture there. I suggest a great piece of art and a rug that is 36-42" larger than your table top on every side. Pull the same colors into the LR with big art on the wall opposite the FP and above a 3-seat sofa where the built-in is. You can do another rug in the LR that is similar in style and color to the DR rug. For example, here are two navy rugs that could work together. The top one picks up your wall color, and the bottom one picks up on the fireplace stone.

Cute place, i see the challenge, but I am really against a sectional in this space let alone for guest to have to sit next to each other it creates a weird dynamic. I hope you are not planning to put the tv over the fireplace that would also be a neck breaker. I see the couch on the side the two red chairs. the tv on the wall with the lockers and 2 chairs to the dining room side.

Sorry, not sure why the picture didn't post. Here it is again. RL, I like the round pendant and the pleated one in your first set of suggestions. Is that a Nelson bubble pendant? Also, I should have given a few dimensional details. The table is 36" wide at the ends, 40" wide in the center. Ceiling height is 92".

Living room dining room combos make me really happy. How many in your household?Do you eat at this table nightly or most commonly eat in the kitchen? Do you sit at this table and do other things like projects, kids with homework, gather with friends? Do you have another living area in this house that you chill out in or is the seating in this room going to be the makn ha g out space in your home? Who will sit here and when, what time of day, to read, be with guests, hang out? I’d love to see the table turned 90 degrees so it is parallel to the window and living in that area next to and along side the window. It just makes sense to me for the layout and lines of this room. It may or may not make sense though for who uses this space and when. Main question, do you want the daylight and view from the window to be enjoyed as a table space or sofa space? The buffet /cabinet is a great piece but looks super bad next to the wood where it is currently located. I’d put it on the long white wall near where your desk is currently located and use it as a visual bridge between you window/dining area and a sitting area where your sofa is currently located. Light fixture is fine where it is do not use it to determine furniture zones. Stone area is a lot of look. Don’t put furniture or other things over there. Just give it space to be what it is. Nice that you dont need desk, piano, or TV in here.
