Is that a mantle that I see behind one of the blue sofa's, if so, the room might be facing it with a different couch formation.

I would push everything back towards the wall in question. Add a sofa table behind with art above. OR replace the current console with a much larger one, change the mirror for art, and center all of the art in the space above the console.

I think a large, vertical piece of art could work there on the wall if you can find something you really like.

That spot in the corner is PERFECT for a chaise lounger with a little table or bookshelf....but you don't have enough space. The sofa is blocking that area from being usable. What is pushing the sofa into that space? The coffee table. Yep. If you narrow this down to space occupying items, the coffee table is causing an issue with space.

Personally I love the look of your sitting room, but right now the coffee table is taking up too much space. If you brought in a narrower table, pulled the sofas a little closer to each other you will open up that extra 1-2 feet you need in the corner to add in a functional reading/lounging nook.

The shape and colour of your furniture allow you to utilize a super cool, curvy modern chaise while still keeping the space functional and open. Sadly the size of the coffee table is limiting the use of that one corner.

Use a couple of plants to divide the dining room from the living room.

Use cabinets with doors, or a hutch or some type of closed bookcases.

update: this is the living Room. On the other side of the dining room table is the family room which is all open. Also the coffee table doubles as a game table and is hydraulic with seats underneath which is why need to keep it even if it isn’t the most aesthetically appealing.

You need height on the far end of this room. I would remove sofa near fireplace and get two small scale swivel chairs that could swing to fireplace or to conversation/game area.

Something like these.
