Use a corner unit for the TV

I would move the TV to the wall where you have the wall sculpture and put a credenza under it that is at least 25% wider than the TV. Turn the sofa and place it under the yellow art, facing the patio doors so all 3 focal points are in view from it. Perhaps the 1.5 chair will fit on the wall left of the vertical window. If not, eliminate it in favor of another chair like the small one, so the two smaller chairs can float and be flexible.

What is it you're trying to fit?

my husband says the sofa against the back wall is too far from the tv, leaving so much space between them. so much empty space in the room. so he moved the sofa inward, making it look odd, now there's so much space behind the sofa. that's the issue, making it a living room, comfortable, and good use of space

The length is 17.5 ft....I need an enormous tv in that case

I like Beverly’s idea. Have you tried that? You put a sofa table between sofa and wall so it’s a little more forward

Maybe all you need is a larger TV stand. Your TV looks enormous under the current one.

that stand is a placeholder. we hate it, can't wait to throw it out
