Thank you for the visual!!

Is that a TV over the FP? Sofa facing FP; loveseat in front of windows; antique cabinet where sofa is now centered. A small scale swivel chair on each side of antique. Tall art in alcoves.

Yes, it is a tv. Thank you for the ideas!

You can create photo galleria on the wall, even put some side board under.

Agree with celerygirl - a credenza on the left side of the fireplace; something with visual weight to balance the tall cabinet on the right side. A lamp on top.

Here are examples of how other rooms have accents the walls on either side of the FP.

I filled in room with rug, coffee table, side tables and lamps.

Yes some kind of credenza

Do you have a dining room for that antique piece? I would place the sofas facing each other 18" from a large coffee table that is centered on the firebox. Then add a pair of chairs at the end opposite the FP. In the two niches, I'd prefer a pair of matched chests or consoles and art. The grouping behind the sofa should be tightened up and hung in a hallway or mudroom. Its too casual for the look of this room.

OMG! Deco nailed it!

I am not so good in furniture layout, so I used her advice. I like this layout better.

I think this view would be better

In the last picture, TV viewing is not optimal with the couch and love seat at right angles to the TV. I'd also suggest a more colorful rug so as not to drown in a sea of neutrals. The original art on the left wall is hung too high and also does not have enough impact for that large a wall. I'm afraid words and letters are a trend that has had its day, and this room would also really benefit from more color. If you really want your antique to stay where it is, celerygirl's idea of a credenza with art on the other side is a good one. It actually gives the room more interest compared to two identical modern pieces on each side. An Oriental rug would go well with the antique and give the room warmth and character.

Rearrange the room and put the TV here:

Unfortunately, the tv cannot be moved. Also, the wall length on the opposite sides of the room are not the same due to an opening to the foyer. I originally had wanted the loveseat & sofa facing each other but because one wall is shorter it forced everything to be pushed down towards the fireplace and off centered.

We live in a world where the TV exists, to pretend otherwise is silly. Your TV is placed appropriately. I am rather surprised at the matchy matchy suggestions. I like the antique piece, a surprise in your modern room. The predictable choice is a bookshelf on each side of the fireplace. I vote for the gallery on one and the antique piece on the other. It will be a conversation piece for sure!!

Consider the FP/TV as your centering point, not the walls. It will seem "off" because the seating won't line up with the window or the short wall, but if done right, it will become such a focal point that the walls/window won't impact it. If that doesn't work for you, I suggest the larger sofa be placed facing the FP and the shorter one right or left of it.

OK, if the TV has to stay there, then let's showcase the great antique. You don't have to till all the space on the sides of it. I'd center it on the portion of the wall from the doorway to the beginning of the alcove.

Thank you for the visual! I love that you added an extra pup!
