The fireplace seems centered on the wall. If you arrange your furniture so that it is floating and centered on the fireplace it would all balance out. Building shelves there will make it less balanced.

I'd be tempted to remove all the stone above the mantel, and then put the TV to the right of the fireplace over a console -- that will put it down at proper viewing level and make the wall feel more balanced. (balance, not symmetry, is what makes spaces feel right.)

The fireplace looks centered on the wall. TV is much too high over the fp. Probably best to get your furniture in and then reevaluate.

Here are some suggestions for you.

Agree TV is much too high over the fireplace. However, Beverly's mockup is a good solution if the TV has to stay there.

Some ideas

I like Grover’s solutions.

Celery girl shows great ideas - ideas we are exploring. I do not like TVs over fireplaces. Usually they are too high. I think shelving plus tv off to the side is an excellent solution. It allows proper height for viewing plus shelving for books etc. to add interest to the wall. Right now it is not working and just looks strange with the upper curved brick portion of the fireplace and too narrow for the space.

Definitely liking grover's example.

The TV belongs to the right of the fireplace.

The TV is much too high for relaxed/ comfortable viewing. Put it on a swing arm to the right of the fireplace, and get rid of the cute brick surround.

Is there an upper level window that we can see? From the posted picture, the drapes look overwhelming.

Thanks everyone! Yes, the fireplace is centered in the room but not to the established wall since there is a doorway into a bedroom. So even though it’s technically centered, because of the doorway on the left side of the room, the sitting area is not centered. Originally, to fix this, we were thinking of something similar to this. Thoughts?

@jbtanyderi Yes, the windows on the left go all the way up the room, 20 ft ceiling.

LGaustin, I don't see that your last photo fixes much. In fact, I find it more awkward than the current situation with the TV over the mantel. The TV belongs on the wall to the right. Just balance the portion of the wall between the door opening and the corner.

To the right and at the right height.

TV To the Right, lowered for better viewing. Celery girl and Groveraxle gave better fixes than your last pic, which looks very awkward. Good Luck
