I would suggest moving your large television and its stand from its current position to in front of the fireplace opening. This will enable you to shift the couch so that one arm of it is against the wall looking out the french doors, one side still have its back to the kitchen table but people can enter the couch area from the French door side. You don't want to block a fire escape route. When family comes over you can put chairs in front of the fireplace bookshelf and tv corner cabinet and the french doors. With this new configuration you can install a large fancy or plan rectangle decorative mirror on the wall above the couch to bounce the light reflected from the french doors directly across the space. People feel uncomfortable with their backs to a doorway or other people. You need to add a console table and lamps or a dresser that is short and long to go along the back of the couch to create a protective feeling for people sitting with their back to the kitchen. For future renovations to the space you could install bookcases flanking the fireplace with windows above the bookcases or instead of windows mirrors that look like window. This could be as fancy or simple as you like. Disregard tv above fireplace in the image below put a mirror where the tv is to bounce light around the room and put the tv and its stand in front of the fireplace box so you can still use the mantel and when you want the ambiance of a fire you can have your tv project that image. Here are some pictures. I like the warmth of this mirror better than cold black but you get the idea also another place to decorate for holidays if you like, make sure the mirror is not too dinky.

What Jamie said. Unless you use the chair to watch TV. Right now, the chair is blocking entry into the room and the couch and chair are both too far away from the TV. So, TV to the left of the fireplace. Sofa facing the fireplace. Chair on the right of the fireplace. Bookcases on the wall opposite the window.

I am not a fan of these sectional pits but if you are are committed to all those couches in one room,I think I would consider one. I have never seen a room where the seating out weighed the TV/entertainment center, as yours does. It isn't working. Is that fireplace built in? It's so oddly placed on that wall it appears to be move-able. The TV and it don't work together. Perhaps they could be centered on adjoining walls?

Hi Katie, I'm Preksha and I've worked out a few layouts for you. The sectional you have currently is eating up a lot of space so I would definitely recommend breaking it up with a sleeker couch and a couple of chairs. Although it may be a little tight, placing the TV on the large blank wall and a couch in front of the slider gives the room some intimacy. I would also recommend adding a tall bookcase and a media console with some storage. I've also worked on another layout with the TV over the fireplace as @groveraxle suggested. You can add some storage on either side of the fireplace and replace the armchair that is now there if you would like more seating. Would love to help you with more layout/ furniture suggestions, do let me know if this helps. You could get a clearer look of these rooms and can customize them to your liking here.
