The problem is obviously all those doorways. However, I would ignore them in terms of placing furniture and put a comfortable chair on each side perpendicular to the sofa. As long as the chair is small enough that you can easily get around it it's not going to matter if it partially obstructs the doorway. You want to have a U-shaped configuration so that as many people as possible can watch TV comfortably. You'll also need side table between the couch and the chairs in addition to a coffee table in order to make the room look furnished and so that people can place their coffee cups, dessert plates etc, somewhere. You might want to see if there's enough room on one side to place a small loveseat which can seat one adult and one child to increase seating. I would strongly consider a large area rug to lend some softness and color to this room which has so many openings with the bare windows and three large doorways. This will make the seating area look more finished and cozy rather than just some haphazardly placed furniture. More pillows would also be a good idea to soften the scheme and give it some cohesiveness, with the pillows picking up some of the colors of the rug. Colorful and interesting wall art would be a necessity to finish off this room, with more furniture (bookcases, desks, a secretary etc.) against the walls.

Here's a more accurate room layout with the dimensions of the room and recessed area for the TV. The very simple website I was using doesn't really let me specify an open archway or change the layout of the walls to reflect the recessed area in the corner with the door, but I don't think it matters much. I'm more concerned with having seating for at least 5 people, not obstructing the window view, and giving everyone a good view of the TV. I was thinking perhaps the chair on the left should be a swivel chair, to allow someone to turn and watch the TV better. I could do without the chair there at all, but would like to have family over on occasion and it would be nice to seat more than 4. Do you guys think this would work?

Thanks all again but after being in the space and testing out the layouts your offered, I really do prefer the TV in the corner so I'm trying to decide between one of these 2 corner TV stands: https://www.birchlane.com/living/pdp/pullman-corner-tv-stand-for-tvs-up-to-65-b001030194.html?piid%5B0%5D=1082005253 https://www.birchlane.com/living/pdp/birch-lane-heritage-benedetto-corner-tv-stand-for-tvs-up-to-65-b000771980.html Thoughts? Then I can put an upholstered storage bench underneath the big window and a console/desk behind sofa with chairs for extra seating. And I still want to get a chaise lounge or armchair with ottoman place counter the sofa (empty space in mock up below). *Mock up is not the right colors or styles but just picked based on size to help with figuring out layout

Ok..so with the TV staying above the fireplace and the need for more seating…instead of a 3-seat sofa, I’d suggest getting the largest sectional that will fit properly in the space (hopefully 4 seats along the back wall, 2 adjacent seats on dining room end, and a chaise on the end near the front door. In the meanwhile though, the current furniture could be rearranged to work with the current seating or new seating, once it arrives. Remove the wooden bench, firewood hoop, and telephone seat, and rectangular end table. Move the entry console to the left of the fireplace and the smaller console to the right of the fireplace. Move the current sofa to the right a bit so its end aligns with the end of the wall. Then place the round end table on the left side of the sofa and place the chair right next to it. Then move another chair next to it…just to get an idea of the footprint of the sectional I described…then assess and see how that feels. If it’s too tight, then maybe just another chaise end on that end too. (Hopefully one of the Pro’s will post a to-scale furniture layout.) I’m glad you said you will be redoing (or restoring?) the fireplace…the gray stacked stone does not belong there. Medium toned paint color for the walls…to be determined after all furnishings are in place.
