It seems like a big enough space that it will always have two functional zones. However, I think you could widen the seating area around the TV, and then put something else at the fireplace end, like a couple of arm chairs with a table between them (for rading or watching the fire), or a game table with a storage cabinet.

For the main grouping, I think I'd put a couch facing the TV (or at least the wall with the fireplace on it), and then a chair in front of the window and one or two more facing the window. You'll want a much bigger rug, and a couple of end tables with a lamp or two. You can push the couch a little farther away from the walkway to the bathroom (?) if it's not part of a sectional - the chairs work better for conversation too, and allow a variety of TV viewing angles.

We have a room a bit like that. We put a drop-down screen on the beam between the 2 zones and a projector on the ceiling. We also have some swivel chairs between the two zones, so they can be part of either grouping.

Awesome! Thank you for the feedback! Do you have a picture of your room? I think it would help me to visualize the grouping.

Would you be able to add more photos of the fireplace area with the sofa or loveseat in it? We need to see all of the walls in order to be able to give you a proper layout. We would not recommend a sectional at all in this space unless you end up getting an apartment sized one. Below are some living room and family room designs that might help you more.

Sure wish we could be there in the room to do the measurements ourselves but because we can’t we really need your help so we can give you some suggestions. May we have measurements of the room with openings, windows, doors, fireplace, and the couch. Rough hand drawn sketch with the measurements added in works really well. That will make it easier for us to help offer suggestions. Otherwise, sometimes suggestions can be offered, but the furniture won’t fit the room. Thank you in advance.

In addition, how many people use the room daily and how many guests do you want to accommodate? Also, do you like to have game night and play table games?
