Lol unicorn. Is this room going to be used for a t.v. or just a living room and what is your plan for the second part of the room? What is the function you need. In a long room I prefer to float a sofa or two chairs so the first plan would be my first choice but across from the sofa I'd put two swivel chairs with a table in between. I don't like the one with the sofa in front of the window. Will you need more seating at the other end? You could put a game table and chairs there for eating and playing. Will you be using these two rooms primarily or do you have a family room?

Baunlee, I once had a 13x21' living room in a Mission style bungalow in West Hollywood. It would have been a very nice room except that the front door and wide arch to dining room sliced it right in half. You don't have that problem. This is a nice room.

Apparently those photos are distorting the proportions, and probably that extremely...unfortunate "division" a PO installed. Reuniting this nice room with itself would be my own priority by removing all that wood ASAP.

But for immediate furniture placement, I would not divide the room into two small, unrelated areas by running a sofa, or anything else across the middle. Turning your back on others and not having anything to do with them is not an embracing and uniting use of furniture, any more than it is in people.

You want to use the entire room, make if feel large and all corners vital and inviting. That means the two areas of use should allow open and inviting flow between, with just gentle definition of each area by such things as easy chairs, small tables, upholstered benches, that sort of thing.

You seem to watch your TV from the sofa, which means for now it would have to go in front of the main window. I'd put the other one on the short wall at the other end of the room, replacing it with an upholstered chair or chairs. (The kind of sectional that has a backless lounge on one side would also work here, since the backless portion extending across the room could serve both sides in a very friendly and functional way.)

I'm with you, though, in preferring not to block the window with the sofa, and it would be my preference to set it on the inside wall opposite the window, with TV on the short wall right of the bedroom hall arch. This would also allow someone doing something at the other end of the room (maybe on the other sofa) to keep an eye on it. Traffic from the bedrooms would have to swing around the main sofa a little bit, but big deal. :)

If you take the paneling down, you would probably take the wooden arch down also and then the room would look like one. If you wanted to leave the wooden arch (for want of a way to describe it) you could make that part of the room the dining room. Then #1 would be my favorite, but with the easy chair (that you picture behind the divider) facing the window so that you could walk behind it. If you have a dining room already, do #1 but put two easy chairs with a table for a reading area and maybe some book shelves.

I don't think the fact that the bedroom is off that area is a major concern, except that I probably wouldn't put a tv or stereo directly against the bedroom wall for noise reasons.

Much like grandmaof3 above, I thought this might be a good opportunity to add a dining area, if you don't already have one. The paneled area appears to be just right for it. If a dining area wouldn't work, maybe a den or library area. You could set a writing desk perpendicular to the wall where the chair is in plan #2, which would divide the space but leave it open.
