I'm assuming the fireplace wall has no windows although it seems odd that such a long wall would have no windows if it is an outside wall. I would build cabinets on either side of the fireplace and house the TV in one of them, and make the other one a book case. I would put the couch facing the fireplace with the club chair at an angle next to it on the TV side. Hopefully there will be another chair at some time for the other side of the couch. You could have a narrow table behind the couch with decorative items on it to lessen the impact of the couch when you walk in from one of the doorways. There should be end tables at each end of the couch and of course a coffee table in front of it. If you put the TV between the doorways the couch will back onto the fireplace which would look rather odd, especially since furniture should be grouped around the main focus of the room, which is usually the fireplace. There could be chairs with small tables or perhaps a love seat near the windows at the short ends of the room for ancillary sitting areas. It would be nice to have photos of your room to get a better idea of your layout. Good look in solving this situation.

Sorry for mistakes in typing, hope you understand

Sofa on long window wall will look and feel the best and make the room inviting when you walk into it from the front entry. TV on the short wall opposite the sofa; pay to have the wiring redone and move on......you cannot make the space bigger but you can make work well....PS what and where do the stairs go? Do you have an upstairs? What are the dimensions of the living/dining room and kitchen.

Another render for perspective
