It would help if we had a better idea about the orientation of the rooms -- the space you have available. I agree with those who suggested you consider swapping the functions of the rooms -- make the existing dining room the TV viewing room and move the DR table to another room (LR or FR). Failing that, is it possible to extend the feed from the security cameras to a location where you would actually want to sit and watch TV? Failing that, could you purchase a nice tablet for hubby that he can have with him anywhere in the house, so he would have ready access to view the security feeds? After all, I would think the need to view those feeds is momentary at best -- watch a movie, pause the movie to check cameras for a second, return to movie -- right? He's not going to actually sit there and watch the feeds for any appreciable period of time, I would think (although my father can sit for appreciable periods of time watching the Weather Channel, so what do I know?).

So, it's 15 ft from window to fireplace? Is that the entry to the left of the fireplace in the last pic? That first pic Rawketgrl posted shows the seating area on an angle. That might work well in your room so that the piano and fireplace can be the focal points. An upholstered chair and table can to go on the end by the window. I like Acm's idea to bring in a game table, which can be just to display a few things if you want. The couch can be perpendicular to the fireplace, with the bookshelves behind it and couple of chairs facing the fireplace. Or, turned 90 so that the couch faces the fireplace. Chairs on one side, or both, depending on the room available. A table can be by the windows for display of some pretty things or used for games. Plants, tables w/ lamps to fill in the holes. A large rug will anchor your floating seating area. My combo family/living room is similar in size to yours. My seating area floats in the middle facing the fireplace, which is on the long wall. The back of my couch faces the entry because the shorter direction didn't give me enough room for my couch and tables. Around the perimeter is a huge lighted cabinet, a table with lamp, and two dressers that hold music/media with the tv on top.

Well, I certainly couldn't have done ANY of this without all of you. I am so happy looking around my new rooms. My favorites: the furniture placement (of course), the art wall, the mantle, the 3 vases on the black tray on the table (although there may be too many flowers in them at the moment), the fabric covered shade in the dining area. the sofa table bookcase, the fireplace screen... I'm going to interrupt myself because now it seems I'm just listing all the changes. It's obviously too hard to pick just 2 or 3 favorites. Theresa, your peonies are gorgeous -- loving the size of those blooms! I hope to follow all of you as you move on to new projects. I consider each one of you a new friend.

West Elm and other sites showed to do it like that, it doesn’t make sense to me either. Weird I am not brilliant in math & i am a new home owner I never cared to decorate apartments and damage furniture in the move so now i am trying to make this house a home. I was never bright in math. Thnx though
