What a lovely room-- I can see why you'd want to spend more time there! Are you open to rearranging furniture? I'd float the sofa in front of window with the chair opposite.. then put the tv (assuming it's a large one) on the wall behind where the sofa is currently. I have my tv over the fireplace now and I hate it.. it's the best place for it but it completely sucks the charm out of the fireplace. And yes--it's too high. If you are thinking a smaller tv.. then you could probably keep your furniture arrangement and look for a small cabinet-- perhaps on rollers-- that would disguise the tv and allow it to be moved as needed. The shelves are a great spot for a smaller tv-- but I fear they are too far from the seating for comfortable viewing.

Post pictures of each wall in the room. Not curved, straight on.

I would keep this basic arrangement with a few changes: 1. Whatever is in front of the fireplace needs to go. 2. Move the tree someplace other than this room. 3. Put the two red chairs together in front of the railing and send the recliner to another room. 4. Get matching floor to ceiling curtains for all windows in this space. 5. Get a rug large enough to hold all front feet of the sofa and chairs. 6. Replace the current console with a longer one that spans nearly the width from fireplace to wall and is no higher than the one you have now.

Thanks to both of you! I don't have access to a floorplan, unfortunately. Also unfortunately, I cannot do any major work at the moment, so the ugly mantel stays (and I did not even notice until now that it doesn't match the fireplace!) I would love to put up some artwork, plants, etc in this room as well, when the big pieces are settled. Already thinking about drapes but very little clue where to start - this side of the house faces the street so I really want to get some noise dampening ones, although they would have to fit onto pinch pleat hooks. What are your opinions on the wall sconces? I didn't even think about those! No plans to paint. It's just me doing the whole thing so for now I'm trying to keep it as simple as possible.
