Thanks for posting new views of your room. You are right, nothing can go in front of the paneling, and we won't block the built-in cubby. In that case let's work with the rest of the space. I found a picture on Houzz for your gallery wall. I think this will allow you to bring in color and texture and interest to your wall without taking up space like furniture would. Try to play with portraits and a couple of paintings in there too - mix it up. Otherwise I would not put anything at the top of that landing (I'd remove that console table). That picture wall should be enough visual interest to your space and it'll draw the eye to the furthest wall as you walk in your house. I would try a small piece with closed storage between the bottom steps and that door by the entry. It looks like the space is no wider than 26", so it'll be a challenge to find something that fits and is tall enough. I would not use the wooden piece you showed above because you want wider proportions and fairly narrow depth so you don't bump into it as you walk by. (something like this ) I would hang a mirror on top of primping. By the cubby you could add a single seat stool. I'm not particularly suggesting these colors for the stool and bombe chest but something along these shapes. At this point if you do that big picture wall and add these two pieces of furniture and a mirror, you might not need to hang anything on the wall above the cubby. Also, I noticed your chandelier is quite substantial for the space and hanging pretty low. Would raising it a little or replacing it by something a little smaller be an option?

Great space, love the room.. Have you ever considered painting the ceiling in a fun, vibrant color? Might be just the thing you need to brighten up the space. If you are in the market to look for new furniture pieces, be sure to check out www.bryght.com, they have stylish, modern pieces without the markup. Happy Decorating!

Is there something in the room you want reflected back that you love looking at? If not, why don't you find a nice piece of art work for the fireplace so you have something to enjoy rather than looking back at your other wall?

I feel it's too heavy looking for your room. You say it's a very large room, so you don't need it to make the room feel larger. Perhaps look for a picture/painting.
