I like your idea of shelves next to your TV and cabinet. You might check out Ikea if you have one near you. Their Expedit shelving units come in various sizes and look great. You can insert a few woven baskets that Ikea has which fit into the shelves if you have things that would look cluttery otherwise or to contain smaller things. The units can also be stacked so they can be almost floor to ceiling. We recently did this in a study/guest room. We have 9 ft ceilings so we put 2 stacked narrow expedit units on either side of a day bed, and we were happy with the effect. You can also find good deals on bookshelves on craigslist, and you might be able to find a pair there. What else do you have in the room? On your other walls, you could put large photos/art work/maps etc that you find appealing. If you take a picture and upload it, you might get even more specific help here.

I ordered the canvas art and hopefully receive it next week and then decide what colors to pull from it for the chair cushions and placemats. I think I like your ideas about maybe not putting anything on the other walls for awhile and see if the canvas is enough. What kind of centerpiece do you think???I was thinking maybe some sort of vase.

Ah, so you do have another space for lounging/TV watching. If you're pretty much sure you'd rather have a TV here too-I'd be satisfied with a (say) credenza or something to host a smaller size TV, which you can surround with some shelving with books, or maybe art..you can bring in plants-a lot of them..lots of interest since some of them grow like crazy and are virtually indestructible..)) and they always look at home-any style, any room you take, you can't go wrong with introducing plants, Remember Clifford Simak's purple flowers? lol you can paint the walls..you can wallpaper them if you're brave..you can put a mural on-there are some amazing ones. there are many many ways to make this room interesting. also don't forget-you look at it now while it's empty. but when you'll actually live there-you'll have furniture, fabrics, books..now it's a blank slate but it won't stay this way. it will be you and your family plus this room. it will be interesting enough without the feature wall. which you still can decide to do-I continue to think these wood planks are way cool..but they might be too overwhelming..and I would think very carefully about how to incorporate them, and whether it's worth investing in. That's personal of course and you might find that yes, you really want it, TV or no TV. Then I'd introduce more of that wood around..maybe wooden frames on art? maybe woven shades in the window? maybe painting the mantle another color so it'll blend more with the walls? And I'd use this plank wall more heavily then if I decide to put it in..it's a big space, and it might be useful and very very cool to have more on it than just the TV. Whatever you decide-it's exciting. Lots of possibilities here. And yes you're right..you don't need to match the wood finishes. You do need to consider how they will look together..in rare instances mixing just doesn't work. Say red mahogany or similar very expensive woods..)) find it hard to incorporate lol. Passed on amazing nightstands several years ago..the most useful amazing high quality nightstands I ever saw(on Craigslist)) but they just didn't blend in, what can I say.. But I don't think that's your case.

Shelving on either side of the t v would look nice and fill the wall. Move some of the wall art onto the shelves. Also, center the sofa to that wall and move the chair to the left of sofa.
