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.

Do you have room for a buffet? Those lights have been around for eons- old looking style so don't go that way. Have you considered a crystal chandelier? I'm thinking that based on your earlier inspiration photos. I'm getting ready to travel til mid Feb so I don't have time to help you shop but can try and give a little help while I pack. Have you looked at upholstered parsons chairs for your table? From the get go I always imagined your place with grays, white and blush. Are you a pink girl at all?

@ Rachel H We've created a layout for you with approximate dimensions from the pictures. So many options for colors that would work with those cushions and that rug! Warm tones of coral/ rust or even mustard would brighten up the room. Once you choose the colors on your chair you could add pillows that reflect those colors. You could place a couple of ottomans that can be moved around wherever required. As @My House says, you could add a slim console table and art/ Mirrours to the long wall by the door and create a nice looking entryway! We have made you another layout here. You can add or replace furniture and move them around to create your own layouts in interactive 3D designs here and also render your own photorealistic images here!

tv is on the wall in the area where the fan is, the long wall with no window. since you have a dining area in the kitchen I would treat the other area as part of the entry/ sitting area.
