I was thinking something along the lines of this... You can use the colors of the rug, like the terracotta, in your pillows on the chairs. It's too bad you don't have room for the alternative placement of the TV, and in that case I would get a console to put catty-corner on the walls next to the fireplace on the right, even though the windows will be behind the TV. Since you say this is not your permanent home perhaps that will do as a stopgap measure. The couch should be facing the fireplace, unless you want to angle everything to face the TV. The chairs will go perpendicular to the couch. The fireplace nook you can fill with a painting or perhaps an arrangement of blue and white Chinese porcelain (have a look at etsy). With a beautiful rug I'd suggest a glass and metal coffee table so the rug design shows through. You'd also need side tables but I see no way that you can have lamps without trailing cords. Find a way to display books on the tables, which give a lived-in look. Pardon me if I use pictures of my home to illustrate some of these points; your taste may be quite different, but it's just to give you some ideas. This rug is made of polypropylene and therefore much more affordable, but you can see how these colors would brighten your room and give you colors for pillows on your couch and chairs. You can find rugs on e-bay, overstock.com, pottery barn, just google area rugs and then indicate "traditional" or "oriental" and you'll find lots of ideas.

A 55" TV is only about 48" wide. I really think the sofa should go on the wall and the TV should go above the fireplace. Otherwise, you have to choose between awkward TV viewing or an awkward sofa location. eta: I just read that you never use the fireplace. You could put the TV on a console in front of the fireplace (gasp) I know. But I think you could make it work if none of the fireplace was visible.

Hey guys! so I wasnt intentionally not replying...my phone got stolen from a department store (I accedentally set it down, lol!) So I got a new phone and had forgotten my login info (I was automatically logged in) I have still been searching for inspiration. I shouldnt be, but I am still so embarrassed of my house. A lot of it is because due to indecisiveness I have not replaced the furniture I cant stand. I feel like the things I pin on pinterest or save to the ideabooks still just dont fit my living room. I feel like because of the rectangleness of the room the dining room and living room almost have to match/coordinate. It also has to match the floors and the taupe wall color since those arent going anywhere anytime soon. In the ideal world I like shiny dark furniture, especially a dining table but in my head those are all diffrent dining rooms, or open dining rooms that match the kitchen. When you walk in its BAM living and dining room. So I feel like it's just making due with the space. I'm just not really a big fan of my house layout in general, but I am embarrassed to have people over.. My husband absolutely does not want to spend a lot of money on it. We were in a place to, but when we could I couldnt make up my mind. I found this on an Instagram bloggers. Her house really resembles ours, the couch against the window wall, the open living and dining room. I like how her coffee table and dining table match each other, it looks very coordinated. And I also like the black coffee table top with the black on her TV (in the same place as ours). But she posts links to her furniture and I def cant afford that or I'd just be copying lol! I wish I could just copy someone by the book but these bloggers all have a diffrent budget than I do! Hers does have a bit of a farmhouse vibe, but I like it because it is modern. I also like the dining table because it is not cloth chairs and with kids that doesnt always end the best! The style though farmhouse is very popular right now and modernized, from what I can tell. I like walking into target and seeing the target style. I know its modern and popular. I just want to make sure the dining room matches the living room. But I'm in a play or safe kind of vibe. Rooms to go and ashley is more in our budget, cheaper furniture sets and financing options. I like the ones at world market, wayfair etc. but they can be pricey and no financing.. This is that bloggers page:

Do you have plans for the niches next to the fireplace? Maybe builtin storage cabinets and TV on a pull-out swivel on the right. The L side you could leave blank or have shelves above the lower cabinet. It will add some architectural interest and allow for storage. Then a seating area in front of fireplace - sofa and 1-2 chairs. A small desk area in the space between sofa area and dining. Though I’d probably have a computer station that closes off (do you need for desk top or just lap tops?)
