Cozy seating for the family... the wall between the windows can have a large piece of art on it and drapes on windows in a lightweight fabric to soften the space would be great..what colors are you hoping to introduce into the room?...love the white shiplap and white credenza with sconces...great start..

The first thing that strikes me is that your curtain rod is too short which is why you have to push the curtains to the side which kills the vibe in this room. Get longer rods and linen-type curtains that are fairly similar to the wall color which will give the room warmth without looking busy. Please make sure that your area rug is as large as possible because that will make this room look fabulous. Little bitty rugs do not. I would choose an Oriental rug in warm colors because it will hide little accidents, at least until you can address them. I would definitely get a sofa, so great for cuddling with your husband and kids. I would place it in front of the window for good lighting for reading but also because it gives you the best sight lines into other areas of your home. Instead of a coffee table consider a large ottoman with a lid so that you have plenty of storage space. Please don't buy a brown or black leather couch. They look dated and are so difficult to decorate around. Try beige or caramel, with two chairs in contrasting colors, perhaps a nice blue or green, colors that will be in the carpet hopefully. You can also use the carpet colors to choose pillows for your soft furniture. Find some nice pictures to put on the walls, a large green plant, a bookcase or two (books are a must in a room) and side tables for lamps. By now your room will look gorgeous and be pretty well furnished and, most important of all, will be comfortable and fun to be in.

Can you return it and get a smaller one? (I admit I think your fireplace wall is lovely and I personally wouldn't ruin it with a television. But I am a tiny minority who has lived without television for almost 30 years.) Is there another room in which to put it, or do you prefer to use this room for watching it?

You have a black clock ? and the two art pieces; consider putting all three of them over the sofa in an informal grouping in the center.....clock on one half with the clock center going through the middle of the pictures one on top of the other with 2-3 inches between the pics. This would fill your wall. Like the suggestions for the fireplace mantle. Bring the sofa arms to where they are almost touching and put a large round type table in the new square place. Put the end tables on either end of the two sofas. Find some brass, silver, gold pair of big lamps for each end table...At least 27 - 29 inches tall, and fat to balance out your very large furniture. Find a pretty table runner in a bright pattern or turquoise, blue, green and put on your ottoman and secure the ends underneath so it fits tight and will add color and not fall off. Add basket for TV remote, etc. And I think an accent wall of paint in some shade of turquoise would warm up the room..... I have suggested turquoise because that is the color you have in the room, but everything is so neutral you could do any one color and add an accent color that works with the new color for more joy in the room.
