What is that structure underneath the curtains? Is it possible to have floor-length curtains in a color similar to the wall, although honestly that color doesn't do the room any favors. I would paint it the same color as the other wall, which will make the room look larger and more cohesive. . To make this room look comfortable at all you need an area rug or two. You need a coffee table and some side tables with table lamps because the lighting you have is terribly harsh and cold. Those chairs are not attractive, I'm sorry to say, but you can at least find some nice, colorful pillows to spiff them up. The black couch is puzzling too; it doesn't go with anything. Try pillows in nice colors there too. I just went back and read that you're happy to change the furniture, Yes, please! I would not pick leather, and would choose lighter colors, preferably fabric. That wall and ceiling lighting has to go; it will make everyone look horrible and hurt your eyes. You need less bulky pieces of furniture. Try turning the couch toward the TV because I think you can see it from there, assuming there is enough room to get around the couch. This is a really awkward space. You definitely need pictures on the wall to brighten this room and area rugs, as mentioned.

We think to the left of the fireplace should work. Just place sofa facing the fireplace/TV setup, and float the sofa in the room, and then you can have two chairs facing the window (s). See our setup below? You can do it like this:

Great, thanks! I would use a round table that can extend to oval when you have company in the dining area, right over near the kitchen. One chair backing into the corner, rather than a chair with its back to the kitchen door. The desk can stay right where you have it in this photo. Sofa on the wall with the windows with a side table at each end. Two chairs across from it with a table between them. I sketched a pic but can't post comments on my phone, boo :(

I like Manon's layout the best. In your current layout (where you just moved the furniture), pull that chair out of the corner and closer to the sofa so that people have to walk AROUND the seating area instead of THROUGH it. Please do not buy one of those combo TV console/fireplaces. They are truly an abomination. It you want a fireplace, install an electric or ventless one on the wall, add a mantel shelf that's longer than the TV and mount the TV on an articulating arm. If you don't do a fireplace, mount the TV anyway so you can turn it to watch from the sofa.
