Place the sofa facing the fireplace. Place two chairs facing each other at either end of the sofa. You need an area rug like the one in the picture , about a 10x13 to groung the seating arrangement. I think the room will be too narrow to have the TV over the fireplace. Place the TV on a credenza to the left of the fireplace. Place a reading chair, floor lamp and small round table next to the bookcase, angled, facing the sofa.

Here is a like to a room similar to your room, without the nice big windows.

The idea is to arrange the furniture so that people walk around it, not through the conversation.

Do you have any pieces you want to use in the design?

Hi Kelsey,

This a great room with lots of light! My first suggestion would be to have two sofas facing one another with a coffee table in between. The sofa back facing the window should be off the wall either 36" or just enough for a skinny sofa table behind it where you can accessorize with lamps and decor. You want to keep minimum 36" of walking space around all sides of the sofas. I offer a couple of affordable design services including a floor plan service that maybe you'd be interested in getting some more one on one assistance. I'd be happy to help! www.hadijarowe.com/services 

We probably would've waited to mount the TV over the fireplace, and opt to mount it on one side of the fireplace over a console. We think you should be able to float a sofa facing the fireplace/TV and then have a chair on either side of the sofa. See our image below, except exclude one of the chairs. It might end up looking a little like this:

Beverly, the sofa dimensions are attached in the measurement image :) I believe 102x44 inches.
