I'm trying to figure out how to furnish this living space in my new house. I have another space that will function as the formal living room, so this one's purpose is to be a family room/den for watching tv, playing video games, etc.

I can't figure out where I want to put a couch and where I'd put a TV. As you can see in the floor plan, there's only one wall with nothing on it. Clockwise from top: one wall has three bi-fold doors into a closet, the next has a large window, the next has nothing, and the last has a large window and a weirdly angled fireplace). I don't want to put a TV in front of any of the windows. Each of the walls has an outlet on it.

I don't have a couch for the space yet, so I also need to figure out what I want (sofa, sectional, chairs, etc).
