A 3-seat sofa, coffee table and two armchairs in a "U" at the fireplace end. Art above the mantel, console tables with lamps flanking the FP. A drop leaf game table behind the sofa with straight chairs that match your dining set in the adjoining room. It can be expanded for additional dining or larger groups of gamers. Piano where benjesbride shows it with a couple of chairs angled either side of a round table and lamp in front of the window opposite. Window treatments, area rugs to ground both ends of the room.
You can go larger than this one, but just for concept as a sofa table/game table.
