The room is 20'-6" by 11'-4", so large enough to break into two areas -- the 15'-6" long wall and the approx. 5-ft door opening and short wall. TV could work on either of the 11'-4" walls, but more likely on the one with bookshelves. The sofa (or a different sofa) could then 'float', facing the 11'-4" wall, and leaving walking space on one side. A console table behind would be nice. Much like Beth H's second photo.
