Hello!

This living room is beautiful, but oddly pentagon shaped. I need help with how I should lay out the furniture and if I should take advantage of the dark gray recessed wall and utilize it as a bar, pictures/gallery, reading nook, or just a "separate" space from the living room. Where should the TV be and how should the furniture be arranged? The TV above the fireplace seems like a possibility, although an unpopular opinion. How should the wall to the left of the fireplace be used? Any input is greatly appreciated!
