It's the start of the fireplace. Imagine the TV above, at an angle that will provide an awesome view from every spot in the family room except the couch. I didn't realize the awkwardness until the framing went up. A new furniture layout may be needed. The wall behind the fireplace was ripped open to install a pocket door for my office. Until now, my office never had a door. Maybe I should order a lock for that door, too.
