I’d love any ideas for how to improve this long ugly wall in my row house living room. The two panels on either side of the center panel (with the vents at the top) are about 10 inches deep. It feels like it would be too busy to have a whole wall of shelves in one of them. Maybe wainscoting would help? Or painting? Or something more interesting to make the depressed sections less awkward and the air vents less ugly? Thank you for any ideas!
