This seems like a perfect shelf and cabinet layout based on our spacing. Could work nicely if face of fireplace were raw or white brick. Crown molding look? (not sure what to call fireplace surround) may be too formal but generally like.
This is the exact lay out of my formel living room with windows built in shelves on each side. I would never paint my brick or masonry but I love the tv over it, I dont have one at all in that room now.
