I am trying to figure out what to do with the spaces on either side of my fireplace. There will be a TV going above (there's no place else to put it!) but, I was thinking about built-ins and possibly windows on both sides because the room needs some natural light. For built-ins, I was thinking white cabinets on the bottom and then some shelving going up a few feet over the mantle. Any ideas re: size/shape of windows and/or built-ins would be appreciated! I'm having trouble visualizing! Thank you!
