The lighted wood beams/mantle. We don't need as many and it could tie in exisiting wood color from other cabinets in room.
The tiles are similar to what we have in front of the living room fireplace. Then the wood could to flow over from the bookshelves that are on either side of the fireplace.
Very simple and would be similar but different to fireplace in living room.
Might jazz up area over the fireplace to do a simple tile design.
A simple idea like this might work.
Maybe stone with varied colors like these would bring out the other wood colors of the room.
Not sure if something like this would make it too dark in the room.
Same fireplace, different angle.
Check out how durably built gate is.
