apple_pie_order This fireplace has a dominant presence, but you also have some good sized windows or doors next to it. Would you take some bigger photos and show all four walls of the room, please? How wide is the rock ledge midway up? Does the light over the fireplace work?

collettec I know you have a stone ledge, and not sure how it's connected, but one possibility might be replacing that, if possible, with a more substantial and thicker mantel of wood that spans the width of the fireplace. Perhaps paint the adjoining walls a color closer to the fireplace color so not so dominant. Another possibility, use the ledge more as a shelf for vases or other objects.

Interiors International, Inc. A large architectural piece above the fireplace would give it dimension. Something like an old wood carving panel. Possibly a piece from the exterior of the outside of an old building. Go to your local architectural antiques store and start shopping. You will find something interesting I'm sure.

trhodus I attached images from the left and right sides of the room - opposite the fireplace is a small bar built in under the stairwell. I like the wood mantle idea - will look for something that may work. Thinking some window treatments on the fixed doors may help as well but not sure what to do there. The light above does work (once we replace the bulb:)). I appreciate your help!

Rachel Oliver Decorative Design A rustic mantel made of reclaimed wood would really help ground that whole area. Here are a couple of photos:

You also might think about a large, colorful piece of pottery. That will add some spice. And just to add one more thing, you might think about some neutral window treatments to play off the texture of that rock to soften it a bit. Quick-Fix Living Room

decoenthusiaste Suggest fabric romans on the windows.

houssaon I love you home. I think drapery panels hung as high as you can on decorative traverse rods in a lushious soft print fabic would soften the look of the fireplace. Not in this color, but a print like this: Living Room. Even this geometric pattern is nice: Georgian Revival - Family Room. Nice wall color and I like the sun screen, too.

If you can hang a classic landscape painting I think that would look good as well. See: T.A. Wolfson Design. No need for a mantle.
