I like the Woodstove being set back into the previous fireplace. We Might b e able to add some stone atop our existing heath and do something like this. Charnwood Island oak fireplace beam, brick rear wall and reclaimed Yorkshire stone hearth.
Slip a new mantle over the old one: Fireplace update. Create a mantle that slips over the top of the existing brick and anchors to the wall on either side! I'm going to have somewhere to hang stockings this year! Now I need stockings.
