We are about to purchase a remodel house in Northen Mississippi. The fireplace is a large brick wall that divides the breakfast room and living room. For some reason the builder and original owners installed the fireplace only on the breakfast room side, which leaves a giant ugly brick wall facing the living room. Is it possible to open the fireplace up to the living room side? So that both rooms could enjoy the flames? Will doing this create massive air drafts and energy leaks? Plase help!
