Hoping I can get some help - I have a 3 sided fireplace with step shelving above it (3 tiers - see pic). Looking for ideas on sprucing it up and making it a true focal point in the room. Right now it's just drywalled with the same color as the walls. Should I tile the sides and then add wood bottom that would overhang an inch or two? How do you think that would look? Any other ideas? Thanks much.
