Symmetry defines this Art Deco living room: twin emerald velvet, channel-tufted sofas frame a round marble coffee table with a brass band and glossy black base. A black lacquer credenza with fluted detailing is crowned by a gold sunburst mirror and fan sculptures, while ribbed-glass sconces and a crystal-and-brass chandelier add sparkle. Cream paneled walls temper a bold black-and-white chevron marble floor, creating a luxe, graphic Deco statement.
