In the living room of this Beverly Hills home, interior designer Andrea Michaelson commissioned a brass frame by Gilad Ben-Artzi for the fireplace surround of Silver Wave marble from Stoneland USA. Above is a work by Amir Zaki flanked by a pair of Gentner lights. Coffee tables by Cassoni rest on a hand-knotted silk rug from Decorative Carpets by Stark. The oak plank flooring is from Tridentum.
