An exclusive urban penthouse calls for a self-assured design, tailored to the exacting standards of its occupant. There’s a definite masculine energy to this living room, conveyed in the sober gray stripes of the wall treatment and the choice of luxurious black leather furniture. The overall effect could be slightly overbearing without thoughtful lighting choices. The elegant stainless steel bases of the standing and table lamps are in harmony with the room’s gentlemanly atmosphere, but there’s a deft lightness to their matching rounded glass shades.
