Living with antiaues shouldn’t feel like living in a museum-just ask Patrick McGrath. “The challenge and fun is displaving them in a way that feels contemporary,” the designer reflects. That was the impetus for his new by-appointment gallery: an airy space (also his office) on the seventh floor of Manhattan’s Cable Building. Here. a freshly stained George lll table might mingle with Roman statuary and a set of Biedermeier chairs recovered in black linen. Elsewhere. an Art Deco daybed cozies up to a chinese altar table and a venetian capriccio. McGrath likens such juxtapositions to alchemy.
