In its early days NYSID was located in various buildings on Madison Avenue and in Midtown—the last, an impressive site on East 56th Street, was designed by architect and faculty member William Breger. NYSID eventually settled into its current location on East 70th Street in 1994, among the city's top fine art and antique dealers and renowned museums. A major expansion and renovation—to NYSID's tandem building on East 69th Street—followed in the late 1990s. And, in 2010, the College opened its LEED-Platinum Graduate Center on Park Avenue South and 28th Street, which houses faculty, staff and more than 150 graduate students.
