15 Union Square West is a residential building on East 15th Street overlooking Union Square in Manhattan, New York City. Originally Tiffany & Company’s 19th-century headquarters, it was refurbished and reopened in 2008 as high-end apartments. By 1952 it was owned by Amalgamated Bank. After a fatal accident where a pedestrian was struck by a falling piece of cast iron, they stripped the original façade and covered it with white brick. The building then stood unchanged for more than 50 years.
