Description

Own a piece of Tiffany & Co.s storied history at 15 Union Square West.

15 Union Square West is a rare gem, with a history deeply embedded in New York Citys post-Civil War transformation. In 1870, Tiffany & Company chose this location for its first headquarters, commissioning a cast-iron building designed by John Kellum that The New York Times called a palace of jewels. For over three decades, Tiffany occupied this space, solidifying the areas commercial prominence. Today, the modern zinc-framed glass wall of 15 USW stands two feet in front of the original 1870 structure, preserving the buildings iconic facade and arched windows. This seamless fusion of history and contemporary design makes the building not only an architectural masterpiece but also the only condominium in Manhattan with direct views of Union Square Park.
