This structure overlooking Union Square Park was originally designed for Tiffany & Company in the late 19th century. With careful consideration for upholding its historical place within the city, 15 Union Square West is gracefully translated into a 21st century residential masterwork. Creating harmony between the bygone and the present, the design for luxury living wraps the 12-story condominium residence in a translucent, layered glass skin, preserving the prominent cast iron arches of the original 5-story construction and dramatic 16’ceiling height.
