15 Union Square West / ODA Architecture and Perkins Eastman Architects

© Robert Granoff

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.

The curtain wall of glass is offset from the outside surface of the cast iron facade creating an interstitial space between the apartments. The black zinc framed panels are double insulated, low E protection and low iron laminated glass having little refraction. This technology creates a near perfect reflection of the park during the day with gentle transparency at night cueing the historic structure while only hinting at the individual apartments located within. The design creates 7 new floors – a series of elegant glass cubes set at different angles to allow for vivid, unobstructed park and city views with spacious, private outdoor terraces.
