Perkins Eastman | 15 Union Square West

15 Union Square West

New York, New York
When designed in 1870 by architect John Kellum, 15 Union Square West served as the original building of luxury jeweler Tiffany & Company. The building utilized a cast-iron facade and elaborate decorative treatments befitting Tiffany and its products.

Brack Capital retained Perkins Eastman to convert the existing five-story, 93-foot-high building into luxury residential units, including the addition of seven more floors of penthouses on top of the existing structure. Because the original cast iron elements were removed in the 1950s, a new building skin was developed featuring an outer layer of thermal insulating glass and an inner decorative layer of a transparent material featuring a recreated image of the original Tiffany’s cast iron building.

This concept was carried through to the interior by reviving original finishes including black walnut, bronze, enameled metals, and cloisonné. The building includes a full suite of luxury amenities, including gym, swimming pool, spa, and suites of private wine cellars. Many apartments feature the original 18-foot ceilings with views to Union Square Park. All units will include private terraces to maximize views of the Square.
