15 Union Square West, Nueva York

15 Union Square West is located on the edge of Union Square in Manhattan. It is a boutique condominium that marries historic character with modern luxury. Originally built in 1870 as the headquarters for Tiffany & Co., the building was fully renovated in 2008: restoring the cast-iron arches of the original façade and adding new floors above, yielding a 12-story building with 36 residences. The units offer a variety of layouts, featuring lofty ceilings, large arched windows, and interior designs blending contemporary finishes with historic elements. Kitchens include stainless steel appliances, large islands, and open layouts; master baths use stone or high-end materials and are spaciously appointed. Upper units boast views over Union Square Park. The building provides 24/7 concierge / doorman service, and premium amenities such as a full spa with lap pool, fitness center, yoga/Pilates studio, and media room. Its location is superb — walking distance to the Union Square subway hub (multiple lines), with dense commercial, cultural, and dining options nearby.
