Description

Residence 5A at 15 Union Square West is a spectacular two-bedroom, two-and-a-half-bathroom loft defined by soaring 15-foot ceilings, original grand cast-iron arched windows, and sweeping views of Union Square Park and Greenwich Village. Set within the iconic landmark conversion of Tiffany & Company's 19th-century headquarters, this rare downtown residence pairs historic architectural character with sophisticated modern luxury.

The expansive open living and dining space is designed for both everyday living and effortless entertaining, with an abundance of natural light and dramatic scale. At the center of the home, a chef's kitchen features an elongated Calacatta marble island, custom lighting, and top-of-the-line appliances, including a built-in Miele espresso machine, Sub-Zero refrigerator, Viking six-burner range, wine fridge, and garbage disposal.

The serene primary suite offers two oversized closets and charming Soho-style views. Its spa-inspired en-suite bathroom is outfitted with a luxurious wet room, clawfoot tub, shower, and dual sinks, creating a true retreat within the city.

A spacious second bedroom features its own elegant en-suite bathroom, offering privacy and comfort for guests.
Additional highlights include a dedicated laundry room, stylish half bathroom, mahogany flooring, central HVAC, and an integrated Crestron system for lighting, shading, and climate control.

15 Union Square West
offers an exceptional collection of five-star amenities, including a state-of-the-art gym, full-length lap pool, hot tub, sauna, spa, and treatment rooms. Concierge and dedicated building staff provide the level of white-glove service expected of a truly luxury residence.

Enjoy immediate access to the Union Square Greenmarket, Michelin-rated restaurants, fantastic shops, and major subway lines including the N, Q, R, W, 4, 5, and 6.
A rare combination of scale, history, luxury, and location, 15 Union Square West 5A offers an extraordinary downtown Manhattan loft lifestyle.

Leased for $25,000/month through April 2027.
