Apartment 30 (8B) presents an exceptional layout distinguished by scale, balance, and architectural poise-qualities seldom achieved in contemporary construction. This elegant three-bedroom, three-and-a-half-bath residence is defined by grand proportions, soaring ceilings, and dramatic floor-to-ceiling windows that frame unobstructed, cinematic views of Union Square Park. Positioned on the tranquil eighth floor, the home enjoys remarkable privacy and minimal ambient noise, benefiting from the Square’s distinctive traffic pattern.
The living and entertaining spaces are both refined and inviting, centered around a gas-burning fireplace that lends warmth and intimacy. The custom-designed kitchen serves as a striking focal point, featuring a marble-topped island with stainless steel and mahogany detailing-an ideal setting for both formal entertaining and everyday living.
Each generously proportioned bedroom offers impressive ceiling heights, abundant closet space, and luxurious en-suite baths appointed with travertine marble, porcelain Xilo tile, and oak vanities topped in Corian. A gracious powder room and a fully equipped laundry room further enhance the residence’s thoughtful functionality.
Residents enjoy access to an extraordinary collection of amenities, newly renovated, including a 50-foot lap pool, cold plunge, whirlpool, private cabanas, an expansive fitness center, yoga studio, massage room, saunas, and hot tubs. White-glove service is paramount, with a 24-hour doorman.
15 Union Square West occupies a singular place in New York’s architectural and commercial history. In 1870, Tiffany & Co. selected this address for its first headquarters, commissioning a cast-iron edifice by architect John Kellum-hailed by The New York Times as “a palace of jewels.” For more than three decades, Tiffany’s presence anchored Union Square’s commercial ascendancy. Today, a striking zinc-framed glass facade stands just forward of the original 1870 structure, preserving its iconic arched windows and historic character. The result is a masterful dialogue between heritage and modernity-culminating in what remains the only condominium in Manhattan with direct park frontage on Union Square Park.
