Located in the heart of Downtown at the intersection between Greenwich Village, Gramercy Park, and Flatiron, Union Square Park provides a backyard setting with 6.5 acres of green space and a weekly farmer's market. The bright, open great room is the heart of the residence, featuring soaring 17-foot double-height ceilings and iconic North-facing arched cast-iron window frames from the original Tiffany's building, now set behind a sleek glass facade. The expansive space accommodates oversized furniture, a 10-seat dining table, and a built-in dry bar with lit glassware cabinetry, making it perfect for living and entertaining. The kitchen seamlessly connects to the living area, sharing the same North-facing views and abundant natural light. It boasts an elongated Calacatta marble island, top-tier stainless steel appliances-including a Viking six-burner gas range, Sub-Zero refrigerator, and wine cooler-and sleek white cabinetry complemented by a stainless steel backsplash and contemporary lighting. A stainless steel and glass staircase leads to the private master suite, a spacious oasis with southern exposures, two oversized windows, two expansive closets, and room for additional furniture or a workstation. The en-suite bathroom features custom-designed finishes by Vicente Wolf, a double sink vanity, a wet room with dual shower heads, and a claw-foot soaking tub. The lower level offers two generous secondary bedrooms with en-suite bathrooms, custom closets, and southern exposures. A mahogany-paneled powder room on the main level conceals a laundry closet with a full-sized Miele washer and dryer. Additional storage includes a foyer closet and linen closets on the upper level. Other highlights include mahogany flooring, central HVAC, and an integrated Crestron system for shading, lighting, and climate control. A conversion of Tiffany & Company's 19th century headquarters, 15 Union Square West is a coveted high-end boutique condominium with hotel-like amenities including a 24-hour doorman, on-site concierge services, a zen spa with a 50' lap pool, oversized whirlpool, state-of-the-art fitness center with yoga studio and a recreation room. The premier location is in the heart of it all, near incredible cafes and restaurants, and the best of Fifth Avenue shopping. This is a co-listing with Compass/Corcoran.
