Property Description
This exceptional designer residence at 15 Union Square West offers the best of NYC living with dramatic ceiling heights, stunning arched windows, and complete serenity across two levels. 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. 18 square feet of on-site private resident storage included. 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. Please contact us to schedule a viewing.
