Description

Occupancy this Fall. Positioned on the 19th floor at the iconic prow of The Flatiron Building, this exceptional four-bedroom, four-and-a-half-bathroom residence encompasses 4,575 square feet and was masterfully conceived by Studio Sofield. At the heart of the home is a spectacular Great Room measuring more than 63 feet by 27 feet, where windows frame sweeping skyline vistas across Madison Square Park, along Fifth Avenue and Broadway, and west toward the Hudson River. A private entry vestibule, finished with hand-clipped marble mosaic flooring and a stone-trimmed portal, offers direct elevator access and an elegant arrival to the residence. Soaring 12-foot ceilings amplify the impressive sense of scale, while oversized windows overlook the park and bathe the interiors in natural light. The windowed open kitchen is a sophisticated showcase of contemporary craftsmanship, featuring custom millwork by Poliform, streamlined metal flush-panel cabinetry, and state-of-the-art Gaggenau appliances. Privately positioned in the southeastern wing, the primary bedroom suite is a serene and secluded retreat. Floor-to-ceiling Poliform wardrobes lead into an expansive, windowed walk-in closet. The Primary Bathroom is beautifully appointed with soaring ceilings, oversized windows, dual vanities, a freestanding soaking tub designed by Studio Sofield, and a spacious shower, with a private water closet enclosed by nickel-framed fluted glass. Additional bedrooms are generously scaled, and each features its own en-suite bath with radiant heated floors, completing this exceptional offering. A discreet service entrance opens to a separate utility room equipped with two sets of full-size washers and dryers, millwork, and a sink, enhancing both functionality and privacy. Unprecedented in new development and thoughtfully integrated throughout each residence is the Ketra ultra-premium lighting system by Lutron, providing fully adjustable light temperature and brightness, along with optional circadian rhythm programming for optimal comfort and wellness. This exceptional residence represents a singular offering within one of New York City's most celebrated architectural landmarks. The Flatiron Building will feature 21st-century amenities designed and appointed by Studio Sofield, including a state-of-the-art wellness center exquisitely conceived with an oversized fitness center and dedicated areas for private training, strength and cardio workouts, a sports simulator and lounge, a 60-foot lap pool, and a cold plunge with adjacent sauna for thermal contrast therapy. Residents may also enjoy views of Madison Square Park and Fifth Avenue from the mezzanine-level Billiards Room and Piano Lounge. Private storage and wine cellars are available for purchase.
