Description

Occupancy this Fall. This combination is subject to a pending amendment to the Offering Plan. Encompassing over 7,600 square feet of interior living space, this extraordinary full-floor residence at The Flatiron Building presents an exceptionally rare opportunity to own two seamlessly combined residences, creating an entire floor within one of New York City's most celebrated architectural landmarks. Perched above Madison Square Park on the 17th floor, the home enjoys sweeping views of the park and the Midtown skyline, with abundant natural light streaming through beautifully proportioned windows that showcase the building's iconic geometry and historic character. Thoughtfully designed by Studio Sofield, the residence pairs timeless architectural elegance with effortless modern livability. Private elevator landings create an immediate sense of arrival, opening to a gracious floor plan distinguished by exceptional scale, seamless flow, and remarkable privacy. The dramatic corner Great Rooms serve as the centerpieces of the residence, offering expansive dimensions, impressive ceiling heights, and signature curved windows that perfectly frame the surrounding city skyline. The windowed Poliform kitchen is equally refined, featuring sleek metal-flush cabinetry with concealed hardware and a full suite of Gaggenau's latest state-of-the-art appliances, combining sophisticated design with exceptional performance. The primary suites are envisioned as a tranquil private sanctuary, complete with generous living quarters, dressing areas outfitted with full-height Poliform wardrobes, and two beautifully appointed, windowed primary baths. The spa-inspired primary bathrooms include dual vanities, custom Studio Sofield soaking tubs, oversized walk-in showers, and private water closets enclosed in nickel-framed fluted glass, all enhanced by dramatic ceiling heights. Additional bedrooms and private living spaces are thoughtfully arranged to provide outstanding comfort and flexibility, each complemented by en-suite bathrooms featuring radiant heated floors for an elevated everyday experience. Setting the residence apart from virtually every new development, the home is fully integrated with Lutron's premium Ketra lighting system, allowing residents to customize both light intensity and color temperature while offering optional circadian rhythm programming designed to support wellness and everyday comfort. This exceptional residence represents a rare opportunity to own a newly created full-floor condominium home within one of New York City's most iconic architectural treasures, where historic significance, contemporary technology, and extraordinary scale come together overlooking Madison Square Park. Residents of The Flatiron Building will enjoy an exclusive collection of Studio Sofield-designed amenities, including a state-of-the-art wellness center with an expansive fitness facility, private training studio, dedicated strength and cardio spaces, a sports simulator and lounge, a 60-foot lap pool, and a cold plunge with an adjoining sauna for thermal contrast therapy. The mezzanine-level Billiards Room and Piano Lounge overlook Madison Square Park and Fifth Avenue, while private storage rooms and wine cellars are available for purchase.
