Occupancy this Fall.

Positioned on the 18th floor at the iconic prow of The Flatiron Building, this extraordinary four-bedroom, four-and-a-half-bathroom residence spans 4,626 square feet and was masterfully designed by Studio Sofield. The home is anchored by a spectacular Great Room measuring over 63 feet by 27 feet, where historic arched windows frame sweeping skyline views over Madison Square Park, up Fifth Avenue and Broadway, and west to the Hudson River. From this unparalleled vantage point, the city unfolds in a striking panorama.

A private entry vestibule with hand-clipped marble mosaic flooring and a stone-trimmed portal provides direct elevator access and a gracious introduction to the residence. Nearly 11-foot ceilings enhance the sense of scale, while oversized historic arched windows, found on only two floors of the building, overlook picturesque park views and flood the interiors with natural light.

The windowed open kitchen is a refined expression of modern craftsmanship, featuring custom millwork by Poliform, sleek metal flush-panel cabinetry, and state-of-the-art appliances by Gaggenau.

Privately situated in the southeastern wing, the primary bedroom suite offers a tranquil retreat. Floor-to-ceiling Poliform wardrobes lead to an oversized, windowed walk-in closet. The primary bathroom is thoughtfully appointed with soaring ceilings, oversized arched windows, dual vanities, a freestanding soaking tub designed by Studio Sofield, and a shower with a private water closet enclosed behind 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.

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. 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.

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 sweeping 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.
