Description

Radiant with natural light, this exceptional four bedroom, four bathroom residence spans 3,828 square feet and occupies two coveted corners of the iconic Flatiron Building, offering south, east, and west exposures.

Thoughtfully designed by Studio Sofield for both grand entertaining and intimate living, the dramatic centerpiece of the home is its Great Room, measuring 58 feet by 21 feet with 10-foot ceilings, highlighted by a dramatic, custom-curved glass window that frames picturesque south- and west-facing views of cast-iron loft buildings that line the Fifth Avenue Ladies' Mile Historic District, a storied, landmarked corridor.

A private entry vestibule with direct elevator access sets a refined tone upon arrival, introducing the residence's gracious scale and thoughtful layout. Oversized, acoustically rated windows flood the home with sunlight throughout the day, enhancing the open flow and architectural elegance. The Poliform kitchen blends striking contemporary design with functionality, featuring sleek metal flush-panel cabinetry and state-of-the-art Gaggenau appliances.

The serene primary suite is a true retreat, featuring a signature custom-curved window with bright southeastern exposures, a spacious windowed walk-in closet, and a separate dressing area outfitted with floor-to-ceiling Poliform wardrobe closets. The windowed primary bath is beautifully appointed with high ceilings, separate vanities, a freestanding Studio Sofield-designed soaking tub, and a generous shower with a private water closet enclosed by nickel-framed fluted glass.

Three additional spacious bedrooms each offer en-suite bathrooms with radiant heated flooring, providing exceptional comfort and privacy for residents and guests alike.

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 residence represents a rare opportunity to own a sophisticated new condominium home within one of New York City's most celebrated architectural landmarks-where timeless design meets modern luxury in the heart of Fifth Avenue.

The Flatiron Building will feature 21st-century amenities designed and appointed by Studio Sofield, including a state-of-the-art wellness center 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 can 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. Occupancy this Fall.
