Description

This exceptional three-bedroom, three-bathroom home at The Flatiron Building spans 3,054 square feet and presents a rare opportunity to inhabit a true architectural icon. Positioned on the 6th floor, this half-floor residence enjoys sun-filled south, east, and west exposures through beautifully scaled windows that embrace the building's historic form.

Expertly designed by Studio Sofield, the home blends dramatic architectural elements with an effortless sense of livability. A private elevator vestibule sets an intimate and refined tone on arrival, opening into a thoughtful floor plan that emphasizes flow, light, and privacy. Oversized, acoustically engineered windows bring natural light throughout the day, highlighting the residence's elegant detailing. The dramatic corner Great Room features over 10-foot ceilings and a signature custom curved window, creating a stunning architectural moment ideal for both entertaining and everyday living. The sleek Poliform kitchen is outfitted with metal-paneled cabinetry and a full suite of Gaggenau appliances.

The sunlit primary bedroom suite includes a curved corner window, a spacious windowed dressing room and separate dressing area with full-height Poliform wardrobes. The windowed primary bath is finely appointed with soaring ceilings, dual vanities, a Studio Sofield-designed soaking tub, generous walk-in shower, and a private water closet enclosed in nickel-framed fluted glass.

Two additional secondary bedrooms offer exceptional comfort for residents and guests, each paired with its own well-appointed en-suite bathroom featuring radiant heated floors.

Unique 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.
