For more than a century, the Flatiron Building has stood as one of New York City’s most recognizable silhouettes. Long celebrated as a symbol of ambition, ingenuity, and architectural daring, the Fifth Avenue icon is now entering a new chapter as a private residential address for the first time in its 120 year history.
The debut listing, Residence 11 South, marks the building’s transition from commercial use to an exclusive collection of luxury homes and offers buyers a rare opportunity to live inside one of the city’s most enduring architectural landmarks. A Corner Residence Defined by Light and Scale
A Corner Residence Defined by Light and Scale
Priced at $16 million, Residence 11 South is a four bedroom, four bathroom home spanning 3,828 square feet. Occupying two coveted corners of the building, the residence is filled with natural light and framed by sweeping south, east, and west exposures.
At the heart of the home is a dramatic Great Room measuring 58 feet by 21 feet, defined by soaring 10 foot ceilings and a custom curved glass window that captures views over the Ladies’ Mile Historic District. The space balances architectural presence with everyday livability and is designed to accommodate both intimate moments and large scale entertaining.
Studio Sofield’s Vision for Contemporary Living
The interiors are conceived by Studio Sofield, led by renowned designer William Sofield. The design approach honors the building’s original character while introducing refined modern finishes throughout the residence.
A private entry vestibule with direct elevator access sets a composed tone upon arrival. Oversized, acoustically rated windows enhance the open flow of the home, while the Poliform kitchen pairs sleek flush panel cabinetry with state of the art Gaggenau appliances. Every material selection reflects a careful dialogue between heritage and contemporary design.
Private Suites and Thoughtful Details
The primary suite serves as a serene retreat, featuring a signature curved window, bright southeastern exposures, and a spacious walk in closet complemented by a separate dressing area. The en suite bath is appointed with dual vanities, a freestanding soaking tub, and a glass enclosed shower finished with nickel framed fluted glass.
Three additional bedrooms, each with its own en suite bathroom and radiant heated flooring, offer comfort and privacy for residents and guests alike. Throughout the home, an advanced Ketra lighting system by Lutron allows for fully adjustable light temperature and brightness, with optional circadian rhythm programming designed to support daily wellness.
Amenities Above Fifth Avenue
Residents of the Flatiron Building will enjoy a curated suite of amenities designed by Studio Sofield, including a wellness center with a 60 foot lap pool, cold plunge, sauna, and fitness facilities. Social spaces such as the Billiards Room and Piano Lounge overlook Madison Square Park and Fifth Avenue, while private storage and wine cellars are also available for purchase.
The building’s meticulous exterior restoration, overseen in collaboration with the New York City Landmarks Preservation Commission, preserves its Beaux Arts façade and ensures the next chapter remains rooted in craftsmanship and architectural integrity.
A Historic Address Reimagined
Originally completed in 1902 as the Fuller Building, the Flatiron was designed by architect Daniel Burnham and quickly became an emblem of New York City’s early skyscraper era. Now co developed by The Brodsky Organization and The Sorgente Group, the building is being thoughtfully transformed into 38 private residences.
With Residence 11 South now publicly listed, the Flatiron Building’s long anticipated residential debut is officially underway, offering a singular opportunity to own a home where history, design, and modern luxury converge.
