The Flatiron Building, originally known as the Fuller Building, was completed in 1902 and instantly became one of New York City's most recognizable icons. Designed by Chicago architect Daniel Burnham in the Beaux-Arts style, its striking 22-story, wedge-shaped structure was engineered to fit the unusually triangular lot formed by the intersection of Broadway, Fifth Avenue, and 23rd Street. Its steel-frame construction was considered groundbreaking at the time, helping it soar to 307 feet, making it one of the city's tallest buildings. Nicknamed the "Flatiron" by locals for its resemblance to a household iron, the building's distinctive form anchored the neighborhood, eventually lending its name to the entire district and securing its legacy as an enduring symbol of Manhattan's architectural ambition. Now, more than a century after its completion, the Flatiron Building is entering a new chapter through a multi-million dollar conversion that will transform this storied office tower into 38 ultra-luxury condominiums, marking a profound adaptive reuse of one of the world's most famous structures to meet the demands of modern New York City living.
