Iconic triangular skyscraper in Manhattan. Designed by Daniel Burnham. Completed 1902. Originally Fuller Building, nicknamed “Flatiron” for resemblance to clothes iron. One of NYC’s most photographed buildings.
Architecture
Beaux-Arts steel-frame skyscraper. 22 stories, 285 feet tall. Triangular floorplan fits acute angle where Broadway crosses Fifth Avenue at 23rd Street. Only 6.5 feet wide at narrow north end.
Terracotta facade: Limestone and terracotta ornamentation. Italian Renaissance details. Rusticated three-story base, ornate cornice. Revolutionary at time—tallest building north of 14th Street (1902-1909).
Wind tunnel effect: Triangular shape creates downdrafts at street level. Urban legend: men loitered to watch women’s skirts blow up. Police coined term “23 skidoo” (telling gawkers to scram).
Historical Significance
Symbol of early 20th century optimism. Represented NYC’s vertical ambition. Skeptics called it “Burnham’s Folly,” predicted wind would topple it. Steel frame construction proved durability—survived 120+ years.
Photography icon: Edward Steichen’s “The Flatiron” (1904) established building as art subject. Alfred Stieglitz photographed it obsessively. Instagram era: daily tourist photos from Madison Square Park.
Cultural Impact
Spider-Man: Daily Bugle HQ exterior (Raimi trilogy). Superhero film landmark.
Designated landmarks: NYC Landmark (1966), National Historic Landmark (1989). Flatiron District named after building.
Recent Developments
$190 million sale (2023): Auctioned after ownership dispute. Buyers plan residential conversion (87 luxury condos). Empty since 2019—office tenants relocated during renovation planning.
Preservation battles: Landmarked exterior requires careful restoration. Facade deterioration (terracotta repairs). Interior conversion challenges: narrow floorplate, landmarked features.
