The Flatiron Building is the highest-yield Manhattan adaptive-reuse story of 2026 — Daniel Burnham's 1902 Beaux-Arts skyscraper currently undergoing residential condominium conversion.
The case for it starts with the Burnham / Beaux-Arts architectural pedigree — "one of NYC's most iconic Beaux-Arts skyscrapers," carrying NYC Landmark (1966) and National Historic Landmark (1989) designations. Inside, the William Sofield interior design "draws inspiration from materials uncovered during the restoration — historic railings, original ironwork, and marble mosaics — while integrating modern luxury finishes." Most decisive of all is the tapering site geometry, which yields "dramatically elongated great rooms, angled sightlines, and a spatial experience that simply cannot be replicated in a conventional tower."
Recent transactional context: Floor 21 (full-floor) in contract at $58.5 million. As of early 2026, "nine of its 38 apartments into contract" per public reporting.
