In April 2025, residents of Manhattan's tallest residential tower walked into court with a 46-page complaint and a number that stopped engineers cold. Ten inches. The depth of a crack reported inside the structural spine of the most expensive condominium ever built in New York City. The 165 million dollar lawsuit alleges 1,893 documented defects. A trash chute that sounds like a bomb going off inside the building. An elevator that trapped a resident for 1 hour and 25 minutes on Halloween night. A facade waterproofed with the same silicone used to protect yachts. And a lead developer who was foreclosed on by his own co-developer inside his own building. 432 Park Avenue, the building Harry Macklowe called the building of the 21st century, has now become Billionaires' Row's most expensive cautionary tale.

432 Park Avenue at 56th Street and Park, Manhattan — 96 stories, 1,396 feet tall, a height-to-width ratio of 15 to 1 that made it the most slender super tall building ever constructed anywhere in the world when it topped out in 2014. Designed by celebrated architect Rafael Vinoly. Engineered by WSP Cantor Seinuk, the firm that helped invent the modern super tall. Built with white Portland cement, 70,000 cubic yards of concrete, and 12,500 tons of rebar. The lower 38 stories poured at 14,000 PSI concrete strong enough to hold up a small mountain. Five open mechanical floors cut into the tower every 12 stories to break up vortex shedding. Two 660-ton tuned mass dampers between floors 86 and 89 designed to swing in opposition and cancel out wind oscillation. At the center of it all, a 30-foot square reinforced concrete spine with walls 30 inches thick — the element that absolutely cannot be compromised on a building this slender. The first sales closed in 2015 and 2016. By 2015, ninety percent of the units had sold for over 2 billion dollars. The penthouse went to Saudi retail billionaire Fawaz Alhokair for $87.7 million. Thomas Peterffy of Interactive Brokers took the 84th floor. Jennifer Lopez and Alex Rodriguez moved in by 2018. Total project sellout reached $3.1 billion. The developers cleared a reported $900 million in profit. Then November 2017 — catastrophic flooding between floors 83 and 86. November 2018 — pipe failures on floors 60 and 74, two of four elevator shafts flooded, $9.7 million in water damage in a single year, insurance premiums up 300 percent. October 31st 2019 — a resident trapped in a wind-stalled elevator for 1 hour and 25 minutes. June 2021 — the second electrical explosion in three years. September 2021 — the first lawsuit, $125 million sought, language calling the situation "one of the worst examples of sponsor malfeasance in the development of a luxury condominium in the history of New York City." August 2023 — CIM Group forecloses on Macklowe's three personal units inside the building. March 2023 — architect Rafael Vinoly dies before the worst comes out in court. April 2025 — the second lawsuit. 46 pages. 1,893 defects. 73 percent of mechanical, electrical, and plumbing systems allegedly not built to specification.
