In 2024, downtown Manhattan welcomed another towering marvel to its skyline: JPMorgan Chase’s new headquarters at 270 Park Avenue. This monumental structure occupies an entire city block, bordered by Park Avenue to the east, Madison Avenue to the west, East 47th Street to the south, and East 48th Street to the north. Rising 60 stories high, the $3 billion, 2.5 million-square-foot building will house up to 15,000 employees, making it not only one of the city’s most impressive architectural feats but also a beacon of sustainability and innovation. Park 270 is set to be the tallest building in New York City entirely powered by hydroelectric energy.

As the first major development under the 2017 Midtown East rezoning plan – designed to incentivize taller commercial projects in the area – this new structure reflects the city’s evolving skyline. “This building is a testament to our long-term investment in New York City, and it will continue to impact future generations of New Yorkers,” said Jamie Dimon, JPMorgan Chase Chairman and CEO. “I am incredibly proud of the exceptional team that has worked tirelessly through challenging conditions to bring this vision to life.”

A standout feature of the project is its use of hot-dip galvanized steel. On the upper floors, exposed to intense heat and moisture from the building’s electrical components, this galvanized steel will ensure the structure can withstand the corrosive environment for decades to come. Roughly 1,500 tons of steel was hot-dip galvanized on this super structure, fabricated in Banker Steel Company’s plants across Virginia, New Jersey, and Orlando. Hot-dip galvanizing was chosen for its unmatched corrosion resistance and longevity, minimizing the need for preventative maintenance and ensuring the building’s steel frame will endure for generations.
