Tallest Building in the US: One World Trade Center
One World Trade Center in New York City is the tallest building in the US, with a structural height of 1,776 feet and 104 usable floors above ground. The tower is owned by the Port Authority of New York and New Jersey and serves as a primary office hub for multiple tenants, including financial firms and government agencies. Its height intentionally references the year of US Declaration of Independence, and the building opened in 2014 after years of design and construction changes. For current leasing and tenant details, see the official Port Authority page on the World Trade Center.
The building is ranked as the tallest in the United States by standard architectural height measurements, which include spires but exclude antennas. It is also listed among the tallest buildings in North America and globally on several real estate and engineering databases. The tower features redundant safety systems, high-performance concrete, and a reinforced concrete core designed to meet modern skyscraper standards. Its position as the tallest building in the US is based on publicly available height data from the Council on Tall Buildings and Urban Habitat.
Height, Design, and Key Facts
One World Trade Center reaches 1,776 feet to its architectural top, making it the tallest building in the US by standard height criteria. The design emphasizes energy efficiency, with rainwater collection systems, natural ventilation strategies, and low-emissivity glass to reduce solar heat gain. The tower includes approximately 2.6 million square feet of office and retail space across multiple floors, with the uppermost levels featuring a public observation deck and broadcast facilities.
The structural system relies on a reinforced concrete core and perimeter columns that support both gravity and lateral loads, including wind forces typical of the New York City skyline. The building is classified as a supertall skyscraper and is frequently cited in rankings of the tallest buildings in the world.
