Constructed, 2005

Sited on one of the most prominent intersections in New York City, 505 Fifth Avenue houses 24,000 square meters of prime office space and 2,000 square meters of retail on a corner facing the New York Public Library and Bryant Park. Unlike most office towers in the city, where steel construction is the norm, 505 Fifth Avenue has a cast-in-place, reinforced-concrete structure that provides a level of building safety exceeding New York City Building Code requirements. The design, which uses a side-loaded core and concrete flat slab construction, allows for an uninterrupted, highly transparent glass skin and a finished ceiling height of 3.5 meters at the perimeter.
