15 William, Residential skyscraper in Financial District, Manhattan, US
15 William is a 47-story residential tower in Manhattan's Financial District that rises 161 meters and contains 320 condominium units designed for modern urban living. The building includes a fitness center, heated saltwater pool, rooftop lounge, children's playground, and covered dog run for residents.
The site originally held the Corn Exchange Bank building in the early 1900s, followed by a 20-story office building that stood until the 1990s. The current residential structure completed in 2008 was the first ground-up residential project in the neighborhood and sparked broader residential development in the area.
The building represents a shift in the Financial District from a purely commercial area to a residential neighborhood where families and individuals now make their homes. This transformation has brought new energy, with local shops and restaurants emerging to serve the community.
The building features a public plaza area at street level that is accessible from William Street, making it easy to view the exterior and immediate surroundings. Best visited in the morning or early evening when foot traffic is lighter and you can better appreciate the architecture and open spaces.
The tower earned the playful nickname Post-It Note Building, a reference to its shape or design that has stuck among locals and visitors who appreciate the humor. Though recognized by Interior Design magazine in 2016 for its common areas, this distinction remains unknown to many who pass by daily.
