15 William, Residential skyscraper in Financial District, Manhattan, US
15 William is a 47-story residential tower in the Financial District of Manhattan, standing at 528 feet (161 meters) with 320 condominium units. Residents have access to shared amenities such as a fitness center, a heated saltwater pool, a rooftop lounge, a children's play area, and a covered dog run.
The site once held a bank building from the early 1900s, which was later replaced by an office building that remained standing until the 1990s. The current tower, completed in 2008, was the first ground-up residential project in this part of the Financial District and helped open the neighborhood to further housing development.
The Financial District around this building has shifted over time from a place where people only worked to one where they also live. Cafés, grocery stores, and small restaurants have opened nearby to serve residents who now fill the streets at hours when the area used to be empty.
The building sits on William Street and is within walking distance of several subway stations in the area. The exterior is best viewed from across the street or from a short distance, as the entrance and ground-level areas are reserved for residents.
The building has earned the nickname Post-It Note Building among locals, a reference to its shape that many passersby have never heard. Its shared interior spaces were recognized by Interior Design magazine in 2016, which is uncommon for a purely residential tower.
