The Central Park Tower, Adrain Smith + Gordon Gill's 1,550-foot supertall tower in New York City, has topped out. 

The 131-floor, 179-unit complex, created for developer Extell, now reigns as the tallest residential building in the world, New York Yimby reports. Wrapped in rippled floor-to-ceiling blue-glass curtain walls, the tower is one of several new supertall structures currently under construction at the southern end of Central Park. 

Neighbors include KPF's 1,401-foot One Vanderbilt tower, the SHoP Architects-designed 1,066-foot 111 West 57th tower, and Jean Nouvel's 1,050-foot 53W53 tower. 

When completed, the Central Park Tower will include a triplex penthouse totaling more than 17,000-square-feet in size. The base of the building will be occupied by a 320,000-square-foot Nordstrom flagship store that will occupy seven levels. Floors eight through eighteen of the tower will house the building's residential amenities, including a 60-foot indoor lap pool, a screen rooming, a fitness center, a cigar room, and a 15,000-square-foot outdoor terrace situated on the 14th floor, New York Yimby reports. 

Construction on the tower is expected to continue into 2020.
