Waterline Square

The site was originally part of the Riverside South development and would be the last phase, known as Riverside Center.[5] Extell Development Company originally planned to build 2,500 residential and condo units, 140,000 square feet (13,000 m²) of retail and a cinema, a K-5 school for 750 students, a 250-room hotel, 3.2 acres of publicly accessible open space, and 1,500 parking spaces.[7] Despite public opposition, the plan was unanimously approved by the New York City Council in December 2010.[8]

The plan, which involved design by Christian de Portzamparc, were never realized and the company sold the land to GID for $676 million in 2015.[5][9]

In November 2016, GID received $1.243 billion in construction financing from a consortium of lenders including Wells Fargo, HSBC, JPMorgan Chase and the National Bank of Abu Dhabi.[10] The financing represented one of the largest construction loans ever in New York City and came at a time when financing for condominium projects had been difficult to obtain.

By November 2016, most of the site's foundations were complete.[10] As of April 2017, the buildings on the site began rising above street level.[11] The buildings topped out by the end of 2017.[12] In June 2017, Cipriani S.A. signed a 28,000 square feet (2,600 m²) lease, with plans to open a food market with several restaurants and stalls.[13]

Sales for the condominiums began in June 2017, with a projected sellout of $1.15 billion and an average price of $4.4 million.[14] The project was named New York City's fastest-selling condominium development in February 2018 by Architectural Digest, having sold 53 units worth over $200 million in just six months.[15] Applications for the affordable housing units opened in October 2018 and were available until December 2018.[16]

One Waterline Square contains 272 units, split between 56 condos and 216 rentals.[17] The interiors of the units were designed by Champalimaud Design in either white or natural finishes. The building's defining feature is a 12-story, sail-shaped facade extension above the building's entrance in the northeast corner.[21] The building's main facade is composed of clear reflective glass designed to interact with the Hudson River. However, the west facade is composed of gray brick to pay tribute to the historic brick-clad IRT Powerhouse adjacent to the building.[21] The same side of the building features a Porte-cochère entrance from West 59th Street for condominium owners.

The largest building, Two Waterline Square contains 160 condos and 216 rental apartments, totaling 646 units.[17] The interiors of the units were designed by Yabu Pushelberg. The building features several broken-up masses designed to minimize the impact of the large building.[22] The largest section of the building faces west towards the Hudson River to maximize views and light.

The smallest building, Three Waterline Square contains just 47 condos and 167 rentals for a total of 244 units.[17] The interiors of the units were designed by Groves & Co with marble and wood to reflect a contemporary theme. The building has a “netted” façade with uneven banding that provides texture.[23]
