Today Extell Development got the green light from City Council to build Riverside Center on one of the last major parcels of land at the edge of the Upper West Side. Among several concessions made to the community, the developer agreed to sink $17.5 million into Riverside Park, build a 100,000 square foot school, renovate a recreation center on West 59th Street and build 500 affordable housing units (though much of it offsite).
The 3.1 million square foot project includes a series of towers designed by Christian de Portzamparc between 59th and 61st streets and will provide as much open space as Lincoln Center, the architect told AN last year. Portzamparc worked with landscape designer Signe Nielsen to break up an existing superblock and create a view corridor that extends toward the Riverside Park. Like most mixed-use projects, the developer said public amenities, such as grocery stores and the school, would fill the base of the towers.
