Manhattan West is a 7-million-square-foot (650,000 m2) mixed-use development by Brookfield Properties, built as part of the Hudson Yards Redevelopment. The project spans 8 acres and features four office towers, one boutique hotel, one residential building, 225,000 square feet (20,900 m2) of retail space and a 2.5-acre public plaza. The project was built on a platform over Penn Station storage tracks along Ninth Avenue between 32nd and 33rd Streets.

Hudson Yards is a neighborhood on the West Side of Midtown Manhattan in New York City, bounded roughly by 30th Street in the south, 41st Street in the north, the West Side Highway in the west, and Eighth Avenue in the east. The area is the site of a large-scale redevelopment program that is being planned, funded, and constructed under a set of agreements among the State of New York, City of New York, and Metropolitan Transportation Authority (MTA), with the aim of expanding the Midtown Manhattan business district westward to the Hudson River. The program includes a major rezoning of the Far West Side, an extension of the New York City Subway's 7 and <7>​ trains to a new subway station at 34th Street and 11th Avenue, a renovation and expansion of the Javits Center, and a financing plan to fund the various components. The various components are being planned by New York City Department of City Planning and New York City Economic Development Corporation.
