Brookfield Office Properties has started construction of the first phase of the $4.5bn development project in Manhattan, US, which will be built on a platform over railroad tracks.
The five million ft² Manhattan West development will include two office towers with two million ft² of space, a residential tower and 1.5 acres of public space.
Phase one of the project, located on the western side of Pennsylvania Station, will feature a $680m platform in the Hudson Yards district, which will be home to Manhattan West.
The five-acre site will span the area along Ninth Avenue and Dyer Avenue, from West 31st to West 33rd streets, across from the future Moynihan Station transit hub.
The first phase of the project also includes installation of a 120,000ft² platform over the railroad tracks that lead to Pennsylvania Station.
The platform will be made up of a series of 16 bridges over the active rail yard and is anticipated to be completed in 2014.
New York Mayor Michael Bloomberg said, "The state-of-the-art Manhattan West development will include two new office towers, a residential tower, new shops and restaurants, and an acre and a half of new outdoor space, making it a vital piece of the mixed-use community we’ve envisioned for the Hudson Yards area, and which is now starting to take shape."
Brookfield is currently in talks with a number of potential tenants in the technology, media, entertainment, professional and financial services sectors for the office tower.
Brookfield said it will start office tower construction when an anchor tenant is chosen and Cushman & Wakefield is acting as the leasing agent for Manhattan West.
Skidmore, Owings & Merrill is the master plan architect, working in partnership with SLCE Architects on the residential portion.
Designed by High Line firm Field Operations, the outdoor public space at Manhattan West will be home to an arts and events programme, similar to the programme at Brookfield Place New York/the World Financial Center.
Brookfield secured a $340m loan to finance construction of Manhattan West development.
