Harborside Financial Center Plaza 3

Harborside Plaza 3 offers a bright and contemporary interior with large, flexible floorplates. Units feature a variety of configurations, and have complete access to all the amenities and features of Harborside Financial Center, including retail, restaurants, a full-service Hyatt Regency hotel, and attractive outdoor areas.

Harborside Plaza 3, along with Harborside Plazas 1 and 2, is an outstanding example of adaptive re-use. Originally built in 1929 for the Pennsylvania Railroad, it was converted to class A office space in 1982. Purchased in 1996, Mack-Cali Realty Corporation then took it back down to its core and shell and replaced it with the most modern building systems and infrastructure. The Company has since completed many upgrades and renovations, in addition to developing three additional class A properties on the site.
