About the Building

900 Third Avenue is a 36-story, Class A office tower located between East 54th and East 55th Streets in Manhattan’s Midtown East and Plaza District. Completed in 1983, the approximately 600,000-square-foot property was designed by Cesar Pelli, Viñoly Design Architects, and Emery Roth & Sons. Its distinctive reflective glass façade, prominent Third Avenue entrance, and efficient office layouts make it an established corporate address for financial services firms, law practices, investment companies, and other professional tenants.

The building offers flexible office configurations, with floor plates ranging from approximately 4,000 to 18,000 square feet. Its rectangular layouts accommodate a variety of workplace designs, including open workstations, perimeter private offices, conference rooms, executive suites, and collaborative areas. Generous windows provide natural light throughout the office floors, while upper-level spaces benefit from expansive views across Midtown Manhattan.
