The office building at 320 Park Avenue in Midtown Manhattan was originally completed in the early 1960s with a design by Emery Roth & Sons. In 1992, Mutual of America paid $130 million to buy the then-empty office tower from Olympia & York. Then, in 1994, the building was stripped down to its core and rebuilt, in a redevelopment effort spearheaded by Swanke Hayden Connell Architects. It was the best option for Mutual, as the building was constructed before the 1961 Zoning Resolution in NYC. This means that it was significantly larger than new buildings developed in the area, so Mutual would get to keep that extra office space if it just redeveloped the existing property. Nowadays, the building is home to various high-profile office and retail tenants, and continues to house the Mutual of America headquarters.

730 KSF of Class A Plaza District Office Space

The Mutual of America Building offers 730,000 square feet of Class A Plaza District office space across 35 stories. It is currently owned by Mutual of America Life Insurance Company, and managed by JLL. 

The LEED Gold-certified, International Style tower used to serve as the ITT Corporation World Headquarters, before the company moved out in 1990. In 1994, the building was extensively renovated, adding a new central building automation system, new HVAC, plumbing, electrical, fire and life safety systems. Amenities include a full-service concierge, a messenger center, generous amounts of natural light, and views of Park Avenue and Grand Central Terminal. Further features include tenant-controlled air conditioning and ventilation, 17 passenger elevators and 2 freight elevators, double-pane windows, and flexible floor plates.
