About the Building:

320 park avenue office space guide
Named after current owners, Mutual of America Life Insurance, 320 Park Avenue in the Plaza District was originally designed by Emery Roth & Sons. Completed in 1960, it later underwent a complete rebuild in 1994 after sitting empty for 2-years following Mutual of America’s purchase. Under the keen eye of Swanke Hayden Connell Architects, the building was stripped down to its core in 1992 to ensure it would stand up to the 1961 Zoning Resolution in NYC. As a result, it stands tall compared to other buildings in the area, offering more office space through redevelopment. 

However, where tenants really see the building’s worth is in the $35 million refurbishment designed to meet the heightened expectations for higher end, unique amenities post the pandemic’s work from home office model. Over 25,000 square feet of interior and exterior amenities are more than enough to lure people back to work, including a completely redone lobby and café, a building gym, and a private 16th floor exclusive restaurant with a stunning terrace boasting spectacular views of Park Avenue.

Moments from the landmark MetLife Building and bustling Grand Central Terminal, it remains the headquarters of Mutual of America, with modern high-speed elevators reaching the upper levels in minutes and a full-service concierge catering to your every need. Other high-profile jobs completed by Swanke Hayden Connell include the Statue of Liberty, Trump Tower, The Continental Center and One Seaport Plaza so tenants know they are in good company.

Onsite dining includes Chipotle Mexican Grill, Little Beet, and Just Salads, with endless choices just a few minutes away at the Grand Central Market. If you’re in the mood for steak and drinks, Benjamin Steakhouse is an excellent option, and nearby shopping includes Sephora, H&M, Banana Republic, and T-Mobile. Of course, you can always pop into the Newport Center. Proximity to the Grand Central Terminal makes transportation a breeze for city dwellers and commuters alike.
