320 Park Avenue
320 Park Avenue was originally designed by Emery Roth & Sons in 1960 and is now the headquarters to one of largest mutual life insurance companies.
In 1995, a Swanke Hayden Connell-led redesign expanded the 35-story tower’s square footage to 730,000 square feet. Over ten years ago Platinum craftsmen restored the marble finishes throughout the main floor building lobby and continue to maintain the lobby floors on a nightly basis with a permanently assigned staff.
