At 390 Madison Avenue, an entire building is being reconceived from the inside out. In a remarkable feat of engineering, three million pounds of concrete and over 160,000 sq. ft. will be demolished in the building’s base to allow for the construction of entirely new floors at the top. Occupying the block front between 46th and 47th Streets, this newly renovated building will bring unprecedented facilities to a location unequalled in corporate Midtown. Building features include a a previous full renovation in 1989, a combination of interior package units and perimeter heat pumps allowing full-tenant control over its environment, with no overtime charges. Additionally, there's a separate building messenger center for deliveries, state-of-the-art building security with on-site parking garage for 150 cars and ample available basement space. The lobby and exterior have been completely rebuilt, and the entire building has all new high-capacity electrical, mechanical and security systems as well as state-of-the-art technology including fiber optics. The building is just steps away from the north entrance of Grand Central Terminal, The Roosevelt Hotel and the Rockefeller Center right in corporate Midtown, Manhattan.
