Construction Tour: 425 Park Avenue

Southwest corner from Park Avenue.

Facade installation is underway at 425 Park Avenue, L&L Holding Company's 47-story office tower rising on Park Avenue in the Midtown East neighborhood. Designed by Foster + Partners, the tower replaces a 30-story tower formerly on site, keeping approximately 25% of the previous structure to allow for more height. The massing strategy calls for three distinct volumes separated by triple height setbacks with diagrid structure. While the first setback at floor 12 will be leased as office space, the Club Level at the second setback on floor 26 will offer to all tenants a wellness center and food service by Chef Daniel Humm and restaurateur Will Guidara. Superstructure has currently reached the second triple height seback at floor 26, surpassing the halfway mark.

The tower facade, currently being installed at the lower third volume, is composed of unitized curtain wall vision panels, textured stainless steel column cladding and solid panels at the elevator and services core at the east facade.
