Construction Tour: 425 Park Avenue
425 Park Avenue rising in Midtown.
Construction is nearing completion at 425 Park Avenue, L&L Holding Company's 897 foot tall office tower rising on Park Avenue in the Midtown East neighborhood. L&L has partnered with its co-equity partner and co-developer Tokyu Land Corporation and co-managing partner BentallGreenOak, with design by internationally acclaimed architects Foster + Partners. The 47-story tower replaces a 30-story tower formerly on site, keeping approximately 25% of the previous structure to allow for more height. As of this week, the tower has received its Temporary Certificate of Occupancy (TCO) from the New York City Department of Buildings (DOB), which signals substantial completion of the project. L&L has turned over 16 office floors to the anchor tenant Citadel Enterprises LLC for tenant fit-out. Citadel has pre-leased 331,800 square feet of the tower’s total 670,000 square feet, which includes one of the three-story diagrid floors and the penthouse office floor.
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.
