Construction Tour: 425 Park Avenue
425 Park Avenue rising in Midtown.
Construction has wrapped up 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. Though the tower has been open for months, the tower had its official grand opening ceremony last week. One of the tower’s main tenants, Citadel, has leased 415,400 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 Jean-Georges Vongerichten.
The exterior wall is composed of unitized curtain wall vision panels, textured stainless steel column cladding and solid corrugated panels at the elevator and services core at the east facade.
