Standing just to the north of the iconic XYZ Buildings in , 1271 Avenue of the Americas, aka the Time-Life Building, is currently undergoing a major transformation of its exterior curtain wall, outdoor plaza, landmarked lobby space, and mechanical makeup of the elevators and MEP systems. Built in 1958, Rockefeller Group Development Corporation is bringing the building into the twenty-first century by bringing on Pei Cobb Freed Partners Architects LLP to helm the refurbishment of the 48-story office tower, which stands 587 feet to its rooftop.
