Pfizer Headquarters Office-to-Apartment Conversion

under construction

Conversion of two office buildings in midtown Manhattan, New York, including the former Pfizer headquarters, into about 1,600 apartments by adding more than a dozen stories atop the older structure and redesigning and expanding the other. The project involves complex engineering challenges such as ensuring older buildings can safely support new loads and adapting office floors for residential use. A recent incident involved buckling of steel columns on the 21st floor of the newer building, leading to temporary work stoppage and investigation.
