In October 2019, Brookfield announced plans to rename the building 660 Fifth Avenue and begin $400 million of renovations in late 2020 after the remaining tenants' leases expired. Plans, designed by architecture firm Kohn Pedersen Fox, included eliminating many of the building's interior columns, offering double-high ceilings, adding four exterior terraces, and replacing the building's aluminum cladding with floor-to-ceiling windows.
