Seven decades after designing Lever House, SOM returns to the iconic modernist building to resume its restoration, continuing its long-lasting stewardship of the project. SOM previously revisited the building in 2001, restoring its façade using high-performance materials while preserving the original architectural image. This time, the intervention concerns the ground floor and the third level terrace, as well as the mechanical systems, to significantly improve the building’s energy performance. When complete in 2023, the renovation will become an important example of extending the life of the midcentury built environment.
