Designated a National Historic Landmark and listed on the National Register of Historic Places, Columbia University’s Pupin Hall provided the backdrop for a new space that inspires the future of the school’s physics department and honors its history at the same time. Perkins Eastman’s design for the Center for Theoretical Physics reimagined the building’s eighth and ninth floors into a destination for distinguished researchers, visitors, and students. With open views extending across campus, a distinct central stair links the center’s two floors as well as a variety of informal gathering areas, flexible lounge, café space, and individual offices. Designed with the express intent to increase face-to-face interactions, the space fosters an environment conducive to spontaneous collaboration among scientists and students. Hands-on educational tools throughout each floor and a refreshed lounge honoring Nobel laureate Isidor Rabi set the tone for the department’s environment.
