In 2010, in its first significant expansion across the Schuylkill River, Penn purchased 23 acres at the northwest corner of 34th Street and Grays Ferry Avenue, the then site of DuPont Marshall Research Labs. In October of 2016, Penn completed the design (with help from architects Matthias Hollwich, Marc Kushner, and KSS Architects) and renovation of the center piece of the project, a former paint factory it named "Pennovation Works". "Pennovation Works" houses shared desks, wet labs, common areas, a “pitch bleacher,” and other attributes of a tech incubator. The rest of the site, which Penn is formally calling “South Bank” (of Schuylkill River), is a mixture of lightly-refurbished industrial buildings that serve as affordable and flexible workspaces and land for future development. Penn hopes that "South Bank will provide a place for academics, researchers, and entrepreneurs to establish their businesses in close proximity to each other to facilitate cross-pollination of their ideas, creativity, and innovation.
