The new research tower for Children’s Hospital of Philadelphia is the first step in creating a unique, identifiable South campus that expands biomedical research, clinical research, ambulatory care, office and support facilities. Having participated in the South campus planning process, Ballinger implemented the Master Plan’s research initiative - the design of 1,000,000 SF of basic research and biomedical research, supported by a 275,000 SF vivarium. Planned for 29 stories in two phases, the new building occupies a prominent urban site across from the Main Campus. Behind the glass facade lies a carefully woven configuration of spaces that provide flexibility, functionality and clarity to the research environment. The building’s intriguing dichotomy of glass curtain wall and terra cotta cladding projects an image worthy of the nation’s #1 Children’s Hospital. The solid terra cotta form acts as an anchor for the building and houses the building’s laboratory core, its primary function. The core is wrapped by three distinct layers of glass curtain wall, representing the secondary functions of the building, each differing in design and complexity.
