A leader in pediatric care since 1875, St. Christopher’s Hospital for Children’s nationally recognized programs and pediatric specialists provide exceptional care to children from throughout the Greater Philadelphia area and around the world. Their mission is to provide quality pediatric services in a caring, progressive environment. The new, 135,000 sf addition offers a new look to the campus. The main entrance is now through the tower, offering increased security and more efficient check-in processes. A unique aspect of the main lobby is the installation of a hot air balloon mosaic that is comprised of 180,000 individual marbles installed in a series of 200 pound panels. The floors are a neutral cream and gray and include origami in the shapes of boats, butterflies, and swans. These act as wayfinding elements as they lead patients and families to their destinations.
