PCS is located at 100 Bunn Drive on a seven-acre campus in Princeton Township. The main entrance is off Bunn Drive, just north of Princeton Shopping Center. The K-4 classroom building was reconstructed on the foundation of the New Jersey Bankers Association building that the school purchased in 2001. The light-filled classrooms are bright and spacious, helping to make learning fun for the students.
The main, three-story school building which houses grades 5-8 was renovated in stages from 1997 to 1999. The school is particularly proud of the modern, fully equipped science laboratory, made possible by a generous grant from the Challenge Foundation.
The new campus center, completed in 2010, has classrooms for art and music, a black-box theater, and a gymnasium. The spacious center gallery hosts gatherings and art shows.
The campus also includes playing fields, a running path, and playgrounds.
