Learning
The School District of Philadelphia (SDP) is dedicated to delivering equitable, high-quality education in modern, supportive learning environments. Serving over 200,000 students citywide, the district continues to upgrade its facilities to meet the evolving needs of students, teachers, and families—recognizing that effective learning depends not only on technology and design, but also on well-managed acoustics.
The original Lewis C. Cassidy Elementary School, a century-old structure in West Philadelphia’s Overbrook neighborhood, presented significant challenges.
Outdated classrooms, limited technological infrastructure, and inadequate building systems hindered the school’s ability to provide a next-generation learning experience. To better serve the community, SDP set out to replace the aging building with a forward-thinking facility designed for academic excellence, sustainability, and neighborhood engagement.
Partnering with SDP, EwingCole designed the new Lewis C. Cassidy Academic Plus School, an 83,000-square-foot K–8 facility serving 570 students. Central to its success is the integration of acoustic performance. Through acoustic textured wall panels and acoustic ceiling baffle systems, the school effectively controls sound to enhance speech clarity, focus, and comfort. The result is a fully realized environment where both the design and the educational experience are complete.
Design is an iterative and interactive process
that works best when ideas are measured,
discussed, and challenged.
