Bill Simon Field House Principia School

St. Louis, Missouri
Construction Cost: $28.4
Area / Square Feet: 86,934
Occupancy Date: February 2023

Athletics and team-building are core components to the student experience at Principia School, and its facilities needed to match the expectations of the institution, students and families. The old facility lacked sufficient gym space, causing significant scheduling challenges. Other athletics spaces were constrained, as well. 

The performance gym within the new structure serves as a competitive space for basketball, volleyball and P.E. classes. With retractable bleachers providing flexible seating for 700 spectators, as well as direct access to the viewing platform above, the gym also hosts special events, guest speakers, educational programs and camps for the entire school. 

The three-court gym allows for multiple sports — including track and field, basketball, volleyball, pickleball, badminton and baseball — to practice simultaneously. Additionally, the adjacent fitness center is equipped with cardio machines, free weights and a turf strip for functional training. A versatile multipurpose space has been incorporated into the facility to accommodate wrestling, dance, cheerleading and special events. 

The new building also features a Character Lab classroom, integrating wellness and character education, aligning with the school’s mission of character development and holistic growth. 

To facilitate student-coach interactions, the locker rooms serve as individual character labs, named after the school’s esteemed coaches and equipped with marker boards and video monitors. 

The offices are designed to encourage effective communication and provide a welcoming environment for visitors, promoting inclusivity within the school community. Gender equity was prioritized in the design, as well. The new facility provides gender-diverse spaces, including locker rooms and restrooms, ensuring a comfortable and inclusive environment for all users.
