In this school-within-a-school complex, PreK-5 students and 6-8 students occupy distinct wings and share central core facilities, including administration, cafeteria, library, and 450-seat auditorium. Classrooms in each wing are placed along a gently curving corridor on the grassy Mystic River side of the structure. The elementary wing is more compact than the middle school wing, reinforcing the intimate school-within-a-school feeling; it includes music, computer, and science rooms specifically for the elementary school.

The middle school wing is based on groups of four classrooms and a central science room, with two teams per grade on each of three floors. Teacher planning and team offices, as well as specialized teaching spaces such as computers, technology, and language are located across the hall from team clusters.

An extensive playground, and ball fields (shared with a second middle school designed by HMFH as well) complete the 43-acre, riverfront site and serve the community when school is not in session.
