Funded by the voter-approved half-penny sales tax, Duval County Public Schools (DCPS) has engaged in a program to replace and revitalize school facilities throughout the District. RDB Design Associates (RDB) and Cooper Carusi Collins Architects (CCCA) were contracted by DCPS to design a new K-5 prototype school based on a modified reuse of an existing prototype. The District wanted a 21st Century design that will promote student engagement and incorporate a cross-discipline approach to teaching. This resulted in the design of shared areas within the building which support a variety of individual and group learning opportunities. The design consists of a one-story structure which includes the secured entry lobby, administration, multi-purpose cafeteria/ auditorium, kitchen, and group restrooms. The one-story structure is separated by a fire wall from the classroom wings. Held-open doors located at the fire wall may be closed for secured after hours use of the multi-purpose spaces for school and community events. The classrooms and collaborative learning spaces are located within the 2-story structure. The ground floor has the Media Center, Maker Space, Science Lab, Technology Lab and Art Room which are connected with movable glass walls for maximum flexibility. The classrooms are organized in a 2-story “horseshoe” configuration creating secure outdoor learning areas as well as social gathering spaces. Based on the developed Southside Estates design prototype, DCPS has awarded RDB two additional schools: Spring Park K-5 and Louis S. Sheffield K-5 Elementary Schools.
