In October 2007, Dover, Kohl & Partners and Chael Cooper & Associates conducted a charrette for the Master Plan of the Carrollton School. Students and staff of both campuses came together, rolled up their sleeves, and worked alongside the planning team to create a plan for the future of the school. Organized as a design charrette, the week was filled with a variety of events and meetings, organized to gain input and to review the progress of the plan as it was being created.

Following the charrette, the illustrative master plan and schematic architectural drawings were refined. Staff and students were asked to continue to provide input on the draft plan. In addition to ideas generated during the design session, visioning meetings were held frequently with school administrators to test new ideas and adapt the plan to the changing needs and expectations of the community.
