The Potomac School in McLean, VA is co-ed K-12 private school for over 1,000 students situated on a 90-acre campus within a natural setting that includes forest, streams and fields. In 1999, cox graae + spack architects was commissioned to undertake a comprehensive campus master planning effort intended to become a resource for evaluating the need for facility improvement and campus growth, provide a vehicle for matching construction opportunities with available funding and serve as a basis for creating capital campaigns in conjunction with specific plans for addressing Mission goals and capital budget guidelines. In 2004 and 2008 the master plan was updated through a design partnership with Sasaki Associates. Implementation of the master plan began with the renovation of / addition to the Upper School (grades 9-12). The mission was to create an environmentally sensitive 21st century school building that extends teaching spaces from the classroom to the outdoors. The Upper School project included the renovation of its existing building and the construction of two new wings, the East Building and the Tundra Building. The Potomac School’s new Lower School (K-3) was the second phase of this plan. The School’s mission to teach environmental stewardship begins with the youngest students, and the School’s goals are supported by the campus architecture. The Lower School project took advantage of bucolic rolling hills on the northwest side of the campus. The Intermediate School (grades 6 - 8) project was completed in 2013, and is the sixth project that cox graae + spack architects has designed on the campus. The Intermediate School received an addition totaling 8,712 sf to house six classrooms, a new main office, three breakout areas for students, new bathrooms and a two-story commons.
