The master plan for the Sidwell Friends School, a pre-K through 12th-grade Quaker independent school, focuses on meeting programmatic needs for its two campuses in Washington, D.C., and Bethesda, Maryland, including the unification of the campuses through coherent landscapes and enhanced pedestrian circulation. The renovation and addition to the middle school transforms a 55-year-old facility into a school that teaches environmental responsibility by example. The 39,000 ft2 addition more than doubled the size of the existing building, providing modern spaces for music and art, science and computer labs, counseling, and a library while retaining and enhancing the value of the existing structure. This project was chosen as an AIA Committee on the Environment Top Ten Green Project for 2007.
