Middle School
Sidwell Friends School
Washington, District of Columbia
The Middle School renovation and addition transforms an awkwardly-sited, undersized, fifty-year-old facility into an exterior and interior teaching landscape. The Middle School project is seeking LEED(tm) Platinum certification as a demonstration of Sidwell Friends' commitment to environmental stewardship through high-performance building design and operations. The landscape and building will co-exist within, and demonstrate, a broader network of systems. Human systems - our inter-relationships with resources - are embodied by the landscape and building as natural systems. The system itself, rather than a representation, is the ethic rendered aesthetic.
