WASHINGTON INTERNATIONAL SCHOOL GROUNDS
The Washington International School occupied 6 acres of a significant cultural and historic property designed by renowned architect Charles Platt and landscae architect Ellen Biddle Shipman, known as Tregaron, located in Cleveland Park. The property was divided in 1980 between the shool, which occupies the mansion and more formal grounds on the hilltop, and the Tregaron Conservancy, which owns the 20 acres of woodland and trails that surround the school. When the school expanded the building facility in 2006, the landscape was carefully designed to mitigate the views to and from the Mansion and South Lawn in order to preserve the historic nature of the estate. The design also integrated the approach from the formalgrounds of the school to the lower pond valley and trail.
