Throop Plaza is a landscape court for the Knight Center and new Olin Business School at Washington University in St. Louis. Approximately a half acre in size, Throop Plaza is a multifunctional landscape meant to serve as a visually appealing space for people to pass through, congregate in, drive by and view from above.
The plaza is defined geometrically by a series of paths laid out to provide clear and focused direction to surrounding destinations. The area carved by these paths includes a tree grove, rain garden, native flowering hillside and an evergreen backdrop.
The raingarden and native flowering hillside along Throop Drive buffer the plaza from the street and visually reinforce the University’s commitment to sustainability. The tree grove is a sheltered gathering space that employs a mix of deciduous hardwood trees to create a mosaic of color and texture throughout the seasons. The evergreen hillside screens the garage and provides an all season backdrop that anchors the plaza.
