A campus landmark listed on the National Register of Historic Places, the Greek Theater is renowned for its open-air amphitheater and views of San Francisco Bay. The theater support facilities, including the box office and green rooms and seating access were upgraded in the late 1950’s by a team of designers that included landscape architect Lawrence Halprin. This new project continues these improvements with a new plaza that is the heart of an expanded concession and guest service facility. The plaza and concession building were designed to fit into the steeply sloped site and the existing stairway system. The project provides much-needed space to support the full range of events held at the theater. A simple palette of materials, including exposed aggregate concrete, Coast Live Oak and Olive trees, were selected to complement both the original theater as well as the 1950’s additions.
