The Visitor Center is a remarkable synthesis of architecture and landscape design, replacing a modest gate on Washington Avenue with an enticing entry into the 52-acre garden and housing interpretive exhibits and a room for orienting tour groups; a dramatic, leaf-shaped event space; an expanded store offering garden-related products and plants; and other visitor amenities. Conceived as a seamless extension of the Garden’s landscape, the sinuous glass building is embedded in an existing hillside at the Garden’s northeast corner. Composed of two linked forms that seem to appear, disappear, and change shape as the visitor moves through and around them, the building offers a new sequence of views into and through the Garden. In addition, the Visitor Center incorporates numerous environmentally sustainable features—most notably a 10,000-square-foot living roof—that are aimed toward earning LEED Gold certification.
