Led by landscape architects Dan Kiley and Peter Ker Walker, the firm was engaged in a wide range of master planning, resort design, and landscape projects at both residential and civic scales. The two partners had been working together since 1962 and were two-thirds of the firm Kiley Tyndall Walker until Ian Tyndall embarked on his own private practice in 1979. Demonstrating their presence on both coasts, Kiley Walker worked on urban development projects in New York and Seattle, among other cities. The nine-story atrium they designed for London’s Standard Charter Bank allowed the firm to experiment with vegetation and water features in an interior environment. In the U.S. their designs for both the Dallas Museum of Art and the nearby Fountain Place expanded on these elements to create successful public spaces. For the museum, geometric clusters of trees combine with water walls to create secluded spaces within a larger sculpture garden. At Fountain Place, the firm developed a network of walkways interwoven with fountains and a grid of bald cypresses that creates a cool gathering place in downtown Dallas. NationsBank Plaza (now the Kiley Garden) in Tampa, Florida, also utilized formal geometry to provide a link between the landscape and its corresponding building. Throughout their association, Kiley Walker collaborated with pioneering architects such as I.M. Pei, Skidmore, Owings and Merrill, and Edward Larrabee Barnes. In 1986 Walker started his own practice in Burlington, Vermont, while Kiley continued his work as the Office of Dan Kiley.
