The courtyard garden was designed with the help of the dutchman Piet Oudolf who is in the vanguard of the 'New Perennial' planting movement, a movement which strives for a more naturalistic look in gardens by using carefully selected, rather wild-looking, perennials and placing an emphasis on grasses.

Piet is now renowned worldwide and, among his many projects, has designed parks for in both central Chicago and downtown Manhattan.
