The firm's landscape design for the Novartis Headquarters in Basel, Switzerland was one of eight projects worldwide to receive an "Honors Award" in the category of General Design.
PWP last year also won an Honors Award in the General Design for its landscape design for the National 9/11 Memorial in New York City.
The lead designer on both projects was Peter Walker.
This year's winners were announced Oct. 1, and the awards will be presented at the American Society of Landscape Architects annual meeting in Boston on Nov. 18.
The Novartis project, located at the company's century-old home on the Rhine River, was designed to clean up and transform a 51-acre toxics-laden site into an inviting composition of landscaping that "acts as canvases for endless types of activities, and is inviting throughout the entire year, changing moods with each season," according to a project description on the American Society of Landscape Architects website.
The awards jury said, "“The design is exquisite. It's simple and will become a landmark in time. It is an incredible project, very beautiful.”
The 2013 Professional Awards featured 33 winners selected from 534 entries in five categories. Each category included one "Award of Excellence" winner and several "Honors Awards."
