Working collaboratively with Skidmore, Owings and Merrill, Sasaki developed a master plan and provided landscape architectural services for the site and courtyards of the Upjohn executive office building. Offices are sited on a broad knoll overlooking the countryside. Pine tree groves define the limits of the site and screen views of the adjacent suburban houses. A reflecting pool defines the main entrance and a man-made pond—visible from the cafeteria and dining room—provides a drainage basin for the site. Informal groups of willows line the edge of the pond and pine and maple constitute the planting of the uplands.
