 One of Vaughan's more ambitious landscapes is the 1986 Dr. Sun Yat-Sen Classical Chinese Garden in Vancouver, where he and architect Joe Wai took ten years to persuade three levels of government and private donors to fund the project, which cost $6.1 million.To help create an authentic Chinese garden, Vaughan enlisted the aid of 52 Chinese artisans.With the exception of the plants, all materials used to create the garden were imported from overseas.
