William Pye's career as a sculptor spans over 40 years, working mainly in stainless steel and cast bronze, and since the 1980s water has become an integral and crucial element of a lot of his work.

He has exhibited in the USA, Hong Kong, Japan, Venice (Peggy Guggenheim Museum) and recently in Brazil. His work is found in public places, private gardens and corporate clients internationally. They include London Gatwick Airport, Hong Kong Airport, a major sculpture in the town square of Drammen near Oslo and a water sculpture for Wimbledon Lawn Tennis Club.

He is a Fellow of the Royal British Society of Sculptors and an Honorary Fellow of the Royal Institute of British Architects.
