This research project takes the form of a creative, reflective and analytic investigation 'through theory and practice' into the role of the artist in enabling 'sustainable' urban environments. My initial focus on a spatial public art practice?s potential contribution to social sustainability should be understood as involving the capacity to contribute lasting benefits toward social well being whether of the individual or the community. My research later challenges the efficacy of this focus and argues for a more holistic approach to sustainability which addresses social, environmental, cultural and economic concerns simultaneously.
