The Thames Barrier region formerly known as Prince Regent's Wharf has an industrial history stretching back over one hundred and thirty years. Industry ranging from petroleum distillation to timber treatment has contributed to the environmental concerns associated with this site. While a few hot spots were off-hauled, the bulk of the materials were simply rearranged to reflect the vision of the design team. This profile was then capped with crushed concrete and a geotextile layer and topped off with imported clean soil to confirm the site's suitability for use. The Thames Barrier Park is a prime example of how materials of environmental concern can not only be recycled, they can form aesthetic features crucial to the design of a project.
