Located in the suburb of Port Melbourne, Fishermans Bend has been known for the light industry since colonial times and is changing towards a centre for innovation in advanced manufacturing, engineering, and design. The site was purchased by the government and has the potential to pilot the transformation. To resolve the fragmented ownership, poor public transport, and environmental challenges, this project proposes a "green-blue-brown" framework: combining the interconnected green spaces, stormwater management, and brownfield restoration. Firstly, through a top-down method, use GIS to identify areas with potential ecological significance for development into green spaces. Then from bottom to top, various approaches are proposed for different parcels based on their characteristics, to suit human activity demands and stimulate community interaction. Finally, an urban park is designed as an example that stitches the property edges to maximize the ecological and cultural value of the entire system.
