Sustainable Urban Drainage Systems: Physical Modelling Analysis

The project presents an architectural and landscape model that explores how Sustainable Urban Drainage Systems (SuDS) can be integrated into the public realm to create a welcoming community space and enhance the environment. Instead of treating the drainage network as a technical requirement, the project shows how water can be an active part of the landscape experience. The design employs SuDS principles through planted rain gardens, permeable surfaces, tree planters, soft landscaping, and a blue-green roof. These features slow rainwater runoff into the sewer, reduce surface flooding during heavy rainfall, and enhance biodiversity and environmental performance. Alongside its drainage function, the landscape has been designed to encourage social interaction and well-being. Raised planters with integrated sitting benches and the pavilion create spaces for gathering, resting, and informal activities. Trees and planting provide shade, seasonal interest, and a connection to nature, while clear pedestrian routes improve accessibility and movement throughout the site.

The central landscape shows how SuDS can be part of the public realm, turning a functional requirement into an attractive feature. By incorporating water management, planting, and social spaces, the project supports a more resilient, sustainable urban design. The model has been produced using digital software and modelling in AutoCAD and Fusion 360, and in conjunction with laser-cutting and Bamboo 3D-printing techniques, using recycled PLA, such as wood PLA, Ashen concrete, and Marble, for textures and colours resembling the materials.
