Water hyacinth poses global challenges, impacting ecology, economies and communities. Its rapid growth in nutrient-rich waters disrupts ecosystems, navigation and recreation, as seen at Hartbeespoort Dam. Despite various management efforts, few have been effective. This dissertation proposes shifting from eradication to innovation by establishing a semi-permanent harvesting and processing facility at Hartbeespoort Dam. The facility will manage water hyacinth while creating economic opportunities for the local community. It will focus on processing hyacinth fibres into commercial bio-based products like natural biopolymers. By integrating harvesting, processing and production, the architectural intervention aims to address hyacinth proliferation sustainably. The outcome is a prototype facility dedicated to transforming invasive plants into valuable resources.
