This participatory design invites users to co-create urban environments that support both birds and humans. Combining a tablet guide, a tactile building board with on-screen simulation, and a takeaway booklet, the project translates ecological complexity into accessible, hands-on interaction. Real-time feedback and playful storytelling help participants understand the impact of urban planning on biodiversity. Hosted in collaboration with the London Wildlife Trust, the project uses design as a tool for reflection, empathy, and meaningful action.
