Rooted in a participatory design framework, it explores how residents, in collaboration with designers and public stakeholders, can take an active role in transforming their living environments through vegetated interfaces. Here, the façade is reimagined as a thermodynamic system with multiple functions: climate regulation, air quality improvement, and the strengthening of the connection between city and nature. The project draws on the principles of regenerative urbanity — ecological restoration, positive life cycle, social inclusion, urban resilience, and co-evolution — to embed interventions within a systemic logic. It relies on transdisciplinary methodological tools (participatory workshops, sensory mapping, interactive devices) that foster the collective appropriation of greenery and the activation of a sustainable sense of togetherness. At the intersection of urban ecology, biophilic design, and spatial justice, this work redefines the façade not merely as an architectural element, but as a living, social, and environmental interface.}}
