Reimagining informality: Lessons from Naples on growth, adaptability, and the value of incompleteness in urban planning

This paper explores the interplay between structured urban planning and the unpredictability of informality in urban development. At its core, it examines how cities, exemplified by Naples, evolve through informal, superfetative processes that stem from a grassroots level, contributing to their adaptability, resilience, and vibrancy. By challenging conventional planning paradigms, superfetation embodies a collective urban creativity that redefines urban landscapes in response to changing community needs and environmental conditions. The discourse is framed within the theoretical context of systems theory and biological paradigms, advocating for a planning methodology that can embrace flexibility and adaptability. This approach reflects the principles of autopoiesis in biology, where systems are self-creating and continuously evolving. The paper argues that cities can be interpreted as Complex Adaptive Systems (CAS), where informality plays a crucial role in fostering a symbiotic relationship between urban environments and their inhabitants’ individual experiences, needs, and creative solutions. The paper presents case studies from Naples, specifically focusing on the practices of superfetation within this complex and rich urban settings. These examples demonstrate how informal architectural practices, while often at odds with legal frameworks, provide essential contributions to the city’s architectural and social fabric. The study suggests that such practices should not only be tolerated but actively integrated into the planning paradigm to enhance urban resilience and adaptability. In conclusion, the paper calls for a re-evaluation of urban governance and planning regulations to acknowledge and incorporate the value of informal processes. It proposes a shift towards more inclusive planning frameworks that accommodate the fluidity of urban life and recognize the contributions of all citizens to the urban design process. This approach would not only enhance the vitality of cities but also ensure they are better equipped to respond to future challenges. The insights gained underscore the need for further research into the integration of informal practices within formal planning to maintain their essence and vitality in urban development.
