Exploration of the Renewal of the Aurora Area Based on Heterotopia Theory and Practice

This study is grounded in the learning and interpretation of heterotopic space theory, offering a comprehensive analysis of heterogeneous spaces in contemporary cities from both physical and social dimensions. The research focuses on outdoor urban environments, excluding typical heterotopias that are driven by singular functions. When addressing architectural spaces, particular attention is given to how building façades shape the adjacent streets and squares as part of the public realm. Through methods including literature review, case analysis, and field investigation, the study traces the conceptual development and analytical approaches of heterogeneous space, deepening the understanding of this theory through four interpretive lenses: "Space locality," "subjective presence," "nodes within the network," and "interactive online presence." On this theoretical basis, the research further proposes the application of heterogeneity as a design strategy to enhance urban diversity and distinctiveness. This includes specific spatial tactics such as “multi-pocket structures,” “layered juxtaposition,” and “networked formation,” which offer theory-informed and practice-oriented references for spatial development. Furthermore, the study takes the urban regeneration project in the Aurora district of Turin, Italy, as a key case, exploring how heterogeneous urban spaces and culturally distinct activities manifest in a context of multicultural interaction. By analyzing both the material morphology and the intangible life patterns of the area, a set of targeted spatial interventions is proposed. Within a holistic spatial framework of heterogeneous nodes, two representative sites—the “Cina Corner” and the “Vercelli Old Railway Segment”—are used to illustrate how point-based and linear nodes can be reconfigured through heterogeneous design strategies. The regeneration project consistently aligns with goals of enhancing local identity, stimulating economic vitality, and fostering social inclusiveness. A design framework of heterogeneity translation is constructed to identify embodied cultural interaction points and facilitate the collaborative transformation of multicultural elements within specific spatial frameworks. In addition to rearticulating cultural expressions, the design process also emphasizes relationships with local communities and the continuity of user activities, particularly those tied to Aurora’s prominent tradition of open-air street markets. The research thus aims to balance heterogeneity with coherence, while consciously avoiding the pitfalls of cultural relativism and hegemonic dominance. Given that the project remains a conceptual design study rather than a real-world implementation, certain limitations are acknowledged. Further in-depth cultural and social research is needed to substantiate the proposals. Nonetheless, this initial exploration into heterogeneity-enhancing spatial strategies as a response to cultural collision and coexistence aspires to provide a reference point for future discourse and practice on urban diversity, spatial distinctiveness, and the creation of resilient, vibrant living environments.
