In an era of rapid urbanisation and climate challenges, understanding how urban land patterns contribute to resilience is crucial for sustainable development. This theoretical review introduces a novel framework positing that greater heterogeneity in plot sizes and land uses enhances urban resilience by promoting long-term preservation of built en-vironments, multifunctional spaces, and socio-cultural adaptability. Drawing on urban morphology, assemblage theory, and resilience science, we argue that fragmented ownership in small-plot fabrics acts as a barrier to large-scale redevelopment, fostering diversity that buffers against shocks. Through comparative case studies of Venice (Italy), Tokyo (Japan), Hong Kong, Mexico City (Mexico), and York (UK), we illustrate how historical small-plot subdivisions have endured centuries, supporting ecological, eco-nomic, and social resilience. The analysis reveals common patterns: ownership frag-mentation preserves fine-grained urban forms, enabling adaptive reuse (exaptation) and inclusivity. This paper addresses a gap in the literature by synthesising plot-level het-erogeneity with broader resilience outcomes, offering policy implications for protecting such fabrics amid global urbanisation pressures. Findings align with land system science, emphasising multifunctionality for regenerative urbanism.
