The history of architectural and urban practices reflects humanity's enduring quest to comprehend and shape its environment, often through the lens of unifying meta-narratives. This paper critiques the tendency to seek cohesive frameworks, drawing from Graham Harman's speculative realism and Bruno Latour's “Principle of Irreduction,” which challenge hierarchical structures in understanding reality. These perspectives underscore the irreducibility and multiplicity of existence, advocating for a paradigm shift that resists determinism and embraces open-endedness. In this context, Adrian Bejan's constructal law offers a compelling alternative for interpreting architectural and urban forms. Constructal theory conceptualizes form and design as evolutionary responses to flow systems, framing architecture as an active participant in the dynamic interplay of environmental, social, and temporal forces. This perspective encourages a reevaluation of architectural practices not as definitive solutions but as iterative processes that engage with complexity and contingency. By integrating constructal theory with contemporary philosophical critiques, this article proposes a poly-narrative of architecture and urbanism that aligns with the fluidity and multiplicity of modern existence. It argues for a departure from static frameworks toward adaptive methodologies that acknowledge the interconnectedness of actors, scales, and temporalities. Ultimately, this approach reframes design as a dialogic process, fostering resilience and innovation in confronting the uncertainties of a rapidly evolving world.
