Nature can be regarded as one of the richest sources for understanding the processes through which form is generated, transformed, and organized. Natural structures are not merely collections of visual forms; rather, they are the outcomes of complex processes of formation, growth, organization, and adaptation to the environment. Studying these processes can move beyond formal imitation and provide a basis for understanding the underlying logic governing form generation and spatial organization in architecture. In this context, geometric patterns, proportions, repetition, hierarchy, self-similarity, gradual growth, and the organization of natural structures are among the fundamental principles that significantly influence the formation and performance of natural systems. The present study aims to identify the logic of form formation and organization in nature and elucidate its potential for developing biomimetic approaches in architecture. The research adopts a review-analytical methodology, drawing upon library research, specialized literature, and scientific articles related to biomimetic architecture, natural geometry, and form-generation processes in nature. The findings indicate that focusing on the underlying logic of natural structures, rather than directly imitating natural forms, can contribute to the development of new approaches to architectural form generation and organization. Principles such as growth and transformation, repetition and variability, hierarchy, self-organization, geometric relationships, and adaptation to environmental conditions have the potential to serve as conceptual and methodological foundations for the architectural design process. Accordingly, nature can be considered not merely a source of visual inspiration, but also a source for understanding the logic of form generation and spatial organization. Applying such principles can strengthen the relationship between form, function, and environment and contribute to the development of architectural approaches that are more adaptive, dynamic, and responsive to human and environmental needs.
