Modern architecture in the 21st century has entered a critical phase in which it can no longer adequately respond to complex environmental crises—such as climate change, rapid loss of biodiversity, and the fragmentation of urban ecosystems—through improvements in energy performance alone. Cities function as devices that concentrate and redistribute flows of material, energy, and information within a large-scale ecological system. Within this macroscopic flow, individual buildings should no longer be understood as fixed objects, but rather as organic organizations that continuously interact with and are reconstituted by their environments. Until now, sustainable architecture has traditionally mitigated environmental burdens through technology-driven efficiency improvements, but this has mainly remained at the level of reduction and management, failing to achieve a paradigm shift toward redefining architecture as an autonomous ecological system from an organizational perspective. The systematic framework that transfers nature’s survival strategies and organizational principles—verified through billions of years of evolution—into architectural spatial systems and design processes still remains insufficient.
To address these limitations, this study redefines biomimicry from the perspectives of ‘Architectural Transition’ and ‘Spatial Organization,’ and aims to systematically elucidate the spatial mechanisms resulting from this transition. Here, spatial organization refers to the integrated architectural structure that determines how unit spaces and programs, boundaries and circulation, buffer zones, and networks are connected through specific hierarchies and rhythms. This structure represents the reinterpretation of ecological relationships—formed by habitats, boundaries, corridors, and buffer zones in nature—into architectural form, structure, program, and environmental control systems, and operates as a spatial field, ultimately unfolding user experiences and behaviors. From this perspective, biomimicry extends beyond the imitation of natural forms to function as a conceptual framework that transfers the organizational principles and ecological interactions of living systems into the generative logic and spatial composition of architecture. It thus provides a theoretical foundation for understanding architecture as a generative and adaptive spatial system that continuously exchanges material, energy, and information with its surrounding environment. In order to architecturally reinterpret natural ecological principles, a systematic analysis of the biological mechanisms that constitute ‘Natural Principles’ is required as a prerequisite.
First, through theoretical investigation, this study classifies five core principles: ‘Generation & Growth,’ ‘Material & Metabolic,’ ‘Adaptation & Response,’ ‘Relations & Boundaries,’ and ‘Diversity & Resilience.’ These principles are based on mechanisms by which living organisms generate form through self-organization, regulate flows of energy and material for adaptation, and continuously reorganize boundaries and internal structures through interactions with external environment. By analyzing these principles as a continuous mechanism—Generation → Metabolism → Adaptation → Relation → Resilience—from the perspectives of time and process, this study derives a concrete ‘Organizational Order of Nature’ manifested as physical entities. This order represents optimal survival strategies verified through 3.8 billion years of evolution, rearticulated a natural organizational system in which living entities form structures in interaction with their environments at the architectural level. To translate these natural operational principles beyond the level of representational analogy into a substantive architectural methodology, this study establishes four types of architectural transition through ‘Structural Mapping,’ aligning the biological analysis hierarchy of ‘Morphology–Structure–Physiology–Ecosystem’ with corresponding to the construction layers of architectural space. This framework traces how abstract ecological orders of nature materialize into physical and spatial architectural entities, and analyzes how each transition type operates within spatial organization. The four transition types identified are: Generative Integrity in morphological transition, in which biological forms, patterns, and geometric growth rules are transferred into architectural mass and spatial form; Synesthetic Depth in material transition, in which the stratified organization and material variability of biological tissues are translated into architectural materials and envelope systems; Fluid Flow in functional transition, in which biological metabolic and adaptive functions are transferred into environmental control and performance systems; and Multi-layered Connection in system transition, in which the cyclical and networked structures of ecosystems are translated into architectural programs and urban connectivity.
Second, to clarify the mechanism by which natural organizational principles are translated into architecture, this study proposes a six-stage ‘Biomimetic Architectural Transition Model,’consisting of : Problem definition – Exploration of operating principles – Extraction of design language – Morphological organization – Spatial organization – Architectural implementation. This model redefines climatic, environmental, and programmatic constraints as functional challenges that nature has already resolved, and proceeds by identifying corresponding biological operating principles and abstracting them into design languages, such as architectural concepts and geometric rules. In particular, the model explicitly structures the stage of ‘Spatial Organization,’ which has been overlooked in previous methodologies, thereby presenting a pathway where abstracted design language evolves beyond forming the morphological skeleton of the mass–void and materialize into an integrated spatial system in which internal boundaries, circulation, and networks are organically interwoven. The proposed six-stage model functions both as a theoretical framework explaining how the four organizational categories of nature are transformed into architectural entities and as a generative design tool capable of translating and validating natural principles within architectural practice.
Third, the case studies selected include Eastgate Centre, Eden Project, 30 St Mary Axe, Beijing National Stadium, Masdar Institute, and the National Museum of Qatar—representative projects designed and constructed from the late 1990s to the present that translate natural organizational principles or ecological mechanisms into architectural concepts and spatial systems. By applying the ‘Biomimetic Architectural Transition Model’ to each case, this study investigates how architectural transition operates at each stage of the sequential mechanism—from problem definition to architectural implementation. Particular emphasis is placed on analyzing how morphological, material, functional, and system transitions do not exist independently, but rather overlap and integrate to form distinctive spatial organizations. The analysis identifies four core architectural transition characteristics: ‘Generative Integrity and Topological Continuity’ in morphological transition, ‘Synesthetic Depth and Responsive Mediation’ in material transition, ‘Fluid Flow and Cyclical Modulation’ in functional transition, and ‘Multi-layered Connection and Urban Resilience’ in system transition.
Fourth, as a supplementary verification process, AI-based architectural transition structure generation experiments were conducted using DALL·E 3 as a tool. By inputting identical variables corresponding to the six-stage model—Natural Principles, Abstract Principles, Design Language, Morphological Organization, Spatial Organization, and Architectural Implementation—the transition sequence was visualized and structurally compared with transition flows derived from the case analyses. This process functioned as an auxiliary procedure to validate the reproducibility and logical consistency of the proposed model.
Synthesizing the theoretical framework, case analyses, and AI-based supplementary validation, this study demonstrates that biomimetic architectural transition characteristics grounded in natural organizational principles are spatially manifested as four key spatial characteristics: (1) Field of Non-linear Topological Continuity, (2) Synesthetic Resonance of Boundary, (3) Cyclical Temporality of Flow, and (4) Autopoietic Polylogue. The ‘‘Field of Non-linear Topological Continuity’ form experiential spaces in which interior and exterior, structure and form are organically interconnected through gradual gradients and overlapping zones rather than fixed walls. ‘Cyclical Temporality of Flow’ is based on self-regulation, through which buildings perceive environmental stimuli and autonomously adjust their form and state, establishing environment- responsive system of ‘Flexible Order’ that evolves over time beyond fixed singular purposes. ‘Synesthetic Resonance of Boundary’ emerge as materials and envelopes filter environmental elements to provide ecological buffering and synesthetic experiences. ‘Autopoietic Polylogue’ create closed-loop networks of circulating energy and information, enabling architecture to operate as an integrated organism resonating with urban ecosystems. Accordingly, The architectural transition space of biomimicry is defined as a ‘Generative Adaptive System’ that embodies the multi-layered hierarchy and continuity of natural organization, autonomously reconfiguring and reorganizing itself in response to environmental changes and user activities.
This study constructs an integrated methodology by classifying natural ecological organizational systems into five principles and systematizing them through four transition types and a six-stage ‘Architectural Transition Model.’ Furthermore, by reinterpreting natural principles from the perspective of ‘Organazational Cross-Transition,’ in which form and function, material and system are organically interwoven beyond the simple application of elements, spatial organization is redefined as an ‘Architectural Ecological Structure’ in which ecological networks and experiential layers are condensed. In doing so, this research expands the discourse of biomimicry beyond technical performance optimization, or morphological mimicry, positioning it as an ecological transition framework that translates natural order into multi-layered spatial systems. This perspective holds significance in providing a practical methodological foundation for understanding architecture as an evolving organic entity that interacts with its environment in response to climate crisis and the fragmentation of urban ecosystems.
