C-K Theory is currently one of the most sophisticated theoretical frameworks for modelling design processes. Based on the interaction between a space of concepts, C, and a space of knowledge, K, it accurately describes the mechanisms of producing and transforming design objects. However, certain concepts used in architectural practice remain difficult to integrate into this model. This is the case with the architectural concept (architectural parti in French), which is frequently presented as a decisive stage of the project, yet its theoretical status remains unclear. This article aims to shed light on this difficulty based on the hypothesis of a general system in Bertalanffy’s sense. Previous research, which has highlighted an isomorphism between the wuxing of the Chinese tradition and Platonic solids, is employed as a heuristic tool to identify several structuring properties of this system: duality of transformation regimes, dynamic antagonism, the role of the 5th polarity, and the activating centre… Comparing these properties with the CKT leads to the identification of a central mediating mechanism, which is scarcely explained in its classical formulation. We interpret the architectural scheme as this very mechanism, this bridge that ensures the transition between the exploratory regime of space C and the stabilising regime of K. The study of this bridge leads to the formulation of the hypothesis of a third modality of rationality, complementary to the causal and correlative reason described by Vandermeersch. This rationality, referred to here as ‘bridging reason’ in reference to M. Serres, denotes the capacity to establish relationships between heterogeneous domains to enable the emergence of new configurations.
