Architectural historiography has evolved in recent years, embracing a more inclusive approach that incorporates diverse voices and representative viewpoints. Despite these progresses, knowledge gaps, errors, and distortions persist in both existing architectural history and global history. This paper challenges the long-held assumptions such as style and movement in mainstream history survey and outlines a new methodological roadmap for global architectural historiography. It highlights three essential attributes that differentiate architecture from other aesthetic objects (such as painting and sculpture) and design products (such as cars and furniture): architecture orders bodily activities and conditions human existence ; architecture necessitates the integration of tectonics, technology, material, and labor in construction; and architecture serves as a collective expressive medium, influenced by and contributing to the interaction between various social forces. The new triological methodological approach mirrors but goes beyond the Vitruvian Triad, with the existential replacing utility, the constructional replacing solidity, and the interactive replacing beauty.
