Liquid Architecture: Cultural Narratives, Spatial Metaphors, and the Evolution of Fluid Form
Abstract: Liquid architecture represents a fundamental rethinking of architectural space, moving away from the long-standing assumption that buildings must be static, permanent, and formally fixed. Rather than understanding architecture as an object defined by rigid boundaries and stable geometry, liquid architecture proposes space as a fluid condition shaped by movement, atmosphere, perception, and cultural meaning. Rooted in cultural theory, phenomenology, and spatial anthropology, this approach views architecture as an evolving narrative …
