Anti-Constant is a design philosophy that approaches architecture through a dynamic mode of thinking, positioning time and space as equally significant dimensions within architecture—namely, Space-Time Design. Just Like the dancer captured in the image, constantly shifting between different postures, time endows space with dynamic vitality, manifested through long-term adaptability, individual perceptions, and the uniqueness of each momentary experience.The emergence of the internet and artificial intelligence has intensified autonomy and variability in contemporary society, requiring architecture to continuously respond to changing social demands. Architecture must therefore move beyond a singular worship of space. By incorporating time as an active dimension, architecture is placed within uncertainty, opening up new possibilities for individual agency. As a result, architecture, architects, and users can enter an unprecedented bidirectional and interactive relationship.
