The structure of traditional markets in Indonesian is getting massive and solid since it always finding a new potential direction for sustainable form. The uses of material and technology are dominated by how the building was built and controlling how peoples live within the environment. In contrast, the interaction between human with nature and the environment are often ignored. The need for a healthy traditional market has become a major issue recently, but most of the current traditional market concepts suggest otherwise. The idea of this paper is to reconsider the concept of the traditional market, drawing on Hill's theory of immaterial architecture which presents the significance and importance of the immaterial as material in architecture. This study begins by observing daily practices in traditional markets to explore possible immaterial aspects and then discovering potential mechanisms of those aspects. The aim is to explore the possibilities of immaterial aspects of transforming the concept of the traditional market from social-cultural into socio-eco tropical space.
