The fact that the formal sectors had not been able to accommodate workers implied the importance of informal sectors, one of which was street vendors. Embracing irregular occupancy in public spaces—usually within large numbers, street vendors were a phenomenon of informality that most of the time treated as damage to the city's image. Their chaotic expressions were currently resolved by relocating into specific areas, sometimes to no avail, and creating permanent spaces that tended to be monotonous, such as a kiosk. This study aimed to create an order by configuring street vendors into modules based on their charac-teristics and temporary activities while preserving their informal identity within their context. The concept of permeability and adapt-ability provided a qualitative approach to support pedestrian flows needed by the street vendors. Observations exposed the ever-changing street vendors' habits; at the same time, visual questionnaires revealed that the distinction of the street vendor was related to consumers' visibility and perception of their prominent informal identity. Explorations of module configurations utilize Rhinoceros and Grasshopper to get design strategies. The results are high visibility, a high level of physical accessibility, good access points, a grouping system, and spatial relationships within the context they occupy. These results were supported by analyzing visibility and connectivity using depthmapX. In order to create a practical configuration, the study was held in a chosen site of a commercial area in West Jakarta, in which street vendors occupied the area permanently and had regular pedestrian flow. The result would create a new layer in the street vendor center, which was inclusively accessible within its context while framing each of the vendors' informal identities. The implementation of this study would be an alternative solution in public spaces where cities coexisted with informality.
