TOWARD TEMPORAL AND PUNCTUAL URBAN REDEVELOPMENT IN DYNAMIC, INFORMAL CONTEXTS An Adaptive Masterplan Driven by Architectural Interventions Using Multiagent Modeling TREVOR RYAN PATT 1 Singapore University of Technology and Design, Singapore 1 trpatt@gmail.com Abstract. This paper presents design research speculating on new plan- ning approaches for informal urban sites that enables coordinated plan- ning to operate within the realm of spontaneous, bottom-up redevelop- ment. In opposition to the /tabula rasa/ Modernist development, this project reacts to the dynamic metabolism of the village and engages with the rapid turnover of the built environment of the village as a mechanism through which to implement incremental redevelopment. A radical re- orientation of the object of masterplanning, this replaces the singular im- age or document as the guiding authority with a collection of opportunis- tic adaptations, temporal sequences, and localized procedures. Enabling this approach is a computational approach that analyzes the morphology of the public space network to identify opportunities to address issues in the composition of the village. A multiagent system driven by weighted random walks through the circulation network conducts local analyses of the urban fabric while changes are made and proposes potential mod- ifications to discrete areas. The model simulates the potential for such a planning tool to be used over a long time span and updated with em- pirically gathered data, having the benefit of flexibility and resilience in the face of the changing and unregulated conditions in the context of informal urbanism.
