The presented study is made for Cape Town city in South Africa, in which approximately 7.5 million people living in informal settlements and about 2.5 million housing units are needed. This motivates us to develop upgrading strategies for informal settlements. For this purpose, we developed an adaptive and interactive tool for rapid computational urban design prototyping. The tool can be used to generate urban layouts including street networks, blocks, parcels and buildings based on requirements specified by an urban designer. For implementing the layout generation process, we developed an underlying tree data structure to represent street networks and parcellings. Moreover, network analysis methods were applied for controlling the distribution of buildings in the communities so that preferred neighborhood relationships are considered. Finally we demonstrated how to compare designs based on spatial analysis.
