This article is motivated by the fact that in Cape Town, South Africa, approximately 7.5 million people live in informal
settlements and focuses on potential upgrading strategies for such sites. To this end, we developed a computational
method for rapid urban design prototyping. The corresponding planning tool generates urban layouts including
street network, blocks, parcels and buildings based on an urban designer´s specific requirements. It can be used
to scale and replicate a developed urban planning concept to fit different sites. To facilitate the layout generation
process computationally, we developed a new data structure to represent street networks, land parcellation, and the
relationship between the two. We also introduced a nested parcellation strategy to reduce the number of irregular
shapes generated due to algorithmic limitations. Network analysis methods are applied to control the distribution of
buildings in the communities so that preferred neighborhood relationships can be considered in the design process.
Finally, we demonstrate how to compare designs based on various urban analysis measures and discuss the limitations
that arise when we apply our method in practice, especially when dealing with more complex urban design scenarios.
