Although Cape Town city in South Africa is generally regarded as the most stable and prosperous city in the
region, there are still approximately 7.5 million people living in informal settlements and about 2.5 million
housing units are needed (reference to website excluded for review). This motivates the so-called Empower Shack
project, aiming to develop upgrading strategies for these informal settlements. To facilitate the fulfilment of this
project, urban design prototyping tools are researched and developed with the capabilities for fast urban design
synthesis. Therefore, with this paper we present a computational method for fast interactive synthesis of urban
planning prototypes. For the generation of mock-up urban layouts, one hierarchical slicing structure, namely, the
slicing tree is introduced as an abstract representation of the parcels as an extension of the existing generative
method for street network. It has been proved that our methods can interactively assist the urban planning process
in practice. However, the newly introduced data structure has several limitations and hinders the further
improvement of urban synthesis. In the future, the development of a new data structure is required to fulfil
the optimization methods for urban synthesis and evaluation strategies should be enabled to fully realize the
computational support.
