ABSTRACT
This chapter focuses on one of the central dimensions of non-programmatic planning: space. It identifies basic guiding principles by focusing on processes of spatial development on undeveloped ('greenfield') sites. The chapter shows how the same principles can be applied to other South African urban challenges: upgrading informal settlements, restructuring poorly performing parts of cities, and intensification. The way in which settlement formation occurs can be demonstrated through a sequence of diagrams which trace processes of urban growth from the bottom up. Public space lies at the heart of non-programmatic approaches to settlement-making. Many countries have introduced movement classifications, particularly in relation to the vehicular movement system, as part of transport management strategies. Clearly, great care needs to be taken around the use of classification systems. Their main usefulness is that they can help in an understanding of capacity and scale and to resolve inherent tensions between 'mobility' and 'accessibility' routes.
