LEARNING UNIT 5Changing Urban Form
5.1 INTRODUCTION
In many parts of the world the overall form of larger metropolitan areas has evolved from a relatively
straightforward, monocentric structure to a ‘galactic’ sprawl with a polycentric structure – fragmented
and multimodal – characterizes by surrounding new urban spaces and settings that include edge
cities and boomburbs (Knox & McCarthy, 2014:231).

Our focus …
Following on the growth phases of urban communities to date and some basic
growth principles, Learning Unit 5 considers a few generalised models reflecting the
change of urban form over time (5.3.1). However, cities did not develop uniformly

the consolidation of our understanding of terminology is provided.
