Urbanization happens (Figs 11.1, 11.2). Old settlements expand and new settlements are founded. It can be a consequence of increased wealth, population growth or smaller households. This chapter considers the need for new settlements, EID for the urbanization process, how urban land-uses should be fitted together, and how new settlements should be fitted into the landscape. Buildings have rooms and corridors. Towns have land-uses and streets. The comparison (Fig. 11.3) might lead one to think that urban design is simply architecture on a heroic scale. That would be an error. Towns are organic and buildings inorganic. Where life processes are involved, planning differs. Many of us have houses and families. Both require planning, but only one of them can be strictly controlled, as stern parents will always discover. Architecture or engineering can rest on a single controlling vision; good urbanization requires attention to many visions and many processes. Final designs are not possible.
