Planned City Extensions can prevent the leap-frogging over vast areas that generates wasteful and speculative areas within the city and results in prohibitive costs for urban services and infrastructure provision in distant places. When deployed next to existing neighbourhoods, these planned extensions offer urban dwellers the possibility to live, work, rest and play in close proximity to consolidated urban areas. This first lever of change contributes to more efficient and sustainable development patterns steering urban expansion towards areas that are more suited for positive urbanization.
