Cities, not only growing in magnitude but more importantly in rates of change, require new urban systems which act as a counter-model to traditional master planning techniques. The introduction of evolutionary thinking into urban strategies was developed by Sugar Inc. to address the current population growth of London. A computational urban system, formed by instrumentalising generative forces of the city into a genetic code, produces an organizational and evolutionary process, which contains a varied range of intensive (i.e. programmatic) and extensive (i.e. dimensional) properties. Through responsiveness to contextual dynamic parameters and feedback process of the system itself, this urban process has no pre-planned stages of development, proposing a radically different model to traditional notions of Master Planning.
