This project proposes a generative model for a layout of an organic settlement, in particular fishermenis settlements. It attempts to harness and integrate some of the qualities of organic design process into computer-aided design, capture the complexities of an organic solution and apply it to the housing design decisions. The two complementary fields of Shape Grammar and Generative Evolutionary Design have been converged for this purpose. Shape Grammar is used to extract the style and aspects of organically evolved fishermanis housing settlement. Generative Evolutionary Design which uses genetic algorithms as a search mechanism is used to explore alternatives and to evaluate the generated design for its functional and usability values and identify the fitter solutions.
