The graduation project investigates what makes a housing block and designs a tool, that can generate and evaluate the block informed by a predefined scenario. In my case a block in which places for human and animal species are equally negotiated. After a time of rapid urbanization leading to a devastating segregation from nature, humans need to develop symbiotic approach of sharing environment with the wildlife and our-life. Because of modern agricultural techniques, pesticides, monoculture and habitat loss, population of some species has dropped drastically. The graduation project investigates innovative ways in which urban design can attract and increase diversity of species.
