The aim of this project is to promote a lively and balanced lifestyle by mixing both public and private uses to encourage, eco – responsible living and working within Shinko Island, Yokohama, Japan. Another aim is to respond to the increasing elderly population and increase harmony with young people. As more of the city’s large population migrates to dense urban, resources are stretched, resulting in low environment quality, pollution and inferior living. My aim is to provide high quality environments by focusing on public spaces and lively streetscapes. I think of a house as something that an architect designs or urban planning in conjunction with people like a family. What we design is a method of living for the people, the smallest social unit to connect with or maintain its distance from another block . In Japan, as in many asian countries the family unit lives together in the same house. Structured vertically, I tried to dispersed each unit in a hierarchy. Also I want to make the housing more intimately connected with its environment by utilising traditional Japanese concepts like Tatami, Engawa, unpaved road and gardens. Therefore this environment will be conjunction in design. It also enabled inhabitants to build their own community. As new units can be added as the family grows, visitors and residents will be stimulated by the way their environment evolves in time.
