In 2010, in Japan, the average number of people per house was set at 2.0. It is a fact that the traditional family home has changed dramatically. Understanding as the traditional home the one made by parents and children and in some cases some member of the previous generation.
The individualistic tendency of the society is happening worldwide, but in a more pronounced way in Japan. Another fact supporting this theory are the 32,000 people who died in 2010 in Japan, discovered by the authorities and that were not claimed by their relatives or friends.
With these figures as an argument, our purpose is to think about different ways of understanding collective housing, paying special attention to the understanding of the "collective". It is intended to work with a unit of 400 people, that would be thought as a community and to investigate what that implies in a spatial, functional, social, urban and energy way. The project will conclude with the inset of the research in a plot on the Carabanchel extension area.
