This study aims to revive and reframe the study of regional architecture oriented housing policies of local sustainability, from the use of unconventional materials associated with low economic costs and reduced environmental impact. This redefinition is to give people access to low-income homes to own, taking into account the use, morphology, material resources and other characteristics of natural places where such architectures can be developed. Given the lack of sustainable housing policies in major metropolitan areas of Brazil, this study is presented as a way to go for science today, which may promote the perception that nature will do, primarily, for the enjoyment of those who live in spaces. The City of Rio de Janeiro, because of its uniqueness as the City of Nature will be the cut worked, since joining the urbanity with its immense natural potential discarded by various public policies. Nature carioca can generate, through public managers, the democratization of housing in the city with clean use of sustainable materials in the production of residential units affordable. Currently are used almost exclusively, construction materials bound in the modern period of the twentieth century that degrade the environment. We can say that the use of these materials in the twentieth century has become a tradition of modernity associated with the ideas of progress and development. Among the potential materials offered by nature carioca should emphasize raw land and bamboo, materials which have for centuries supported the survival of man in Brazil and the world. In this context, we conclude that the solutions for the generation of sustainable housing adapted to the specificities of Rio (and Brazil), should emerge from this space through their labor, materials and techniques peculiar, reflecting a major reinterpretation the interaction between man, technology and nature.
