The document proposes a model to upgrade slums in urban areas of India in a regulated manner. It suggests creating a government organization with different roles like development controller, construction manager, and finance controller to oversee projects. Civil engineers and workers from local slums would implement the projects. The $300 house model promotes affordable, sustainable, and replicable housing. The organization would target slum regions one by one to systematically reduce slums across cities. Challenges like social, environmental, and time factors would be addressed to ensure smooth implementation. The model is estimated to reduce slum population by 6% annually if applied for 5 years through coordinated efforts.
