The title of the project is Affordable Housing for the Bottom of the Pyramid. The land cost in urban cities is shooting up day by day as the availability of living space is becoming scarce. This forces the immigrants, or the bottom of the pyramid people to force themselves into temporary living setups, which in turn increase the slums in the cities.The project is trying to provide a housing option for these people, who have very low incomes and are mostly migrants. Various Slums were studied for understanding the lifestyle of migrants belonging to various categories like hedonists, settlers, risers, etc. From different layouts, three layouts were selected as the final layouts of the house, and a working model of one of these layouts was made to get the feedback of the users. We followed the approach of experiential learning, and based on our own experience inside the house, we modified it to suit the needs of the actual user category. The main focus throughout the project was to efficiently use each and every cubic metre present inside the house. For this, various spaces that can be used for multiple purposes were identified and designed according to the incremental needs of the user. The outcome of this project is the prefabricated DIY units, which actually make the user the creator of his space. Provisions were also provided for the user to bring in his own furniture or equipment and place it effectively in the house in such a way that it does not eat up much space.
