DIY Housing (UPDATED)
A housing unit to make entrepreneurs of slum dwellers.

Solution

The designed house uses locally buyable materials like cement, sand, chicken mesh and used plastic bags. The plastic bags are tied at ends and wowen into a fabric and encased in the chicken mesh to give the concrete walls / flooring stability and also reduce weight. 


The pre fabricated components can be made onsite at any location / city and this can be replicated anywhere in the world. The moulds for the pre fabricated cement panels are Roto Moulded Components. This could enable low cost rapid deployment anywhere. 

Seeing the situation of the slums of Mumbai, I had to add in the dish. Everyone has a TV here. 

Internal furniture can also be moulded / pre fabricated.
