Andreas Keller, a master's student in South Africa, wanted to find an environmentally friendly way to improve people's living conditions in the country's shanty towns.
The idea he came up with is the eco-friendly i-Shack - insulated with cardboard, complete with a rainwater harvesting system and solar-powered electricity.
Thanks to a grant from the Bill and Melinda Gates Foundation, there are plans to build 100 more i-Shacks.
