India's Tata group says it will launch cheap housing that can be built within a week for 500 euros, according to Indian media reports.
A spokesman for Tata, which in 2009 launched the world's cheapest car, the Nano, said the pre-fabricated houses would help the rural poor buy a home.
Prototypes are already being tested with a view to launch by next year, the PTI news agency said.
Indian authorities say millions of homes are needed in rural areas.
