IIT Madras students have developed a house than can be folded up and transported anywhere. It’s a two-storey house made out of metal frames and iron panels that can be unfolded and fixed to accommodate 20 people at a time. It can be set anywhere that’s flat; all you have to do is unfold its metal frames and start fixing the panels which will be the walls for the house. There are provisions for electricity and water supply as well. This construction should be especially useful when natural disasters render many homeless.
