TO GO WITH AFP STORY BY JOSE BAUTISTA - People stand over the prototype of a floating house during its presentation at the Reservoir of Penol in Guatape municipality, Antioquia department, Colombia, on November 29, 2011. Medellin's EAFIT University students modified the design of amphibious houses used in the Netherlands and Canada to make it affordable in the Colombian context. A floating house designed on a platform made of plastic bottles was created to provide a cheap housing solution for families affected by floods in Colombia.
