Ingrid Vaca Diez is on a mission to build better homes for the poor.
With few funds and little support, she uses the only resource she can find in abundance - empty plastic bottles.
Her own life in Santa Cruz, Bolivia, is one of relative comfort but she is shocked by the rising level of poverty she sees around her.
Though completely self-taught, she designs and builds new homes using recycled plastic bottles filled with dirt as the “bricks”. So far, she has built 10 of these homes.
The people she is trying to help are rural, indigenous migrants, often living in single room, dirt floor shacks.
