These houses were built in Santa Cruz, Bolivia.
The walls are built with plastic bottles, mortar, sand, clay, rubble, water and lots of community work. The concept is similar to the adobe construction technique.
The bottle walls are very strong and have also been used in Honduras and Bolivia to build water reservoirs for as much as 20.000 litres.
The bottles are filled with sand, soil or debris and are tied to each other with a nylon thread.
