This 624-square-foot bungalow utilizes quite an innovative construction process: it's put together with sand-filled plastic bottles, each one capped and weighing about two pounds.
This project is a partnership between the NGO Development Association for Renewable Energies (DARE) and foreign experts from Africa Community Trust, a London-based NGO. Filled plastic bottles of sand are stacked into layers and bonded together by mud and cement, and held together by a network of strings to provide extra support to the structure.
The structure is fire proof, bullet proof, earthquake resistant, and highly insulated. The builders claim the sand-filled bottles are stronger than ordinary cinder blocks. This home requires an approximate 14,000 bottles, a small number compared to an estimated 160 million disposed of each year by the country of Nigeria.
