In this project, I have used glass beer bottles and 1.5 liters cold drink PET bottles (along with general building materials) to build a house! The PET bottles are filled with sand and the glass bottles are empty. The glass bottles will act as an insulator to protect against solar radiation.
Instead of using bricks, using bottles adds a unique kind of interior and exterior decoration. Plus, it’s a clever and creative way to reuse waste materials!
