What you will learn

Learn how to combine traditional cob building with waste materials to create unique, sculptural, low-impact bottle walls.

‘Ecobricks’ are bottles stuffed with un-recyclable plastic. This contains the waste plastic, preventing it from going to landfill or into our seas. The stuffed bottles can then be incorporated into cob walls to become an innovative, attractive, insulating building material that can be disassembled and reused.

Other materials will also be introduced in the foundation and roofing stages as we create a cob bottle building from earth and waste.

Using plastic and other ‘rubbish’ in building is a great way to raise awareness of the issues at the same time as taking them out of the waste stream.
