About the project

The 3C Eco-house is a project that is changing the game for sustainable building materials and access to housing, while employing women and young people from underserved communities in the process.

Developed by 3C Construcciones, an Argentinian social enterprise, it allows to turn any plastic waste into eco-blocks (Block 3C)for building beautiful, fully-fledged houses. 3C’s method doesn’t require any water or electricity, and it’s suitable for unskilled labourers.

The formula

WHAT IF you could build houses with plastic waste?

3C Eco-house is a project that provides affordable, high-quality building solutions, generating a social, economic, and environmental impact. The process, machinery, and technology have all been tested and certified to comply with quality construction requirements.


100 big plastic bottles (PET) = 1 Block 3C
1  60m2 house = 85-90 Blocks 3C of 3 assembled components
1  60m2 house = 1.026 kg of plastic waste = 27.000 plastic bottles recycled

This is a Premium Blueprint developed in alliance with this project’s original creator.

This means that you can replicate this process with a dedicated, interactive toolkit that will enable you to learn about the project, its step-by-step process and how to adapt it to your own context.
