A home for sustainable building alternatives
We research and develop sustainable, innovative, socially inclusive, affordable and robust construction systems that dramatically lower carbon emissions, reduce waste, increase efficiency, create low-skilled work opportunities and restore natural ecosystems.

“Sustainability is a value word and like all value words – freedom, fairness, beauty, justice it is subjective, nearly impossible to define, but possible to sense (or to sense its absence), and vitally important.”
- Donella Meadows
