Our Approach

Our history

The Australian Hemp Masonry Company has been working in the hemp construction industry in Australia since 1999.

All our products were developed and tested over a six-year period at the Australian Centre for Construction Innovation at the University of NSW and then for a further six years in the field. As a result of this extensive testing, we now have Hemp homes all across Australia’s varied and extreme climates.

Our Lime Binder, Hemp-lime Render and Insulation products are manufactured in Sydney, Australia.
