We have worked on eight Earth Structures buildings now and are about to start the ninth! We work to very high standards and share a positive relationship with the company. We value their help in the design process as well as their work ethic. They have been in the business for twenty years and know their stuff backwards. I like the material so much we built our own house using Earth Structures and love it. — Mathew Kirley – Mathew Kirley Builders. Mansfield, Victoria
