Nic and his skilled team were instrumental in delivering our new business premises on time. They arrived early and stayed late. Excellent communicators and very reasonable $$.  Pleasure to deal with and I highly recommend.

Nic Jouin, the principal builder and founder of Permastructure has worked with Australian Hemp Masonry Company's hempcrete materials since 2016. Prior to arriving in Australia from France he had had experience in the French hemp construction industry and that thorough understanding of the materials translates to beautifully finished hempcrete installations with real attention to detail. Easy to collaborate with, he and his team bring precision building and a great attitude to any building site.
