an integrative design science for sustainable human communities


Permaculture Design allows us to integrate all the complexities involved in sustainability; Water, energy, construction, primary production, spatial planning, land management, resource management, pest control, waste management, nature conservation and all the other elements that raise issues for our survival, and our need to achieve true sustainability.


Since moving to Bali in 2000, Norm has been working full-time on diverse projects & programs, from running an environmental NGO, to developing ecotourism businesses, to implementing better sanitation systems in post-tsunami Aceh and recently, a reef protection program in Raja Ampat, West Papua


Norm designs, builds and works with local communities. He believes that polarization is stopping progress, that we can only ever achieve true sustainability, by merging a new and ethical business philosophy, with the real needs of society, and a genuine care for the environment
