I've written 'Permaculture Design - a Step-by-Step Guide', to explain how to go about putting a design together. While there are plenty of excellent books already written about permaculture, I hadn't found one that really explained the design process in a step-by-step fashion from start to finish. This was a gap I initially filled on my design courses with a set of worksheets, which were then tried and tested by 15 groups of design course students over 18 months, before being turned into this guide.
I've written the guide as a practical and portable companion to other permaculture books. While it includes the ethics, principles and philosophies, it places them directly into the context of the design process. It also provides clarity about where different tools and techniques can be effectively applied in the overall scheme of things.
