1. Check the fit
Read the land, climate, water, budget and experience assumptions before using any figure or layout.
2. Verify before spending
Use the land, council, site, water and contractor questions to close dangerous gaps with the relevant authority or qualified professional.
3. Build in order
Follow dependencies, cash gates and “do not proceed” checks instead of starting several unfinished systems at once.
4. Keep the working copy
Read on the web, save progress and download the available PDF or workbook. Check the version and price-review date each time you return.
