Planning Tools
Measure it before you build it.
Four planning tools built from the same standards we use to design compounds. Each one shows its math and explains why the numbers matter.

Open SuppliesSelf-Sufficiency Calculator
Water, food, solar, batteries, fuel and heat for your household, sized for 90 days, 180 days or a full year.
Open HealthMedicine and Nutrition Planner

Open Below gradeShelter Configurator
Size below-grade quarters for your household: square footage by room, filtered air, earth cover and protection factor.
OpenThe standard behind the tools
Through a full winter, on your own.
The tools default to 180 days because that is what we build to: long enough to carry a household through a full winter without deliveries, utilities or outside services.
Numbers are the beginning.
A consultation turns your results into a site plan, a system design and a schedule.
