Lowtech Graph lists low-tech options for every need of a home. Here you can compare them, find tutorials to build them, and link them together into a circular system. Why low-tech?
Defensible space / vegetation management
Passive
One of 2 ways to meet this need. Cost, carbon, footprint and rankings are relative to other solutions for the same need, not absolute.
Clearing and managing the plants around the house so a fire cannot easily reach it. Nothing that burns stays right against the walls, plants nearby are kept low and spaced, and trees are thinned further out. A wildfire loses its fuel before it reaches the house.
Levels are relative to the other options for this need, not absolute. Fewer dots is lighter.

Upfront cost: Low · Skill to build: Basic · Upkeep: Light · Change to daily life: None · Works without the grid: Yes Choose it if you want to stop a wildfire reaching the house through the land around it.
Fire-rated compartmentalization Can I use it? Works in a flat · No rebuilding needed What does it cost me? Upfront cost: Medium · Skill to build: Basic · Upkeep: Light · Change to daily life: None · Works without the grid: Yes Choose it if you want to slow a fire inside the house and keep an escape route open.
We don’t list sizing or quantities, as the yield of each technique depends on the quality of its build. The catalogue compares options but doesn’t dimension them. Regulatory notes are indicative, with a French example, and need to be confirmed locally.
