The Design Tool
Find your land and trace its boundary. The tool reads the terrain, climate and soils, finds valleys and estimated keypoints, then walks you through Yeomans' Scale of Permanence — climate first, soil last.
Step one — locate
Find & draw your property
Keyline plans are made for one piece of land at a time — every recommendation here starts from the boundary you draw.
Step two — measure
Terrain analysis
After Yeomans: the keypoint is where a primary valley's lower, flatter floor suddenly steepens. The keyline is the contour through it.
Scale of Permanence — most permanent
Climate
Climate tops Yeomans' scale because it is the one factor a landholder cannot change — only design around.
Scale of Permanence — third
Water
"Once you've created the right hydrological balance, 70% of the work is done." — Sepp Holzer, Water Is Life (Tamera film, English translation)
Scale of Permanence — fourth
Access & roads
After Yeomans: roads follow ridgelines and water channels, so each earthwork serves two purposes.
Scale of Permanence — fifth
Trees
After Yeomans: belts of trees follow the water lines and ridges, turning every earthwork into a sheltered planting strip.
Scale of Permanence — sixth
Buildings & structures
Mollison's zones radiate out from the home (Zone 0) by how often each place is visited.
Scale of Permanence — seventh
Subdivision & fences
Mollison: each element performs many functions, and each important function is supported by many elements.
Scale of Permanence — last, because it is the outcome
Soil & goals
Soil sits at the bottom of Yeomans' scale not because it matters least, but because deep, living soil is what the other seven layers produce.
