What we distinguish
Exact geometry has a definition that can be checked. A rectangle has right angles; a golden rectangle has a particular side ratio. Visual inspiration borrows an impression without claiming to meet that definition. Both are valid design approaches when described honestly.
Our diagrams are explanatory schematics, not surveyed plans. Photography illustrates texture, edge conditions and visual relationships; it does not establish dimensions, compliance or a verified mathematical construction.
How to use the reading
Begin with the principle closest to your problem. Sketch a small number of alternatives, mark the important dimensions and test the preferred option on the ground. Use temporary lines before permanent edges. Check plants against local conditions rather than choosing them solely for a shape.
Sources are linked near the relevant discussion. Mathematical definitions draw on references such as Wolfram MathWorld. Horticultural starting points include the Royal Horticultural Society. Official garden and accessibility sources provide context, not an endorsement of this website.
Independence and scope
This is an independent educational website. It is not affiliated with the gardens, institutions, authors or standards bodies mentioned. References to Versailles, Villandry, the Alhambra and other places identify precedents, not partners.
We do not provide land surveys, engineering, horticultural guarantees or accessibility certification. Conditions and legal requirements vary by location. A qualified local professional is the right next step when the work affects structures, drainage, protected trees, services or regulated access.
