Landscape design: from idea to layout
Design steps: 1. Survey the site (size, slope, sun, soil, water). 2. List needs of the users. 3. Make zones (play, sit, grow, walk). 4. Draw a layout and improve it.
Good design uses simple principles: unity (parts belong together), balance (not too heavy on one side), rhythm (repeat shapes) and proportion (sizes suit each other).
Drafting: drawing so others can build
Drafting means making clear drawings with correct sizes. The main drawings are:
- Plan: the view from above.
- Elevation: the view from the side, shows heights.
- Section: a slice cut through the ground.
Scale and symbols
A scale tells how much smaller the drawing is than real life. On a 1:100 plan, 1 cm on paper is 100 cm = 1 m on the ground. Real length = drawing length x scale number.
Symbols save space: a circle is a tree, a rectangle is a building, a wavy shape is water. Line types matter too: thick for edges, thin for details, dashed for hidden things.
Reading a plan
Find the north arrow, the scale bar and the title. Measure with the scale. Check each symbol in the key. A plan with these parts can be built by anyone.
Key formulas and definitions
- Real length = drawing length x scale number
- Drawing length = real length / scale number
- Area = length x breadth
- Drawings: Plan (top), Elevation (side), Section (cut)
- Principles: unity, balance, rhythm, proportion
Worked examples
1. On a 1:100 plan a path is 6 cm long. How long is the real path?
6 x 100 = 600 cm = 6 m.
2. A pond is 3 m wide. How wide is it on a 1:50 plan?
3 m = 300 cm. 300 / 50 = 6 cm.
3. A lawn is 8 m by 5 m. What is its area?
8 x 5 = 40 m2.
Common mistakes
- Mixing units: 1:100 means 1 cm on paper is 100 cm, which is 1 m, not 100 m.
- Measuring the plan in 3D thinking. A plan shows only the top view, not heights.
- Forgetting the north arrow and scale bar on the plan.
- Drawing trees as full pictures. Use the standard symbol (circle) so the plan stays clear.
