Most landscape designers ensure that their designs have strong connections by basing them around a few fundamental shapes. Geometric entities such as circles and squares (or parts thereof) of each are commonly used. The figure below illustrates this; the grassed play area, entertaining space, water feature, and steppers linking spaces are based on a circle, while the vegetable space is formed by a square and a half square to form a rectangle.
Using strong shapes such as these can help bring a sense of unity to your work.
Dissecting circles
Dissect a circle and use individual parts in a design—half and quarter-circles, etc.
Extend the diameter and extend the tangential line to create another strong shape.
Dissecting squares
The square can be divided and subdivided at various angles to provide landscape designers with even more shapes.
This movie shows (in a rather simplistic way) how landscape designers can use shapes such as squares and circles to create a piece of landscape design.
Some more examples of designs featuring circles, squares and parts thereof.
Here are some designs based on a square or part thereof.
Here we combine circles, parts of circles and arcs, squares joined to form rectangles to create a design.
Here is a ‘before and after’ view of a design for a small space in a Parisian garden by a gCADPlus user. The focal point is based on an underlying triangular space uncovered when preparing the site for redevelopment. For more examples by this design team, visit: https://www.lesherbesfollesdannette.com/
