Principles refer to standards or prescriptions for working with or arranging various elements to produce the intended landscape design Adelaide. Good landscape design follows a combination of seven principles that are unity, balance, proportion, focalization or emphasis, sequence or transition, rhythm, and repetition. First of all, unity refers to the use of elements to create harmony and consistency with the main theme or idea of the landscape design. Unity gives the landscape design a sense of oneness and interconnection. Unity in landscape design can be achieved by using plants, trees, or material that have repeating lines or shapes, a common hue, or similar texture.

Basic principles that are must for good landscape design:

Balance gives the landscape design a sense of equilibrium and symmetry in visual attraction. There are three ways by which balance may be presented in landscape design. Symmetrical or formal balance is achieved when the mass, weight, or number of objects both sides of the landscape design are exactly the same. Asymmetrical or informal balance in landscape design suggests a feeling of balance on both sides, even though the sides do not look the same. Asymmetrical balance in visual attraction may be achieved by using opposing compositions on either side of the central axis.

Proportion describes the size relationship between parts of Adelaide landscaping design or between a part of the design and the design as a whole. A large fountain would cramp a small backyard garden, but would complement a sprawling public courtyard. Additionally, proportion in landscape design must take into consideration how people interact with various components of the landscape through normal human activities. Focalization or emphasis directs visual attention to a point of interest or prominent part of the landscape design. Emphasis in landscape design may be achieved by using a contrasting color, a different or unusual line, or a plain background space.

Paths, walkways, and strategically placed plants lead the eye to the focal point of the landscape without distracting from the overall landscape design. Sequence or Transition creates visual movement in landscape design. Sequence in landscape design is achieved by the gradual progression of texture, form, size, or color. Moreover, the rhythm creates a feeling of motion which leads the eye from one part of the landscape design to another part. Repeating a color scheme, shape, texture, line or form evokes rhythm in landscape design. Finally, repetition in landscape design is the repeated use of objects or elements with identical shape, form, texture, or color. Although it gives the landscape design a unified planting scheme, repetition runs the risk of being overdone.
