In the context of landscape design or analysis (which seems relevant given your interest in commercial landscape maintenance), a landscape is typically broken down into four key parts or elements. These are commonly recognized in landscaping theory and practice:

1. Landform – The natural or man-made shape and structure of the terrain, including hills, slopes, flat areas, or constructed features like terraces and retaining walls. It defines the physical foundation of the landscape.
2. Vegetation – Plants, trees, shrubs, grasses, and flowers that add life, color, and texture. This includes both native and cultivated species, crucial for aesthetics and ecological balance in a commercial Sydney landscape.
3. Water – Features like ponds, streams, fountains, or irrigation systems. Water elements enhance visual appeal, provide functionality (e.g., drainage), and support plant life, especially in Australia’s variable climate.
4. Structures – Human-made additions such as paths, patios, benches, walls, or lighting. These hardscape elements provide usability, define spaces, and complement the natural components.

These four parts work together to create a cohesive, functional, and visually appealing landscape, whether for a commercial landscaping property in Sydney or elsewhere.
