In the context of Australian commercial construction projects, a "hip" refers to a specific type of roof design. A hip roof, or hipped roof, is characterized by having all sides slope downwards towards the walls, usually with a gentle slope. This design typically has no vertical ends, and the "hip" refers to the external angle where two adjacent sloping sides of the roof meet. Hip roofs are known for their stability and durability, making them a popular choice in areas prone to high winds. They also provide better drainage compared to flat roofs, which can be advantageous in regions with significant rainfall.

A hip roof has four sloping sides, with each side meeting at the ridge or peak. The slope of the hip roof is typically steeper than a gable roof, providing better resistance to wind and rain. The hip roof design also offers a more aesthetically pleasing appearance compared to other roof types.

In commercial construction projects, hip roofs are often used for their structural stability, durability, and aesthetic appeal. They can be constructed using various materials, including metal, tile, or shingles, and can be designed with different roof pitches and configurations to suit the project's requirements.

It is important to note that the definition and usage of "hip" in construction may vary slightly depending on the specific project and local building codes. It is always recommended to consult with a qualified architect or engineer for accurate and detailed information regarding hip roofs in Australian commercial construction projects.
