The apex is the highest point of the roof, where the rafters join.


A bay is the space between the main vertical poles in a building. See the following examples:


A roof overhang which provides additional shelter over the entrance or opening to a shed.


Cladding is the material that covers your external walls and roof. Pole sheds are generally clad in profiled steel, but can incorporate ply, weatherboard, or basically any cladding material.


A flashing is typically a folded steel component that drains or deflects water back outside the cladding system.

Floor area

The length multiplied by the width of your building. This can also include extra floor area if your building has a mezzanine floor.

Gable roof

A gable roof features two roof sections which come together to form a triangle.


A timber section fixed horizontally to the vertical poles/posts to provide horizontal support.

Importance Level (IL)

The importance level rating is determined by the intended use of your building, its location and the risk it poses to human life and other structures around it. IL1 is used for non-habitable buildings.

Knee brace (or prop)

Knee height

The distance between the ground and the top of the wall.
