How Does Terrain Affect my Garage or Shed?

Home / Blog / How Does Terrain Affect my Garage or Shed?

The terrain that your property rests on can significantly impact your shed's design, stability, and even safety, so it's essential to seek expert advice before commencing any DIY projects.

To install a garage or shed on steep, hilly, or high-wind terrain, look at our insider tips below before getting to work.

Know Your Terrain Category

Terrain categories are used to measure the wind-breaking effect of an area based on the buildings, trees, and other obstructions. The more wind obstructions around your shed, the higher the terrain category.

The categories range from Category 1, with "exposed open terrain with few or no obstructions", to Category 4, which includes "terrain with numerous large, high, and closely spaced obstructions, such as large city centres.".

If you're building in a suburban area, your shed will likely be constructed on Category 3 terrain. Any good shed provider can assist you in choosing suitable materials and positions and overcoming installation difficulties associated with your wind region. If you're unsure of your category, contact your local council.

Choose the Right Materials for Your Terrain

Steel is the most popular (and arguably the most sensible) design choice for free-standing sheds and garages in Adelaide. In most cases, the use of BlueScope steel is recommended for steep or windy blocks, as its light, sturdy, and durable characteristics make it ideal for withstanding high winds and prevent it from sinking, sliding, or dipping from its weight, which can be a risk with heavier materials.

However, other materials may be more suitable depending on the shed's usage requirements. Talk to your shed supplier to determine if BlueScope Steel suits your usage requirements and the surrounding terrain.

For garages and sheds being built on steep or windy blocks, garage roller doors are usually the most practical and convenient door option. Compared to other door types, like hinged doors, which risk becoming stuck on upward slopes, garage roller doors are easier to manage. In some projects, different door types will work best, in which case your supplier can make a recommendation.

Don't Try to DIY

Trying it on a garage or shed can be very unsafe if you're not professionally qualified to build structures on a sloped block. This space must always be safe to enter, so it's best to call in the experts. The potential impact of a DIY installation is that your shed could be rickety, unsuitable for your wind region, and dangerous to your family and neighbours during a storm. Don't leave it to chance—call a licenced contractor to be sure the installation runs smoothly and the structure is safe.
