What Does a Professional Garden Shed Installation Include?
Reputable garden shed fitters and storage shed installers typically offer the following end-to-end service (often called “shed and installation” or a garden shed assembly service):
- Site assessment: Access, setbacks, easements, wind region, and bushfire (BAL) checks
- Base works: Concrete slab, piers or footings, engineered anchors
- Shed assembly: Frames, cladding (Colorbond or Zincalume), doors, windows, vents
- Compliance: Engineering, wind rating certification, tie-down details, and council paperwork
- Finish: Flashings, gutters, downpipes, sealants, and stormwater connection (where required)
How Much Does Garden Shed Installation Cost in Australia (2025)?
Garden shed installation cost varies by size, base type, wind rating, and access. Typical ranges (AUD, GST inc):
- Small kit (e.g., 2.3 × 2.3 m) assembly only: $350–$900
- Medium kit (e.g., 3 × 3 m) assembly: $700–$1,500
- Large kit (e.g., 3 × 6 m) assembly: $1,400–$3,000
- Concrete slab (typical 100 mm with mesh): $110–$180/m² incl. formwork. Example: 3 × 3 m slab $990–$1,620
- Engineered footing upgrades (wind/cyclone/coastal): +$500–$2,000
- Council/Private Certifier fees (if needed): $0–$1,800+, state and complexity dependent
- Electrical, insulation, shelving, roller doors: priced on add‑ons
Tip: Ask for a line‑item quote covering slab, anchors, engineering, and accessories to compare “apples with apples.”
What Are the Best Shed Materials for Perth’s Climate?
Perth’s hot summers, coastal salinity, and afternoon sea breeze demand heat-reflective colours, corrosion resistance, and robust anchorage. Here’s a quick Colorbond vs Zincalume comparison for WA and broader Australia.
| Feature | Colorbond (pre-painted steel) | Zincalume (aluminium-zinc alloy) |
|---|---|---|
| Heat Performance | Light colours (e.g., Surfmist) reflect heat; good for Perth | Reflective bare metal; can be hotter inside without insulation |
| Corrosion Resistance | Excellent in most environments; select for C3–C4 coastal zones | Very good; may show patina near coastlines if unwashed |
| Aesthetics | Wide colour range (Monument, Woodland Grey, etc.) | Industrial, metallic look only |
| Maintenance | Low; wash down near marine exposure | Low; rinse more frequently in marine zones |
| Cost | Usually 5–15% higher | Budget-friendly |
| Use Case | Premium garden sheds, custom Colorbond garages Perth, residential installs | Rural sheds NSW, farm machinery storage, cost-driven builds |

Which Roof Style Is Right for Your Site?
| Roof Type | Pros | Considerations | Best For |
|---|---|---|---|
| Gable | Classic look, good drainage, easy guttering | Taller ridgeline may trigger height limits | Garden shed assembly in suburban blocks |
| Skillion (Mono) | Sleek, modern, simple structure | Watch prevailing wind direction and eaves height | Side setback areas, narrow blocks |
| Flat | Low profile, often exempt easier | Must ensure fall; can run hotter | Low-visibility storage shed installers projects |
How Do I Choose the Right Wind Rating and Anchoring?
Wind rating is mandatory. Your shed’s engineering must match your site’s wind region and terrain category per AS/NZS 1170.2. In northern WA/QLD, “cyclone-rated sheds” are essential.
- Regions A/B: Non-cyclonic (most of southern Australia)
- Regions C/D: Cyclonic (coastal QLD, NT, northern WA)
- Typical ratings: N2–N3 (non-cyclonic), C2–C3 (cyclonic)
Added 2024 WA wind-rating compliance notes: Many councils now request wind region confirmation and site classification on drawings for council-approved sheds WA. Ensure your supplier provides engineering for your exact address, including footing details and anchor schedules.
How Do I Get Council Approval for a Custom Shed?
How to Get Council Approval for Your Custom Shed in WA
- Check local planning rules (R-Codes) for setbacks, open space, and height
- Building Permit may be required unless minor and exempt in your LGA
- Submit certified plans (engineer-signed), site plan, and specifications
Victoria (VIC)
- Many small sheds (typically up to 10 m²) can be exempt from a building permit if they meet height and setback rules (see Building Regulations 2018)
- Larger or boundary-hugging structures need a Building Permit via a Private or Municipal Building Surveyor
New South Wales (NSW)
- Exempt Development for many sheds up to 20 m² if height/setback and lot rules are met
- Otherwise, use a Complying Development Certificate (CDC) or DA
Queensland (QLD)
- Some are accepted development (self-assessable) under local planning
- Cyclone-rated sheds QLD must meet C-region engineering and anchorage
Lean on your shed builder or a Private Certifier to fast‑track approvals for council-approved sheds WA, VIC, NSW, and QLD.
DIY Shed Kits or Professional Shed and Installation?
| Option | Pros | Watch Outs | Best For |
|---|---|---|---|
| DIY shed kits | Cheapest upfront, flexible timing | Incorrect anchoring voids warranty; time-consuming | Handy owners, simple non-cyclonic sites |
| Professional shed assembly service | Faster, compliant, warranty support | Higher cost | Coastal, cyclonic, rental/investment properties |
