Audience: Australian homeowners, renovators, and property investors who want premium-quality sheds at sharp prices.
Pro tip: Did you know using insulated roof panels can reduce internal shed temperatures by up to 10°C in summer? This is a small upgrade that pays back in comfort and energy savings. See guidance from Energy.gov.au on insulation.
“Cheap” Garden Sheds in Adelaide Doesn’t Mean Flimsy — Here’s How to Buy Smart
The goal is value, not the lowest sticker price. Focus on the steel grade, roof design, corrosion protection, wind rating, and a compliant slab. A well-specified Colorbond steel shed can be affordable and last decades in Adelaide’s dry, warm summers and occasional coastal air flows.
- Choose Bluescope Colorbond or Zincalume cladding with proper thickness (typically 0.35–0.42 mm for domestic sheds).
- Confirm the shed kit is engineered for Adelaide’s Wind Region A (AS/NZS 1170.2), usually N2 or N3 depending on site exposure.
- Opt for hot-dip galvanised or zinc-coated frame members compliant with AS/NZS 4600 (cold-formed steel structures).
- Use a slab to AS 2870 and fixings to AS 5216 with cyclone ties or extra bracing in exposed sites even in non-cyclonic zones.
What Are the Best Shed Materials for Adelaide’s Climate?
Adelaide’s Mediterranean climate, sea breezes off Gulf St Vincent, and occasional dust or salt-laden winds mean you want strong corrosion resistance and good thermal performance.
Colorbond vs Zincalume — Which Is Better for WA Conditions?
Although this comparison is framed for WA, the same principles apply in SA. For Adelaide suburbs within 1–5 km of the coast, a Colorbond topcoat and correct corrosion category detailing are wise. For inland suburbs, Zincalume can be great value.
| Feature | Colorbond | Zincalume |
|---|---|---|
| Corrosion resistance | Excellent with paint barrier; good for coastal-suburban Adelaide | Excellent base coat but needs care near marine influences |
| Heat reflectivity | High with light colours (e.g., Surfmist); reduces heat gain | High reflectivity in bare metallic finish |
| Aesthetics | Large Colorbond colour range to match SA homes | Metallic silver-grey; paint later if desired |
| Cost | Higher upfront | Usually cheaper |
| Warranty and longevity | Strong warranties when installed to spec | Strong warranties when installed to spec |
| Best use | Urban/coastal Adelaide, premium look | Budget-friendly inland/rural sites |
Also consider:
- Frame: Galvanised steel purlins and girts for termite-proof durability.
- Roof insulation: Anticon blanket or insulated panels to limit summer heat and condensation.
- Fixings: Class 4 fasteners near coast; comply with AS/NZS 2312.2 for corrosion protection systems.
How Much Do Cheap Garden Sheds Cost in Adelaide in 2025?
Indicative price ranges based on current materials trends and industry reports including the 2025 Australian Steel Market Outlook and the 2025 HIA Outdoor Structures and Home Improvement Report:
- Compact DIY garden sheds (1.5 × 1.5 m to 3 × 2.3 m): $350–$1,200 for Zincalume; $550–$1,600 for Colorbond.
- Mid-size garden/workshop sheds (3 × 3 m to 3 × 4.5 m): $900–$2,400 kit-only; add $1,000–$2,500 for slab and fixings.
- Large backyard sheds (3 × 6 m+): $2,200–$5,500 kit; $4,500–$9,500 installed with slab (site dependent).
- Concrete slab: Typically $120–$180 per m² in metro Adelaide for standard shed slabs (thickness to AS 2870 and engineering spec).
Expect higher costs for premium colours, windows, roller doors, insulation, or N3 wind design in exposed, hill-face, or coastal fringe sites.
Do You Need Council Approval for Garden Sheds in Adelaide?
In South Australia, approvals are processed via the PlanSA system under the Planning, Development and Infrastructure Act 2016. Many small sheds are exempt or “accepted” development if they meet size, height, boundary, and stormwater rules. Always confirm with your local council or accredited certifier.
How to Get Council Approval for Your Custom Shed in SA
- Check whether your shed falls under “accepted development” on PlanSA.
- Get engineered drawings: site plan, slab to AS 2870, fixings to AS 5216, wind rating to AS/NZS 1170.2.
- Lodge application via PlanSA (planning and building consent) if required.
- Comply with the NCC (2022) and relevant Australian Standards (AS/NZS 4600, AS 4100, AS 1562.1 for roofing installation).
- Arrange inspections where required; keep your approval documents for insurance.
Added 2024 SA wind-rating compliance notes Ensure you declare shielding, terrain category, and topography in your engineering calcs. Misstating these can invalidate approvals or warranties.
Flat, Gable, or Skillion Roof — What’s Best for Adelaide?
| Roof Type | Pros | Cons | Best For |
|---|---|---|---|
| Flat | Lowest cost, simple to build, tidy lines | Lower headroom; needs good drainage to avoid ponding | Small backyard storage in sheltered suburbs |
| Gable | Classic look, good airflow, strong under wind | Slightly higher cost and height | Workshops, garages, better performance in exposed sites |
| Skillion | Modern look, easy water run-off, solar-friendly pitch | Wind uplift needs correct fixings and edge detailing | Narrow lots, modern homes, easy guttering to rainwater tanks |
DIY Shed Kits vs Custom-Built vs Second-Hand in Adelaide
| Option | Pros | Cons | Who It Suits |
|---|---|---|---|
| DIY Shed Kits | Cheapest, fast delivery, easy sizes, weekend build | Limited customisation; you handle slab, drainage, and compliance | Handy owners wanting budget “garden sheds Adelaide” options |
| Custom-Built | Tailored size, doors, windows, mezzanine storage, workshop power | Higher cost; approval process may take longer | Workshops, home offices, “custom Colorbond garages Perth/Adelaide” level finish |
| Second-Hand Sheds | Lowest upfront price, quick pickup | Hidden corrosion, missing parts, no engineering, re-approval required | Budget buyers able to refurbish, not time-sensitive |
Second hand sheds for sale Adelaide — What to check
- Ask for original engineering/brand and the wind rating. If none, factor in re-engineering costs.
- Inspect for red rust at sheet edges, base rails, and fastener lines. Replace any Class 3 screws with Class 4 near the coast.
- Measure twice; older kits may not meet current NCC or AS/NZS 1170.2 N-grade requirements.
- Budget for new anchors, flashing, and guttering to suit your site’s stormwater plan.

5-Step Buying Guide for Custom Sheds in Australia
- Measure your site: Check setbacks, easements, and overheads. Sketch door clearances and vehicle turning if it’s a garage.
- Pick materials: Colorbond for coastal/urban Adelaide aesthetics; Zincalume for inland savings. Add insulation for comfort.
- Engineer the wind rating: Most Adelaide = N2; exposed = N3. Get calcs to AS/NZS 1170.2; frame to AS/NZS 4600.
- Plan approvals: Confirm exempt vs accepted vs performance assessment on PlanSA. Prepare site plan, engineering, and stormwater.
- Select your installer: Compare itemised quotes including slab, fixings, gutters, delivery, and lead times. Verify insurances via HIA or Master Builders.
FAQs — Cheap Garden Sheds Adelaide
Will a shed rust near the coast?
Use Colorbond with appropriate corrosion category detailing and Class 4 fasteners. Keep at least 1 km from breaking surf for standard warranties, or follow marine detailing guidelines. Clean salt spray periodically. See Australian Steel Institute guidance.
Do I need a slab or can I use pavers?
Small sheds can sit on pavers or a rebated perimeter beam if allowed by engineering. For workshops or larger sheds, a reinforced concrete slab to AS 2870 is recommended for strength, durability, and moisture control.
What about bushfire (BAL) ratings?
Some Adelaide Hills sites may need a BAL. Metal cladding helps. Confirm siting, ember protection, and gutter guards if required. Obtain a BAL assessment as part of planning.
Are steel sheds termite-proof?
Galvanised steel frames are termite-proof. Keep timber benches or stored goods off the ground and maintain site drainage.
Do you deliver to outer suburbs?
Most suppliers deliver across metro Adelaide and regional SA. Check fees and lead times, especially during peak building seasons.
