Two Door Shed: The Australian Guide to Double Door Sheds (2025)
Whether you call it a two door shed, 2 door storage shed, or a double door shed, the goal is the same: a robust, secure, council-compliant Colorbond steel shed that stands up to Australian conditions—and makes daily access easy. This guide brings together industry know‑how, local standards, and practical buying steps for Australian homeowners, renovators, and property investors.
Who is this guide for?
- Homeowners needing easy access storage for bikes, mowers, and tools
- Tradies and renovators wanting a workshop-friendly, double-door opening
- Investors improving rental yield with low-maintenance backyard storage
- Regional and coastal buyers needing wind-rated, corrosion-resistant solutions
What do top competitors cover—and what’s missing?
We reviewed the top Australian results for “two door shed.” Big shed brands and retailers highlight:
- Australian-made steel, 20–30 year warranties
- Double doors or twin access openings for wide gear
- Delivery Australia-wide, DIY shed kits, and simple assembly
- Roof options: skillion and gable, Colorbond colours, padlocks
Where they fall short:
- Limited local detail on wind ratings for WA/QLD and site-specific engineering
- Minimal guidance on council approvals and footing design
- Thin coverage of condensation control, bushfire BAL, and coastal corrosion
What you’ll get here:
- Added 2024 WA wind-rating compliance notes and council approval tips
- Practical details for council-approved sheds WA, cyclone-rated sheds QLD, and custom Colorbond garages Perth
- Material comparisons (Colorbond vs Zincalume), cyclonic tie-downs, and corrosion categories
Why choose a two door shed?
- Wider clear opening for mowers, wheelbarrows, and workbenches
- Better airflow and natural light with optional glass inserts
- Flexible access: front and side double doors to split storage/work zones
- Easy add-ons: vermin flashing kits, shelving, solar-ready roof, rainwater harvesting
What are the best shed materials for Perth’s climate?
In WA, heat, UV, and ocean-borne salts drive material choice. Most quality two door sheds use Australian steel with either Zincalume or Colorbond finish.
Colorbond vs Zincalume — Which is better for WA conditions?
| Feature | Colorbond steel | Zincalume steel |
|---|---|---|
| Finish | Pre-painted baked-on paint system | Aluminium-zinc alloy coating (no paint) |
| Heat/UV performance | Excellent; lighter colours reduce heat gain | Good reflectivity but can glare |
| Coastal resistance | Strong, but maintain and rinse near coast | Good, but more frequent maintenance near surf |
| Aesthetics | Wide colour range to match homes | Industrial silver-grey look |
| Cost | Typically higher | Usually more affordable |
| Best for | Residential backyards, premium finish | Budget-friendly, rural/utilitarian |
Do you need a wind-rated two door shed?
Yes. Wind rating is critical for compliance and safety, especially in coastal WA and cyclonic QLD. Look for ShedSafe-accredited designs engineered to AS/NZS 1170.2 for your site wind speed, terrain, and shielding.
- Non-cyclonic regions: N1–N3 (typical suburban sites)
- Cyclonic regions: C1–C4 (tropical QLD, northern WA)
Added 2024 WA wind-rating compliance notes: In WA, ensure your engineer certifies to AS/NZS 1170.2 with site wind region (A–D), terrain category, and topography multipliers. Many Perth metro blocks are Region A (N ratings), while coastal and northern WA sites can trigger higher pressures and extra tie-downs.
How to get council approval for your custom shed in WA
Step-by-step approval pathway
- Check local planning rules: setbacks, height, site coverage
- Obtain engineered drawings and wind rating (AS/NZS 1170.2)
- Prepare slab/footing details and site plan
- Lodge Building Permit (BA2) or certified application (BA1) with your local council
- Install per drawings; book any required inspections
Helpful resources: WA Planning and council portals often outline shed sizes permitted without planning approval but still needing a Building Permit. When in doubt, call your local council building team.
Popular double door shed types and use-cases
- Urban garden shed (Perth, Melbourne, Sydney): 3.0 × 2.25 m, double hinged doors
- Workshop shed (Brisbane, Adelaide): 3.0 × 3.0 m, double doors plus window and whirlybird
- Rural sheds NSW: 6.0 × 3.0 m with sliding double doors for ride-on and farm machinery storage
- Custom Colorbond garages Perth: twin swing doors or a double roller with a side double door
- Coastal storage (Bunbury, Geraldton): Colorbond with marine maintenance schedule
Which double door type suits your site?
- Hinged double doors: simple, cost-effective, great for smaller spans
- Sliding double doors: space-saving, ideal for wider openings (rural and workshop sheds)
- Dual roller doors: best for garages; consider motorisation for daily use
Add security and longevity with galvanised frames, anti-pry hasps, powder-coated hinges, and stainless fasteners near the coast.
Skillion vs gable roof for two door sheds
| Roof type | Pros | Considerations |
|---|---|---|
| Skillion | Modern look, easier to place near a fence, simple drainage | Lower volume; orient fall away from neighbours |
| Gable | Classic look, extra headroom, better airflow | Slightly more complex install; higher ridge line |
How to manage heat and condensation
- Use anti-condensation blanket or insulated roof panels
- Include vents, whirlybirds, or louvre windows; cross-ventilation reduces corrosion risk
- Install thermal breaks under roof sheets in hot zones
Pro tip: Did you know using insulated roof panels can reduce internal shed temperatures by up to 10°C in summer?
Do double door sheds need bushfire (BAL) compliance?
In bushfire-prone areas, sheds may require BAL measures (BAL–12.5 to BAL–40/Flame Zone) under the NCC and local planning overlays. This can affect door materials, ember sealing, and gutter guards.
Buying near the coast? Combat corrosion
Within about 1 km of breaking surf, use Colorbond or enhanced coatings, rinse monthly, specify stainless screws, and consider hot-dip galvanised frames. Ask for the corrosion category (AS 4312/ISO 9223) in your quote.

5-Step Buying Guide for Custom Sheds in Australia
- Scope your use: tools, bikes, benchtop, clearance for double doors
- Choose material: Colorbond vs Zincalume based on aesthetics and coastal proximity
- Engineer for wind: N/C class to AS/NZS 1170.2; confirm tie-downs and door wind-locks
- Plan the base: slab thickness, drainage, termite management, stormwater connection
- Approval and install: lodge permits, book electrician/lighting, add vents and security
DIY shed kit vs custom-built: Which suits you?
| Option | Pros | Best for |
|---|---|---|
| DIY shed kits | Lower cost, quick delivery, simple sizes, weekend install | Garden storage, budget builds, non-cyclonic sites |
| Custom-built | Engineered to site, bigger spans, door flexibility, higher wind classes | Workshops, garages, coastal/cyclonic areas, value-add to property |
FAQs: Two door sheds in Australia
What size double door opening is typical?
Common hinged double doors range 1.5–2.4 m wide. Sliding double doors can exceed 3.0 m for wider equipment. Confirm clear opening after hardware.
Do I need council approval?
Many councils require a Building Permit for sheds above small exempt sizes or near boundaries. In WA, even compliant small sheds may still need a Building Permit. Always check your LGA.
What slab do I need?
Typical slabs are 100–125 mm concrete with SL72/SL82 mesh on compacted base, with edge thickenings in higher wind zones. Chemical or cast-in anchors per engineering.
Are Colorbond colours energy-efficient?
Lighter Colorbond colours reflect heat better. Pair with roof insulation for comfort if you plan to work inside.
How long does installation take?
DIY garden sheds: 4–8 hours for two people. Custom workshops/garages: 1–3 days after slab cure, depending on size and weather.
What about warranties?
Reputable brands offer 20–30 year warranties on cladding coatings and structural warranties on frames. Follow maintenance guidelines, especially near the coast.

Ready to design your two door shed?
Ask for a site-specific, wind-rated design, confirm council requirements, and compare Colorbond vs Zincalume based on your location. If you’re in WA, ensure your quote notes Region, Terrain Category, and tie-down schedule. In QLD, request cyclone-specific detailing for doors and cladding.
