Shed Builder App Australia: Design Council‑Ready Colorbond Steel Sheds Online
If you’re weighing up a custom-built double garage in Perth, a farm machinery shed in regional NSW, or a cyclone-rated carport in coastal QLD, the right shed builder app saves weeks of back-and-forth. This guide shows you how to design a compliant, durable, and great‑looking steel shed with industry‑accurate specs for Australian conditions.
Why use a shed builder app for Australian conditions?
- Draw accurate shed plans (skillion, gable, American barn) with live pricing
- Choose Colorbond or Zincalume cladding and see a cost/benefit breakdown
- Auto-calculate site-specific wind rating (Regions A–D) and terrain categories
- Produce council-ready drawings, slab notes, and engineering calculations
- Compare DIY shed kits vs custom, add options like insulation and vermin flashing
- Get delivery timelines and installer availability in your postcode
What Are the Best Shed Materials for Perth’s Climate?
Perth’s hot summers, coastal air and UV exposure push roofing and walling hard. Most premium steel sheds use either Colorbond or Zincalume. Here’s how they stack up for WA:
Colorbond vs Zincalume — Which Is Better for WA Conditions?
| Feature | Colorbond Steel | Zincalume Steel |
|---|---|---|
| Coating & finish | Pre-painted, multiple layers with baked-on colour | Aluminium/zinc alloy coating (silvery finish) |
| Heat reflectivity (light colours) | Excellent with lighter Colorbond tones | Very good (unpainted light finish) |
| Coastal corrosion resistance | Strong; consider Ultra grades in severe marine zones | Good; additional protection recommended near surf coasts |
| Aesthetics for residential streetscapes | Wide Aussie palette, matches gutters/doors | Industrial look; can be painted later |
| Cost | Higher | Lower |
| Best fit for Perth | Premium homes and custom Colorbond garages | Budget-friendly rural or workshop builds |
In Perth and coastal WA, light Colorbond roofs help reduce heat load and resist UV, while Zincalume remains a value option for workshops set back from the surf. The shed builder app includes a Colorbond vs Zincalume comparison with price and performance notes.

- Site plan tools: setbacks, easements, and driveway tie‑in for a council-ready layout
- AR preview: place your shed at scale in your backyard with a smartphone
- Export: council submission pack (drawings, specs), installer brief, and maintenance guide
Local compliance: council approvals and wind ratings across Australia
Australian sheds must comply with the National Construction Code (NCC 2022) and relevant AS/NZS standards. The shed building app assembles documents councils expect and aligns with local wind, terrain and corrosion environments.
How to Get Council Approval for Your Custom Shed in WA
- Check zoning and overlays: Your council’s R‑Codes and local planning policies set setbacks and heights.
- Confirm wind region: Perth is generally Region A (non‑cyclonic), while the Pilbara/Gascoyne includes Region D (cyclonic). The app applies AS/NZS 1170.2 and terrain categories for accurate pressures. Added 2024 WA wind-rating compliance notes
- Generate drawings: site plan, floor plan, elevations, footing/slab notes, connection details.
- Submit BA/DA: Lodge building permit with engineering certificate (RPEQ/RPEng as required), energy notes if specified, and owner‑builder/licensed builder details.
- Book inspections: footing, slab, and final as required by your permit authority.
Need council-approved sheds WA? The app’s pack aligns with typical WA council checklists and includes materials specs for coastal corrosion categories.
Cyclone-rated sheds in QLD
For North QLD and coastal belts, you’ll need wind-rated sheds for cyclonic areas (Regions C/D). The app upgrades portal frames, connections and sheeting fasteners, and can specify windlock roller doors and extra hold‑downs for cyclone-rated sheds QLD.
BAL and rural approvals in NSW and VIC
For rural sheds NSW or sheds on vegetated fringes in VIC, include BAL construction notes, ember protection, and non‑combustible claddings. The app’s BAL module helps you select compliant options without over‑specifying.

5-Step Buying Guide for Custom Sheds in Australia
- Define the use: car storage, workshop, farm machinery, or mixed use with a mezzanine.
- Pick size and roof: e.g., 6×6 m custom-built double garage, gable vs skillion for height/setback limits.
- Select materials: run a Colorbond vs Zincalume comparison for cost, look, and corrosion zone.
- Engineer and price: use the app’s build price estimator; add insulation, doors, ventilation.
- Approval and build: generate the council pack, book slab and installer, and plan maintenance.

FAQ: shed builder app, engineering and approvals
Does the shed builder app handle DIY and installed options?
Yes. You can price DIY shed kits with delivery, or add professional installation. The app shows installer lead times in your area.
How accurate is the wind rating?
The app calculates pressures using AS/NZS 1170.2 with your wind region (A–D), terrain category and shielding. An engineer reviews atypical or high‑risk sites before certification.
Can I use Colorbond near the coast?
Yes, but in severe marine zones select appropriate grades/flashings and follow maintenance schedules. Consider Ultra grades and additional coatings for coastal corrosion protection.
How long do council approvals take?
Most residential sheds are fast‑tracked when the pack is complete. Timelines vary by council and whether planning is also required.
Do I need a slab first?
Not always. Many rural sheds use piers first and slab later. The app includes shed slab engineering notes if you’re pouring at build time.
DIY kit vs custom-built: which suits you?
| Option | Pros | Considerations |
|---|---|---|
| DIY shed kits | Lower cost; flexible timing; great for straight‑forward sites | Requires tools/skills; organise slab and inspections yourself |
| Custom-built | Turn‑key; faster approvals; complex sites handled by pros | Higher cost; book early in peak seasons |
