Garden Sheds Perth WA | Custom Colorbond Steel Sheds, Garages & Workshops
What Are the Best Shed Materials for Perth’s Climate?
Perth summers are hot, dry and often windy; coastal suburbs face salt-laden air. That’s why most shed buyers choose Colorbond or Zincalume steel cladding with hot-dip galvanised frames and cyclone-tested fasteners. Below is a quick comparison for WA conditions.
| Feature | Colorbond (painted, pre-finished) | Zincalume (aluminium/zinc coated) |
|---|---|---|
| Coastal corrosion resistance | Excellent in suburban/coastal zones; choose Ultra for marine | Very good; keep clear distances from splash zones |
| Heat performance | Cooler with lighter colours and high solar reflectance | Reflective but can glare; may heat up visually |
| Aesthetics | Wide colour palette to match WA homes and fences | Classic metallic; paintable later |
| Cost | $$ (mid–high) | $ (budget–mid) |
| Warranty | Up to 20–36 years (application dependent) | Up to 20–36 years (application dependent) |
| Best for | Garden sheds Perth, custom Colorbond garages Perth, premium installs | DIY shed kits, rural sheds |
For most garden sheds Perth WA homeowners, Colorbond walls plus a lighter-colour roof gives the best blend of cooling and street appeal. Near the coast, consider Colorbond Ultra and stainless fasteners.
Which Shed Types Do Perth Homeowners Buy Most?
Garden Sheds (Small to Medium)
Popular sizes: 2.3×1.5 m to 3×3 m. Ideal for gardening gear, bikes and small tools. Options include single or double hinged doors, sliding doors for tight side setbacks, and skylight panels for daylight.
Workshop Sheds Perth
Common sizes: 6×4 m, 7×5 m, 9×6 m. Add 2.7–3.0 m eave height, ventilators, insulation and a 100 mm reinforced slab. Suits hobbyists, tradies and small machinery storage.
Garage Sheds Perth
Single, double and triple-bay garages with roller doors, motorised openers and wind-rated frames. Popular double: 6×6 m. Integrate a personal access (PA) door and window kits.
Custom Sheds Perth
Non-standard footprints, odd blocks, and architectural cladding. Think skillion roofs to meet boundary heights, or gable roofs to match the house. We handle council-approved sheds WA and site-specific engineering.
Small Sheds Perth
When space is tight, we use sliding doors and 1.5 m modules. Compact small garden sheds Perth WA can often meet exempt development rules, depending on council.
Storage Sheds & Rural Options
From secure storage shed Perth solutions to rural machinery bays. We also design wind-rated sheds for cyclonic areas when shipping to North-West WA or interstate (e.g., cyclone-rated sheds QLD).
How to Choose Size, Wind Rating and Roof Style
- Wind region: Greater Perth is generally non-cyclonic (Region A). Most suburban blocks suit N2 or N3 depending on terrain and shielding.
- Importance level: IL1 (garden/storage), IL2 (garages/workshops) affects design loads.
- Frame and fixings: Specify engineer-certified portal frame spacing, hold-down bolts, and roof screw patterns per AS 4100/4600 and AS/NZS 1170.
Roof Style: Gable vs Skillion vs Flat
- Gable: Classic look, great drainage, extra headroom in centre.
- Skillion (monoslope): Modern style; maximises boundary compliance and solar panel angle.
- Flat: Lowest profile and budget-friendly; ensure compliant fall and gutters.
Door choices: wind-rated roller doors, wide sliding doors for workshop sheds Perth, or double hinged for garden access. Ask for wind-lock rollers where exposure is high.
How to Get Council Approval for Your Custom Shed in WA
Planning and Building — The Practical Steps
- Check R-Codes and local policy: Setbacks, wall height, site coverage and streetscape rules vary by council.
- Prepare a site plan: Show boundaries, existing structures, stormwater, sewer and easements.
- Engineering & certification: Obtain site-specific drawings and calculations. In WA, a private building surveyor can issue a Certificate of Design Compliance (CDC).
- Apply for Building Permit: Certified (BA1 with CDC) or uncertified (BA2) to your local council. Typical decision times are up to 10 business days after a complete certified submission.
- Construct & finalise: Build per the permit and engineer’s details; keep invoices and warranties.
Tip: Many councils exempt very small sheds (often under 10 m² and under 2.4 m high), but planning rules and boundary clearances still apply. Always confirm local requirements before you buy. See WA guidance on building approvals at the Department of Mines, Industry Regulation and Safety (DMIRS) website building approvals.

FAQs — Garden Sheds Perth WA
Do I need a permit for a small garden shed?
Often exempt under a size/height threshold (commonly 10 m² and 2.4 m high), but rules vary. Planning and boundary setbacks still apply. Check your local council or a building surveyor.
What slab do I need?
Typical: 100 mm reinforced concrete with SL72 mesh and thickened edges for larger garages. Small sheds can use piers or a paved base with engineered anchors.
How long does delivery take?
DIY kits: 2–4 weeks. Installed projects: 4–10 weeks depending on permits, slab cure, and crew availability.
Are your sheds wind-rated?
Yes. All sheds are engineered to AS/NZS 1170.2 for your site’s wind region and terrain. We also supply wind-rated sheds for cyclonic areas when required.
What about insulation?
Foil-backed blanket or insulated roof panels help with heat and condensation. See Energy.gov.au’s advice on reflective insulation insulation guidance.
Do you ship to regional WA?
Yes. We deliver to most of WA and can provide install partners in major centres. For coastal or industrial zones, we’ll specify upgraded coatings and fixings.
Technical Notes and Standards
- Structural design to AS/NZS 1170 series; steel to AS 4100/4600; cold-formed framing to AS/NZS 4600.
- NCC 2022 compliance including condensation management and thermal breaks where required.
- Fasteners and flashings selected for corrosion zones per manufacturer guidance and CSIRO notes.

Pro Tip
Did you know? Using insulated roof panels or R1.3–R2.5 roof blanket can reduce internal shed temperatures by up to 10°C in summer, especially with light-colour Colorbond roofs and ridge ventilation.
