6×6 shed price breakdown

  • Steel kit (framing to AS/NZS 4600, cladding to AS 1397): 45–60% of total
  • Doors and windows (double roller doors, personal access door, glass): 10–20%
  • Engineering and certifications (site-specific): 3–6%
  • Concrete slab and footings: 15–25%
  • Erection/labour and plant: 15–25%
  • Council/Certifier fees (state and local): $300–$2,000+
  • Upgrades (sarking, insulation, whirlybirds, vermin seals, gutters, electrical): as specified
Pro tip: Did you know using insulated roof panels can reduce internal shed temperatures by up to 10°C in summer? In Perth and inland WA, pairing insulation with ridge vents or whirlybirds dramatically improves comfort.

What Are the Best Shed Materials for Perth’s Climate?

For coastal and high-UV environments, most homeowners opt for Colorbond steel. Zincalume is economical, but Colorbond (and Colorbond Ultra in severe marine zones) offers better corrosion resistance and thermal performance.

Colorbond vs Zincalume — Which Is Better for WA Conditions?
Feature Colorbond (incl. Ultra/Matte) Zincalume
Corrosion resistance (coastal) High; Ultra recommended within ~200–400 m of surf Moderate; not ideal in sea-spray zones
Heat reflectivity Thermally efficient colours reduce heat gain Reflective when new; dulls over time
Colour range Extensive COLORBOND palette Metallic finish only
Typical kit price ~10–20% higher than Zincalume Lowest upfront cost
Warranty Up to 20–36 years (conditions apply) Up to 20–25 years (conditions apply)
Best for Perth metro, coastal WA, premium finish Budget builds inland, DIY shed kits

For detailed steel guidance, see the Australian Steel Institute and manufacturer data (warranties vary by distance to coast and environment). Always request the exact steel grade and coating class in your quote.

Customising a 6×6 shed: garage, workshop, or garden shed?

A 6×6 shed can be configured as a double garage, workshop, or robust 6×6 storage shed. Popular inclusions for custom Colorbond garages Perth and steel sheds Perth:

  • Dooring: two 2.4–3.0 m roller doors (manual or motorised), 1x PA door
  • Roof: gable (22.5° for looks/loft) or skillion (2–5° for modern look)
  • Wall height: 2.4 m standard; 2.7–3.0 m for 4WDs and racking
  • Windows: 2–4 fixed or sliding with flyscreens
  • Insulation: roof blanket or insulated panels; add sarking under roof
  • Vermin flashing, gutter guard (handy in BAL areas)
  • Electrical: LED batten lights, GPOs, 15A outlet for welders

Roof options at a glance

  • Gable roof: classic look, better heat purge with ridge vent; marginally higher cost
  • Skillion roof: modern profile, simpler install, good for side-by-side solar
  • Flat roof carports: best for affordable carports for Australian homes but less headroom

Compliance, wind ratings, and council approval in Australia

Ensure your shed supplier provides site-specific engineering to AS/NZS 1170.2 (wind loads), AS/NZS 4600 (cold-formed steel), AS 4100 (steel structures), and designs consistent with the NCC 2022. Cyclonic designs (Regions C/D) require higher-grade fixings, additional bracing, and door wind-locks.

Added 2024 WA wind-rating compliance notes Most Perth metro sites are Region A (N2–N3), but coastal and escarpment locations can increase pressures. Confirm terrain category, topography multiplier, and shielding. For marine zones, consider Colorbond Ultra, stainless screws to AS 3566 Class 4, and enhanced gutter fall.

How to Get Council Approval for Your Custom Shed in WA

  1. Check zoning and R-Codes setbacks (front/side boundaries, site coverage).
  2. Order site plan, elevations, slab detail, and structural certificate from your shed engineer.
  3. Lodge BA2/DA as required with local council or a private certifier; allow 10–25 business days.
  4. Book Dial Before You Dig and soil test if slab/footings are included.
  5. Final inspection/compliance certificate after erection.

For council-approved sheds WA or cyclone-rated sheds QLD, choose suppliers experienced with local codes and wind regions. In NSW/VIC bushfire areas, verify BAL compliance (embers, sarking, mesh, and non-combustible cladding).

  • Pros: lowest 6×6 shed kit price, flexible timing, great for experienced tradies
  • Cons: you manage slab, permits, cranes/scissor lift, and insurances; safety risk

Turnkey custom-built

  • Pros: single point of accountability, faster timeline, council handled, warranty coverage
  • Cons: higher upfront cost, lead times during peak seasons

5-Step Buying Guide for Custom Sheds in Australia

  2. Site factors: Wind region, BAL, soil class, drainage, access for slab and erection.
  3. Material choice: Do a Colorbond vs Zincalume comparison; consider Colorbond Ultra near coast.
  4. Quotes: Get 2–3 like-for-like quotes with engineering, door specs, insulation, and fixings listed.
  5. Approvals & build: Confirm council pathway, engineering certificates, slab tolerances, and practical completion checklist.

Frequently asked questions

What is the difference between a 6×6 garden shed and a 6×6 garage?

A garden shed is light-duty (often thin-gauge panels, limited wind resistance). A 6×6 garage uses engineered steel frames, rated roller doors, and compliant fixings to house vehicles and withstand design winds.

How thick should my slab be for a 6mx6m shed?

Commonly 100–120 mm with 25–32 MPa concrete and SL72 mesh, thickened edge beams or piers as engineered, especially in reactive clay or cyclonic zones.

How long does a 6×6 shed take to build?

Lead time 2–6 weeks for engineering and supply; 1–3 days for slab; 2–4 days for erection depending on weather and crew size.

Can I add solar or a carport extension later?

Yes—discuss roof loading upfront. Many owners add custom carports Melbourne-style to the side bay, or upgrade to a 6m x 8m shed for extra depth.

Is Zincalume OK inland?

Yes, for non-marine environments Zincalume is a cost-effective choice for DIY shed kits and rural sheds NSW, provided gutters and drainage are managed.

Australian standards, climate, and resources

Data points reflect typical market ranges and 2024–2025 trade rates in capital cities and major regional centres; remote and cyclonic areas cost more.
