Build vs rent: What does a Colorbond steel shed in Perth actually cost?

For many homeowners and renovators, a custom Colorbond garage or backyard shed is better value than ongoing storage unit costs Perth. Here’s a realistic 2025 price guide for metro Perth (flat site, good access):

Typical installed price ranges (incl. slab and engineering)

  • Small garden/storage shed (3×3 m, 2.1–2.4 m high): $4,500–$8,000
  • Mid-size shed (3×6 m): $7,500–$13,500
  • Custom-built single garage (3.5×6 m): $11,000–$19,000
  • Custom-built double garage in Perth (6×6 m): $18,000–$32,000
  • Boat/caravan shed (varies: 3.6–4.2 m eave height): $14,000–$35,000

Inclusions typically cover: engineering to AS/NZS 1170.2 (wind), AS/NZS 4600 (cold-formed steel), site-specific plans for council, slab-on-ground (100–120 mm N20 concrete), hold-downs, and Colorbond cladding. Upgrades: insulation, roller doors, vermin flashing, skylights, power, and stormwater.

Rule of thumb: If you’re renting a 3×3 m unit at $280/month, you’ll pay ~$3,360 per year. Over two years, that’s ~$6,720 with fee increases. A 3×3 m installed Colorbond shed can be similar money once — and it adds value to your property.

Case studies: When a shed beats the cheapest storage units in Perth

Case Study 1 — Willetton Renovation (9 m² space needed, 12 months)

  • Self storage (3×3 m): $260/month x 12 = $3,120 + fees (~$150) = ~$3,270
  • Colorbond shed (3×3 m, slab, council-ready): ~$5,800 installed

Break-even versus renting is just under 24 months. Owner kept the shed for garden tools and bikes post-reno — no more storage bills.

Case Study 2 — Wanneroo Investor (18 m² space needed, 24 months)

  • Self storage (3×6 m): $380/month x 24 = $9,120 + fees/insurance (~$500) = ~$9,620
  • Colorbond double door shed (3×6 m, insulated roof): ~$12,500 installed

Shed cost more upfront, but investor retained asset for tenancy storage, improving rentability and valuation.

What are the best shed materials for Perth’s climate?

Perth summers are hot and dry; coastal suburbs add salt exposure. Choose materials that handle heat, UV, and corrosion.

Colorbond vs Zincalume — Which is better for WA conditions?

Attribute Colorbond Steel Zincalume Steel
Finish Painted, baked-on colour layer Metallic (Al-Zn-Mg)
Heat/UV resistance Excellent; solar reflective colours reduce heat gain Good, but can be hotter under direct sun
Coastal performance Colorbond Ultra recommended within ~200–400 m of surf Fair; surface spotting can occur nearer to coasts
Aesthetics Large Colorbond palette (Monument, Surfmist, etc.) Industrial silver/grey only
Price Higher upfront Lower upfront
Resale appeal Strong (adds street appeal and value) Functional; less premium look

Verdict: For most Perth homes, Colorbond offers better heat performance, colour choice, and coastal durability, particularly in sea-breeze suburbs.

Roof style and build approach: what’s best value?

Flat (skillion) vs gable roof

Option Pros Cons Best for
Skillion Cheaper, simple drainage, modern look Lower internal height at back, wind uplift needs detailing Side setbacks, minimalist designs
Gable Classic look, better headroom and airflow Slightly higher cost, more components Garages, workshop sheds, aesthetics

DIY shed kit vs custom-built, council-ready

Approach Pros Cons Budget ballpark
DIY kit Lowest cost materials, fast supply Owner manages slab, council, compliance, and build From ~$1,200–$6,000 (kit only)
Custom, council-approved build One point of contact, engineered, compliant, warranties Higher upfront price From ~$4,500–$32,000 installed (size dependent)

How to choose the right shed: 5-step buying guide for Australian homeowners

  1. Define use and clearance: shelving, vehicle, boat, or farm machinery storage. Measure vehicles with doors open and tow hitches on.
  2. Pick wind rating and location: Perth metro is generally Region A (N2/N3). Exposed or coastal sites may require higher ratings. See notes below.
  3. Select materials: Colorbond vs Zincalume; add roof insulation and ventilation for heat control.
  4. Decide on access: roller door width/height, PA doors, driveway fall, stormwater discharge.
  5. Plan approvals and services: site plan, setbacks, NCC compliance, slab and power.

How to get council approval for your custom shed in WA

Actionable steps for council-approved sheds WA

  1. Check local planning rules: lot size, setbacks, open space. Each council publishes outbuilding guidelines.
  2. Confirm if exempt: Very small sheds may be exempt from a building permit, but most garages/outbuildings need approval.
  3. Prepare documents: site plan, elevations, slab detail, engineering to AS/NZS 1170.2 and NCC 2022, specifications.

Perth wind ratings and engineering: what changed recently?

Added 2024 WA wind-rating compliance notes

  • Most Perth metro sites: Region A, N2 or N3 classification per AS/NZS 1170.2.
  • Coastal/exposed sites (e.g., dunes, open terrain): may require higher pressures, extra hold-downs, and more screws per sheet.
  • Northern WA (Pilbara/Kimberley): Region D (cyclonic). If you own a holiday or investment property up north, specify wind-rated sheds for cyclonic areas and consider cyclone-rated sheds QLD standards as a benchmark.

Engineering should also reference AS/NZS 4600 (cold-formed steel), AS 4100 (steel structures), and NCC 2022. See the Australian Steel Institute for guidance.
