Warehouse Cost in Australia (2025): Sheds, Garages and Industrial Steel Buildings
Primary keyword: warehouse cost | Secondary keyword: how much does a warehouse cost
This guide takes a practical, Australian-first view for homeowners, renovators, and property investors comparing Colorbond steel sheds, custom garages, rural sheds, and industrial warehouses.
How much does a warehouse cost in Australia in 2025?
Short answer: it depends on size, wind region, cladding (Colorbond vs Zincalume), slab thickness, eave height, and fit-out. Here are ballpark build-only price ranges (ex-GST) to help you plan:
- DIY shed kits (single garage to small workshop): approx. $150–$300 per m²
- Custom Colorbond garages and premium workshops: approx. $350–$900 per m²
- Rural/farm sheds (open bays or partial walls): approx. $250–$650 per m²
- Cold-shell industrial warehouse (no office fit-out): approx. $900–$1,800 per m²
- Warehouse with office/amenities fit-out: approx. $1,500–$3,000+ per m²
Allow extra for site works, engineering, permits, cyclonic upgrades, services, and contingencies.
What drives warehouse and shed costs?
- Wind region and terrain: AS/NZS 1170.2 wind Region A–D; cyclonic Region C/D (parts of QLD/WA) increases steel size, connections, and hold-downs. Added 2024 WA wind-rating compliance notes
- Dimensions: Wider spans, higher eaves, and long bay spacing increase steel tonnage and crane time.
- Cladding: Colorbond vs Zincalume, sheet thickness, and anti-condensation blankets or insulated roof panels.
- Open vs enclosed bays: Rural sheds with open fronts cost less than fully enclosed workshops with roller doors and windows.
- Concrete slab: Thickness (100–200 mm+), reinforcement, footings, and forklift load specs.
- Doors and access: Large industrial roller doors, PA doors, glazing, louvres, vermin-proofing.
- Fit-out: Office mezzanines, amenities, fire protection, ESFR sprinklers (where required), electrical, solar.
- Location and logistics: Remote or regional delivery, crane access, sandy vs clay sites, and stormwater requirements.
Typical line items and realistic allowances
- Engineering and certified drawings: $1,200–$8,000+ (size and wind region dependent)
- Concrete slab and footings: $120–$180 per m² for standard residential slabs; $180–$350+ per m² for heavier industrial loads
- Erection (labour, plant, crane): 20–35% of kit value for non-cyclonic; 30–45% for cyclonic regions
- Insulation/blankets or insulated panels: $12–$80 per m² roof area
- Roller doors (residential): from $1,100–$3,500; commercial extra-wide/high from $4,000–$12,000+
- Gutters, downpipes, and stormwater: $1,500–$8,000+ (size and council drainage rules)
- Council/permit fees: $500–$4,000+ (planning + building permits, region dependent)
Colorbond vs Zincalume — which is better for WA conditions?
| Feature | Colorbond | Zincalume |
|---|---|---|
| Finish | Pre-painted with durable coatings; wide colour selection | Metallic silver finish; paint later if desired |
| Corrosion resistance | Excellent; choose Colorbond Ultra near marine environments | Good; may weather faster near coast |
| Cost | Higher upfront | Lower upfront |
| Heat performance | Thermatech options can lower heat gain; pairs well with insulation | Reflective but less thermal optimisation options |
| Best use | Premium homes, custom Colorbond garages Perth, coastal sheds | Budget farm sheds, non-coastal rural storage |
What are the best shed materials for Perth’s climate?
- Colorbond Ultra or standard Colorbond with marine-grade fixings if you’re within 1 km of surf
- Zincalume for inland or rural WA where budget is key
- Insulated roof panels or at least R1.3–R2.5 roof blankets to manage heat and condensation
- Hot-dip galvanised purlins and columns for exposed coastal sites or fertiliser storage environments
How to get council approval for your custom shed in WA
Step-by-step (typical pathway)
- Check local planning rules (LPS/R-Codes) for setbacks, height, and site coverage.
- Obtain engineering-certified drawings and site plan (showing stormwater, slab, and setbacks).
- Choose certified (BA1) or uncertified (BA2) Building Permit application under the WA Building Act 2011.
- Lodge with required documents: energy provisions (NCC 2022), structural certification, bushfire (BAL, if applicable), and owner/builder or builder details.
- On approval, schedule slab, delivery, and erection; book mandatory inspections if specified by your permit.
Other states: NSW may require DA or CDC; QLD private certifiers can assess Class 10a sheds; always confirm local requirements.

|---|---|---|
| Upfront cost | Lower | Higher |
| Time/skill required | High — owner coordinates slab and erection | Lower — single point of accountability |
| Design flexibility | Standard spans/heights | Custom eave height, bay spacing, openings |
| Council paperwork | Owner-managed | Builder often handles |
| Best for | Budget workshops, DIY shed kits | Premium custom Colorbond garages Perth, complex sites, warehouses |
FAQ — Your warehouse cost and shed questions answered
What wind rating do I need?
It’s site-specific. Use AS/NZS 1170.2 and local terrain/exposure assessments. Coastal QLD and WA north are often Region C/D (cyclonic), needing higher-spec frames and fixings.
Do I need a slab?
For garages and warehouses, yes — slab thickness and reinforcement depend on loads (cars vs forklifts). Some rural hay sheds can start with piers and compacted gravel, adding slabs later.
What about bushfire (BAL) and corrosion zones?
BAL ratings in bushfire-prone areas affect cladding, ember protection, and glazing. Coastal corrosion zones call for Colorbond Ultra or galvanised components and stainless fixings.
How long does it take?
Lead times fluctuate with steel supply. Typical: 1–3 weeks for approvals, 2–6 weeks for fabrication, and 1–3 weeks for erection (size/region dependent).
Is Colorbond worth it over Zincalume?
For premium homes, coastal locations, and heat management, Colorbond usually pays back in durability and aesthetics. Inland budget rural sheds may suit Zincalume.
Local compliance, standards and climate notes
- NCC 2022 (BCA): Energy and structural provisions apply to Class 10a sheds and Class 7b warehouses.
- AS/NZS 1170.2: Wind actions — ensure engineering matches your region.
- Stormwater and permeability: Councils may require on-site retention or specific gutter/downpipe sizing.
- Heat and cyclones: Use higher-spec cladding and connections for cyclonic areas; insulated roofs reduce peak internal temperatures in Perth and inland NSW/SA.
