The Real Cost of Storage Units in Australia (2025) vs Building a Colorbond Shed

If you’re searching for the cost of storage units, you’re likely weighing monthly self storage prices against building a long‑term solution at home. This guide compares storage unit rates across Australia with the real cost of a premium Colorbond steel shed or custom carport, including council approvals, wind ratings, and climate considerations for Perth, QLD cyclonic regions, and beyond.

How much does a storage unit cost per month in Australia (2025)?

Prices vary by city, unit size, and features. Here’s what Australians are paying in 2024–2025 for self storage units prices (typical ranges):

Unit size (approx.) Common name Typical monthly cost Use case
1–2 m² Storage locker / mini storage $50–$120 Documents, small boxes
3 m² Small unit $120–$220 Apartment overflow
6–9 m² Medium unit $220–$450 1–2 bedroom move
10–15 m² Large unit $350–$650 3 bedroom home contents
18–27 m² Extra‑large / single garage size $550–$1,000 Vehicle or full house

Capital cities trend higher (Sydney/Melbourne/Brisbane), with Perth and Adelaide often mid‑range. Regional towns can be 10–20% cheaper. Climate control usually adds 15–25% to storage room rates.

What drives self storage prices?

  • Location and demand (CBD and inner suburbs cost more)
  • Size/height, ground floor vs lift access
  • Climate control and 24/7 access
  • Promotions vs ongoing self storage rates
  • Insurance and security level (CCTV, patrols)

Common add‑on fees to watch

  • Admin fee or deposit: $15–$50
  • Padlock: $15–$30
  • Insurance: typically $1.50–$3.00 per $1,000 cover per month
  • Late payment or exit notice fees
Definition — Self storage: A rented unit in a commercial facility. You pay monthly storage costs for space you don’t own.

How much does it cost to build storage at home (Colorbond shed or carport)?

For many homeowners and investors, a well‑designed Colorbond steel shed or custom Colorbond garage can outperform ongoing storage space cost. Below are typical 2024–2025 supply and installed ranges using quality Australian steel for common sizes.

Structure Typical size Supply only (kit) Installed incl. slab and approvals
Garden/utility shed 3 m x 3 m $1,800–$3,500 $4,500–$7,500
Single garage 3.5 m x 6 m $4,500–$8,500 $10,000–$18,000
Double garage 6 m x 6 m $6,500–$12,000 $14,000–$28,000
Rural shed (open bay) 9 m x 7 m $12,000–$25,000 $28,000–$55,000
Carport (single/double) 3 m x 6 m / 6 m x 6 m $2,500–$6,500 $5,500–$12,500

Options that add cost but improve performance and value:

  • Insulated roof panels or anti‑condensation blanket
  • Extra height, wider bays, mezzanine storage
  • Roller doors (manual/motorised), windows, PA doors
  • Electrical, lighting, whirlybirds, solar pre‑wire
  • Upgrading to wind‑rated sheds for cyclonic areas
Pro tip: Using insulated roof panels in Perth can reduce internal shed temperatures by up to 10°C in summer, improving usability and protecting stored goods.
Definition — Colorbond steel: Painted, pre‑finished steel by BlueScope designed for Australian conditions. Highly durable, low maintenance, and available in modern colours.

Case study: custom-built double garage in Perth vs renting

A homeowner compares a custom Colorbond garage in Perth (6×6 m, insulated roof, motorised door) at $22,000 installed to a 18–20 m² self storage unit at $650/month.

  • Self storage: $650 x 60 months ≈ $39,000
  • Built shed: ~$22,000 (once), adds property value and convenience
  • Break‑even: ~34 months vs how much is a storage unit per month over the long term

Storage unit vs steel shed: total cost of ownership

Factor Self storage Colorbond shed at home
Upfront cost Low (bond/lock/admin) Medium–High (kit, slab, install)
Monthly outgoings Ongoing rent + insurance Minimal (insurance/maintenance)
Convenience Travel, limited hours unless 24/7 On‑site, anytime access
Control & value No capital value Adds property value; flexible use
Climate/security Varies by facility Specify insulation, locks, cameras

For homeowners asking “how much does storage cost long‑term?”, the tipping point is often 2.5–5 years. If you’ll need space beyond 24–36 months, owning a shed usually wins on total value.

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

Perth heat, coastal air, and afternoon sea breezes challenge cheap imports. Choose Australian steel and coatings designed for UV and corrosion resistance.

Colorbond vs Zincalume — Which is better for WA conditions?

Feature Colorbond Zincalume
Finish Pre‑painted colour top coat Galvalume (zinc/aluminium) metallic
UV resistance Excellent (Perth summers) Very good, but can reflect glare
Coastal performance Strong; check salt spray distance Strong; similar coastal cautions
Aesthetics Wide colour range, premium look Industrial look, lower cost
Price $$ $
Definition — Zincalume: A zinc/aluminium coated steel by BlueScope known for corrosion resistance and longevity. Often chosen for roofs and regional projects.

Wind ratings, NCC and Australian Standards you should know

Quality steel sheds Perth, rural sheds NSW, and cyclone‑rated sheds QLD must be engineered to Australian Standards and the NCC 2022.

  • AS/NZS 1170.2 Wind actions: Wind Regions A–D, terrain category, shielding, importance level
  • AS/NZS 4600: Cold‑formed steel design (typical shed frames)
  • AS 4100: Steel structures (where applicable)
  • NCC 2022: Structural and site requirements
  • AS 3959: Bushfire (BAL) where relevant

Added 2024 WA wind-rating compliance notes: Most of Perth is Region A, but coastal and ridge sites can increase design pressures. Always supply the exact address, terrain category, and required importance level to your shed engineer.

Definition — Wind Region: BOM‑based map classifying wind speeds: A (non‑cyclonic), B (higher), C/D (cyclonic). Drives member sizes, hold‑downs and cladding spec.

How to get council approval for your custom shed in WA

  1. Confirm zoning and R‑Codes setbacks with your local council planning team.
  2. Engage an engineer for site‑specific wind-rated drawings (AS/NZS 1170.2).
  3. Prepare a site plan, elevations, and stormwater plan.
  4. Lodge a Building Permit (BA1/BA2). Allow 10–25 business days.
  5. Book footing and slab inspections if required, then final Occupancy/BA7.

We often deliver council-approved sheds WA as a turnkey service to save time.

Regional factors: Perth heat, QLD cyclones, coastal corrosion

  • Perth: Prioritise insulation, lighter roof colours, and ventilation to handle 35–40°C spells.
  • QLD north: Choose cyclone-rated sheds QLD with upgraded hold‑downs, purlin spacing, and door wind locks.
  • Coastal areas: Consider marine‑grade fasteners and increased maintenance intervals.

DIY shed kits vs custom-built install

Aspect DIY shed kits Custom-built
Cost Lower upfront Higher but turnkey
Time Weekends over 2–4+ weeks Professional crew: 1–5 days
Approvals You manage Builder manages
Quality control Depends on your skills Certified installers, warranties

5‑Step Buying Guide for Custom Sheds in Australia

  1. Define use and size: storage, workshop, farm machinery storage, boat/caravan.
  2. Confirm site constraints: services, setbacks, driveway widths, slope.
  3. Pick spec: Colorbond vs Zincalume comparison, roof style (skillion, gable), insulation, door types.
  4. Engineering and compliance: wind region, BAL, slab design, council-approved sheds WA or your state.
  5. Compare quotes apples‑to‑apples: steel grade, sheet thickness, inclusions, self storage unit rates vs TCO.

When renting a storage unit makes sense

  • Short‑term (renovation or move) under 6–12 months
  • No space or no approvals possible at home
  • Climate‑critical archive storage with monitored facilities

Keyword clusters and use‑cases we design for
