Garaport Sheds Australia: Custom Colorbond Garages + Carports (2025 Guide)

23 Oct Garage Sheds

If you’re weighing up a garaport shed for your property, you likely want three things: a secure lock-up for vehicles and tools, a covered area for everyday parking or projects, and a structure that will sail through council and last decades in Australian conditions. This guide breaks down everything from Colorbond vs Zincalume to wind ratings, council approvals, and whether a garaport kit or fully custom build is the smarter choice.

What is a Garaport Shed — and Why Do Aussies Choose It?

Definition — Garaport shed: A hybrid building combining an enclosed garage (lock-up) with an attached carport (open bay) under a continuous roof line. Often specified as a double garage with a skillion or gable roof and one or more open bays for everyday parking, boats, or farm machinery.
  • Popular configurations: double garage with 1–2 open bays; triple-bay garaport with central lock-up; drive-through garaport for boat trailers or caravans.
  • Best for: family homes needing shaded parking, rural properties needing farm machinery storage, investors adding value with an affordable carport + custom Colorbond garage.
  • Common upgrades: insulated roof panels, mezzanine storage, roller doors with automation, heavy-duty gutters/downpipes, vermin flashing, whirlybirds and skylights.

Typical search terms you may have used include: steel sheds Perth, custom carports Melbourne, rural sheds NSW, cyclone-rated sheds QLD, custom Colorbond garages Perth, DIY shed kits, and wind-rated sheds for cyclonic areas.

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

Hot summers, high UV and coastal air around WA hammer cheaper cladding. For garaport sheds, your main decision is Colorbond vs Zincalume.

Colorbond vs Zincalume — Which Is Better for WA Conditions?

Criteria Colorbond Steel (including Ultra/Matt) Zincalume Steel
UV resistance (Perth heat) Excellent paint system resists chalking/fading; wide Colorbond colour range Good base coating, but reflective silver finish can show weathering
Coastal corrosion resistance Colorbond Ultra recommended for severe marine (check distance to surf) Good inland; consider upgrades near the coast
Aesthetics and value add Premium look; better curb appeal for homes and strata Utilitarian look; suits rural or budget builds
Cost Higher upfront, often lower lifecycle cost Lower upfront cost
Availability of profiles All common shed cladding/roof profiles available All common shed cladding/roof profiles available
Definition — Corrosion categories (AS 4312): Site exposure ratings (e.g., C2–C5, CX) based on distance to coast/industry. Higher categories need higher-spec coatings (e.g., Colorbond Ultra) and vigilant detailing.

Pro Tip: Using insulated roof panels or a sarking + blanket combo can reduce internal shed temperatures by up to 10°C in summer, improve acoustic comfort, and reduce condensation risk.

How Do Wind Ratings and Building Codes Affect Garaport Sheds?

Australian garaports must be engineered to AS/NZS 1170.2 (wind actions) and the National Construction Code (NCC 2022). Your design will be certified for a wind region (A, B, C, D), terrain category, and importance level. Coastal QLD and NT often require cyclone detailing; parts of WA also demand high tie-down capacity.

Definition — Wind region/N rating: Region A–D (per AS/NZS 1170.2) and Non-Cyclonic N1–N4/Cyclonic C1–C4 classification that determines frame spacing, hold-downs, sheeting screws, and door wind-locks.
  • QLD/NT: Specify cyclone-rated sheds (Region C/D). Use wind-lock roller doors, heavier purlins, and upgraded footings.
  • WA: Northern coastal and Pilbara sites often need C ratings; Perth metro is mostly Region A/B but confirm site wind speed and terrain category.
  • NSW/ACT/VIC/SA/TAS: Mostly N2–N3; alpine TAS/NSW require snow and uplift checks.

Added 2024 WA wind-rating compliance notes Ensure your engineering cert nominates the correct region and terrain, and that anchor schedules match your slab and soil report. Include site-specific engineering certification and a tie-down plan for all open-bay posts.

How to Get Council Approval for Your Custom Shed in WA

Step-by-step: Council-Approved Sheds WA

  1. Planning check: Confirm setbacks, height, and open space with your local scheme.
  2. Certified or Uncertified path: In WA, a private building surveyor can issue a BA3 Certificate of Design Compliance (CDC) for a BA1 application, or you can lodge BA2 directly.
  3. Documents: Site plan, elevations, engineering (AS/NZS 1170.2, AS/NZS 4600), slab details, drainage, bushfire BAL if applicable.
  4. Lodge building permit: Typical processing 10–25 business days if complete.
  5. Inspections: Footings/slab and final. Retain certificates and warranties for handover.

We design and supply council-approved sheds WA with certified drawings, reducing delays for Perth, Peel and South West clients.

What About Other States?

  • QLD: Building approval + Form 15/16 engineering certifications. For coastal/whirly zones, specify cyclone-rated sheds QLD with compliant door wind-locks.
  • NSW/ACT: DA or Complying Development depending on size and setbacks. BAL assessment in bushfire-prone areas.
  • VIC/SA/TAS: Building permit through a registered building surveyor; check overlays (heritage, flooding, coastal).

Should You Buy a Garaport Kit or Go Custom-Built?

DIY Shed Kits vs Custom-Built — What’s Better for You?

Aspect DIY Garaport Kit Custom-Built (Supply + Install)
Cost Lower upfront; you arrange slab, erection, and approvals Higher upfront; bundled approvals, engineering and install
Time Suited to owner-builders with weekends available Faster overall delivery with a single point of accountability
Complexity Best for simple, non-cyclonic sites Ideal for sloping blocks, cyclonic regions, BAL or coastal
Warranty/Compliance Component warranties; install quality depends on you Workmanship + product warranties; QA and certifications handled
Upgrades Available but may require extra planning Seamless integration of insulation, mezzanine, automation

Many owners start with a garaport kit for budget control, then add features. If you’re in Perth metro and want a turnkey custom Colorbond garages Perth solution, a managed install avoids rework and compliance issues.

Which Roof Profile Suits Your Site? Skillion vs Gable vs Flat

  • Gable roof: Classic look, strong in high wind uplift, good for integrated carport spans.
  • Skillion roof: Modern profile with single fall; great for custom carports Melbourne and tight setbacks.
  • Flat roof: Clean lines for low visual impact; ensure adequate fall for drainage and leaf-guarded gutters.

Consider driveway gradients for headroom under the carport and specify gutter capacity for local rainfall intensities (see Bureau of Meteorology IFD data).

Design Options That Add Real-World Value

  • Roller doors with wind-locks and automation
  • PA doors and security windows with flyscreens
  • Insulation (roof/walls), sarking and condensation control
  • Mezzanine storage for boxes or kayaks
  • Concrete slab with thickened edges or piers-on-pads for rural soils
  • Gutters, downpipes to soakwells or legal stormwater point
  • Vermin flashing, bollards at carport posts, and LED lighting
