Garage for Sale Australia: Custom Colorbond Garages, Sheds and Carports

What makes a premium “garage for sale” in Australia?

A premium garage isn’t just a roller door and a slab. It’s a site-specific engineered building—usually a custom-built double garage in Perth or a cyclone-rated shed in North QLD—using high-tensile Colorbond or Zincalume, compliant with AS/NZS codes, and designed for local wind, corrosion and usage needs.

• Engineered wind rating (N2–N5 or C2–C3 for cyclonic regions)
• Genuine BlueScope Colorbond or Zincalume sheeting and purlins
• Site-specific engineering to AS/NZS 1170, AS 4100/4600, AS/NZS 1562
• Quality fit-out: B&D roller doors, windlocks, personal access doors, vermin-proofing
• Thermal and condensation control: sarking or anticon blanket, roof ventilation

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

Perth’s hot summers and coastal air mean UV stability and corrosion resistance are critical—especially within 1 km of the coast. Colorbond’s paint system resists chalking and fading; Zincalume offers excellent base-metal corrosion resistance and is cost-effective.

Which garage size and roof style suits your site?

Match your vehicle height, access and rainfall to roof pitch and bay spans. A custom Colorbond garage in Sydney often chooses a gable for heritage streets, while a skillion roof in Perth pairs well with modern homes and solar panels.

Do I need council approval for a garage in WA, NSW, QLD or VIC?

Most custom garages require building approval and often planning consent. Many councils accept certified, site-specific engineering with wind classification, slab spec and drainage details.

How to Get Council Approval for Your Custom Shed in WA

1. Confirm R-Codes and local TPS setbacks, height limits and site coverage.
2. Obtain site classification (wind region A–D; terrain category; topography). Added 2024 WA wind-rating compliance notes
3. Submit BA2/BA3 with engineering to AS/NZS 1170, AS 4100/4600 and slab design to AS 2870.
4. Provide site plan, elevations, stormwater drainage and neighbour consultation if required.
5. For coastal builds, include corrosion protection notes and material specs.

NSW fast facts

• Complying Development can apply if size, height and setbacks fit SEPP rules.
• Rural zones may allow larger rural sheds NSW with simpler pathways.

QLD and cyclonic areas

• North QLD requires C2–C3 wind ratings and cyclonic detailing. Gap: cyclone-rated sheds QLD
• Use region-specific fixings, windlocks and door bracing. Townsville/Cairns sites often need enhanced roller door wind ratings.

VIC quick notes

• Check bushfire Attack Level (BAL) for cladding and ember protection in regional zones.

How much does a custom-built garage cost in 2025?

Indicative pricing only; allow for site access, slab thickness, wind rating and options.

• Single garage kit (non-cyclonic): $4,900–$8,500
• Double garage kit: $7,900–$12,500
• Triple-bay garage kit: $12,000–$19,500
• Fully installed double garage (incl. slab): $18,000–$35,000+
• Cyclonic upgrade (C2–C3): +10–25%
• Insulation (anticon, roof panels), windows, automated B&D doors: +$1,500–$6,000

Real 2024–2025 steel cost movements have stabilised compared with 2022 spikes, but freight and labour vary by region (see Australian Steel Institute outlook and HIA reports linked below).

Are sheds wind-rated and engineered for my area?

Yes—reputable suppliers design to your site wind classification, exposure and terrain category. For example, a custom Colorbond garage in Perth’s inland suburbs might be N3 with standard fixings, while a coastal Geraldton garage could need N4 components and additional corrosion detailing. Gap: council-approved sheds WA

• Standards: AS/NZS 1170 (loads), AS 4100/4600 (steel), AS/NZS 1562 (sheeting), AS/NZS 3500 (stormwater), AS 2870 (slab)
• Door windlocks and extra jamb bracing for high-wind doors
• Anchors, hold-downs and purlin spacing adjusted for N/C ratings

DIY shed kits vs custom-built: which is better?

5-Step Buying Guide for Custom Sheds in Australia

1. Define use: vehicles, workshop, farm machinery storage, or mixed-use.
2. Pick size and roof: double garage, triple bay, gable vs skillion; set minimum 2.4 m clearance for SUVs/utes.
3. Choose materials: Colorbond vs Zincalume; add sarking/anticon for heat and condensation control.
4. Engineer for site: confirm N/C wind rating, terrain category, coastal corrosion strategy.
5. Plan approvals and build: council, slab design, stormwater, power/water, security (PA door, windows, automation).

Frequently asked questions

How long is delivery and install?

Kit lead times are typically 2–6 weeks; installs 2–5 days depending on size and weather.

What slab thickness do I need?

Commonly 100–120 mm with N12/N16 bars and mesh; engineer must certify to AS 2870 and use loads (point loads under portal frames).

Can I add solar or battery storage?

Yes, especially on skillion roofs with north-facing pitches. Confirm rafter/purlin capacity for panel loads.

What about termites and condensation?

Steel frames are termite-proof. Manage condensation with sarking/anticon, vents and sealed penetrations.

Coastal sites?

Use Colorbond Ultra where applicable, stainless fixings near splash zones, and rinse schedules for high sea spray areas.

Snow or alpine loads (TAS/VIC High Country)?

Request snow load design to AS/NZS 1170 with increased roof capacity.
