Quaker Barn: The Complete Australian Guide to Design, Compliance and Pricing (2025)

26 Oct American Barns

For Australian homeowners, renovators, and property investors, a Quaker barn combines timeless barn styling with modern steel engineering. Below you’ll find everything you need to spec, price, and approve a premium-quality Colorbond steel shed or Quaker barn house—optimised for Australian conditions from Perth heat to QLD cyclones.

What is a Quaker Barn?

A Quaker barn is a two-level, barn-style steel building with a raised centre bay and side lean-tos. The taller mid-bay allows for a mezzanine or loft, while the side bays suit vehicles, a workshop, or storage. Compared with an American barn, a Quaker profile often features a steeper central pitch and a symmetrical, heritage look that suits Australian rural blocks and lifestyle lots.

Quaker barns are unique in both style and function, providing ample storage with a distinctive roof profile. For those seeking more than just storage, they can also be adapted as a barndominium option, blending lifestyle with utility.

The symmetrical design and striking roofline provide both function and curb appeal. For those inspired to incorporate these features into a residence, our collection of Australian modern barn house plans offers practical and stylish solutions.

Definition — Quaker Barn: A portal-frame steel barn with a higher centre section and two lower side aisles (lean-tos), commonly with mezzanine storage and wide door openings.

Why Choose a Quaker Barn in Australia?

  • Space efficiency: Mezzanine-ready centre bay doubles usable floor area for tools, hay, or a home office.
  • Versatility: Configure as a farm workshop, custom-built double garage, boat storage, or a Quaker barn house (habitable) with council certification.
  • Street appeal: Heritage profile pairs well with Colorbond colours for acreage and coastal properties.
  • Strength: Hot-dipped galvanised portal frames, RHS columns, and cyclonic tie-down options for Regions C/D.
  • Value: DIY shed kits or turnkey builds to suit budget and timeline.

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

Perth’s hot summers and coastal salt exposure demand roofing and walling that can handle heat and corrosion. Most premium quaker barns use BlueScope steel cladding—either Colorbond or Zincalume—with structural steel frames and galvanised purlins/girts.

Definition — Colorbond Steel: Pre-painted, oven-baked finish on Zincalume substrate (by BlueScope), offering colour durability, corrosion resistance, and modern colours (incl. Colorbond Ultra for severe marine).
Definition — Zincalume: Zinc/Aluminium alloy coated steel (AZ150 typical) with a silvery finish; excellent base corrosion resistance for rural sheds and carports.

Colorbond vs Zincalume — Which Is Better for WA Conditions?

Feature Colorbond Zincalume
Heat reflectivity High (Thermatech in many colours) High (light reflectivity of bare metal)
Coastal corrosion resistance Excellent with Colorbond Ultra near surf coasts Good; may need extra caution within 200–400 m of breaking surf
Aesthetics Wide modern colour range to match homes Industrial look; can weather unevenly
Maintenance Low; washdown in marine zones recommended Low; washdown in marine zones recommended
Cost Usually higher upfront Usually lower upfront
Best use in WA Coastal metro, harsh sun, premium looks Rural inland, farm machinery storage

For most Perth metro sites, Colorbond (often with sarking and roof insulation) is the pick. For inland WA and rural sheds, Zincalume cladding remains a durable, cost-effective option.

Engineering, Wind Ratings and Compliance

Australian quaker barns must be engineered to AS/NZS 1170.2 (wind actions), AS/NZS 4600 (cold-formed steel), and AS/NZS 4100 (steel structures). Your shed supplier should model your exact site wind region, terrain category, shielding, and topography, and issue site-specific engineering and slab/footing details.

Added 2024 WA wind-rating compliance notes: WA uses Regions A, B, C and D. Coastal north and northwest (e.g., Karratha) are cyclonic Regions C/D; metro Perth is typically Region A. Non-cyclonic ratings (N2–N3) suit most southern sites; cyclonic ratings (C2–C3) are required up north with upgraded purlins, closer screw spacings, and heavy-duty hold-downs. Always request wind-rated sheds for cyclonic areas.

Definition — BAL (Bushfire Attack Level): Classification under AS 3959 for bushfire-prone areas. A quaker barn house or habitable conversion must meet the site’s BAL requirements for cladding, ember protection, and glazing.

How to Get Council Approval for Your Custom Shed in WA

  1. Planning check: Confirm zoning, setbacks, and allowable outbuilding sizes with your local council.
  2. Engineering pack: Obtain site-specific engineering, slab or pier footing drawings, and tie-down details.
  3. Documentation: Provide a site plan, elevations, specs (Colorbond vs Zincalume), and stormwater plan.
  4. Apply: Lodge a Building Permit (WA Building Act 2011) via a certified or uncertified route.
  5. Inspection/Final: Arrange footing/slab inspections if required; obtain a Certificate of Construction Compliance where applicable.

Ask for council-approved sheds WA from the outset—your supplier should package plans, engineering, and compliance statements to streamline approval.

QLD, NSW, VIC notes

  • QLD: Cyclone-rated sheds QLD may require C2/C3 designs and Region C/D certification, plus Form 15/16 from a RPEQ engineer.
  • NSW: Rural sheds NSW approvals vary; Complying Development may be possible in some LGAs for non-habitable farm buildings.
  • VIC: Check bushfire overlays and flood controls; BAL and floor levels may influence design for a barn house conversion.

Design Options and Customisation

The traditional Quaker barn is known for its distinctive gambrel roof, multiple storage levels, and customizable doors. Incorporating sliding barn doors for barns can further enhance the functionality and charm of a Quaker barn.

  • Spans and bays: Common modules 3–4 m; centre bay heights 4.2–6.0 m for mezzanine storage.
  • Roof pitches: 10–30° central pitch; adjust for rainwater runoff and loft height.
  • Cladding: Colorbond or Zincalume; choose Colorbond Ultra in severe marine zones.
  • Doors: Roller doors, sectional doors, PA doors; custom Colorbond garages Perth can be integrated into a side bay.
  • Ventilation: Ridge vents, whirlybirds, wall louvres for workshops in hot regions.
  • Insulation: Roof sarking + R2.5–R3.5 bulk batts or insulated panels for comfort and condensation control.
  • Gutters and drainage: Box or quad gutters with adequately sized downpipes; add leaf-guards near trees.
  • Flooring: 100–125 mm reinforced slab for vehicles; thicker pads under hoists.
  • Finishes: Skylights, glass sliders, verandahs, or attached custom carports Melbourne.

Quaker Barn House: Turning Your Barn Into a Home

Converting a quaker barn to a quaker barn house requires shifting from a Class 10a (non-habitable) to a Class 1a (habitable) under the NCC. That means:

  • Thermal performance to NCC 2022 energy efficiency provisions.
  • BAL compliance in bushfire-prone areas.
  • Plumbing, fire safety, ventilation, waterproofing, and egress to Class 1a standards.
  • Structural certification for additional loads (e.g., stairs, bathrooms, internal linings).

Ask your designer for a “shed home WA” pathway with certified plans and an energy report. Expect higher costs than a standard storage shed due to habitable requirements.

Popular Use-Cases Across Australia

  • Farm machinery storage with wide roller doors and 3.6 m+ clearance.
  • Custom-built double garage in Perth with attached lean-to for a boat.
  • Workshop and hobby space with mezzanine loft and dust extraction.
  • Car collector storage with insulated roof and dehumidification.
  • DIY shed kits for regional owner-builders wanting to save on install.
  • Affordable carports for Australian homes integrated as a side bay.

Pricing, Lead Times and Installation

Indicative 2025 supply-and-install pricing in AUD (actual quotes vary by wind rating, terrain, cladding and doors):

  • 6×9 m Quaker-style (non-cyclonic N2, Zincalume, basic doors): from $18,000–$28,000 (kit); $30,000–$42,000 installed.
  • 8×12 m with mezzanine, Colorbond, insulation, 2× roller doors: $45,000–$70,000 installed (N2–N3).
  • Cyclone-rated C2/C3 builds (QLD/WA north) with heavy frames and tie-downs: +20–40% over non-cyclonic.

Lead times: 4–10 weeks for engineering and fabrication; 3–7 days on-site for erection depending on slab and weather. 2024 Australian Steel Market Outlook suggests steady steel supply after early-2020s volatility; local lead times are improving in 2025.

DIY Shed Kits vs Custom-Built

  • DIY shed kits: Cheapest; you handle slab, council, and erection. Best for experienced owner-builders.
  • Custom-built/turnkey: Supplier manages council, slab, and install—faster and lower risk for complex sites or cyclonic ratings.

  2. Site and code: Confirm wind region, BAL, flood, and soil class. Request site-specific engineering.
  3. Choose materials: Colorbond vs Zincalume comparison; insulation for heat and condensation.
  4. Council and paperwork: Aim for council-approved sheds WA/QLD/NSW/VIC with a complete pack.
  5. Compare quotes: Ensure apples-to-apples on wind rating (N2 vs N3 vs C2/C3), door specs, and install.

Maintenance and Warranty

  • Wash down coastal sheds every 3–6 months to remove salt spray.
  • Clear gutters and check downpipes before summer storms.
  • Re-seal penetrations and inspect fasteners annually in cyclonic regions.
  • Follow BlueScope warranties; use Colorbond Ultra within severe marine zones.

FAQs

Are Quaker barns cyclone-rated?

Yes—when engineered for Region C/D with C2/C3 ratings. Ask specifically for wind-rated sheds for cyclonic areas and cyclone-rated sheds QLD/WA north.

Do I always need council approval?

Most councils require a permit for sheds over a small threshold (often 10 m²). Your supplier should handle plans and engineering for a smoother approval.

What sizes are common?

From 6×9 m up to 10×20 m, with centre bay heights of 4.2–6.0 m to accommodate mezzanines and tall roller doors.

Can I add a carport or verandah later?

Yes. Many owners add custom carports Melbourne style or lean-tos as staged builds. Ensure new works remain compliant and tied into the existing frame.

What’s better value: Colorbond or Zincalume?

Zincalume is usually cheaper upfront; Colorbond offers colour stability and better coastal performance (use Colorbond Ultra near surf coasts).
