Mower Shed Buyer’s Guide for Australian Homes: COLORBOND Lawn Mower Storage, Wind Ratings, Approvals

1 Nov Machinery Shed Design

What size mower shed do I need?

Match the footprint to your mower type and access needs. Always allow for safe turning and tool storage (fuel, trimmer, blower).

  • Push mower + tools: 1.5m × 1.5m to 2.3m × 1.5m (little shed / lawn locker shed)
  • Large push mower + shelving: 2.3m × 1.5m to 3m × 1.5m
  • Ride-on mower storage: 3m × 3m up to 4.5m × 3m with double doors and ramp
  • Shared garden storage (bikes + mower): 3m × 2.3m to 4.5m × 2.3m

Tip: Double-door width of 1.5–2.4m makes manoeuvring easier, especially on sloped blocks.

Definition — Lawn locker shed: A compact, low-height storage unit with wide doors designed for mowers and garden tools, often under exempt development size limits.

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

Hot summers, coastal corrosion, and strong seabreezes mean your outdoor lawn mower storage should use Australian steel and compliant fixings. Below is a practical comparison.

COLORBOND vs ZINCALUME — Which is better for WA conditions?

Feature COLORBOND steel ZINCALUME steel
Coating Painted, oven-cured finish over alloy-coated steel Aluminium-Zinc alloy coating (no paint)
Heat reflectivity High in lighter colours (e.g., Surfmist) Good, metallic finish reflects heat
Corrosion resistance (coastal) Excellent in non-splash zones; maintain wash-down near surf Very good; may show patina in harsh salt zones
Aesthetic longevity Outstanding colour retention with warranty Industrial look; can be painted later
Cost Higher upfront Lower upfront
Best for Premium, coastal, or street-facing installs Budget-friendly, rural or utility installs
Definition — COLORBOND vs ZINCALUME: Both are Australian steel products to AS 1397. COLORBOND has a painted finish; ZINCALUME is an aluminium-zinc alloy coating without paint.

Add 10–25% for cyclone-rated sheds QLD and coastal corrosion upgrades (stainless fixings, marine wash-down clearance).


How to choose doors, floors, and ventilation for a lawn mower shed

Doors and access

  • Double hinged or sliding doors: 1.5–2.4m clear opening for ride-on mowers
  • Low-profile threshold or aluminium ramp for easy rolling
  • Security: key-lockable latch, concealed hinges, pad bolt plates

Flooring and slab

  • Concrete slab: 100mm thick with SL62 mesh, to AS 2870
  • Timber deck on piers for reactive clay sites; use termite-resistant framing
  • Anchors: M10-M12 expansion or chemical anchors to engineer spec

Ventilation and condensation control

  • High–low louvres or ridge vent to purge petrol fumes
  • Anti-condensation blanket under roof sheets
  • Insulated roof panels for heat control (see Pro Tip)
Definition — Anti-condensation blanket: A fleece-backed membrane bonded to roof sheets that absorbs moisture and reduces condensation drip.
Pro Tip: Using insulated roof panels can reduce internal shed temperatures by up to 10°C in summer, ideal for Perth, Adelaide and inland NSW heat.

Do I need council approval for a mower shed?

Rules vary by state and council. Small “exempt” garden sheds are often permitted below certain height and area limits, but always check.

How to Get Council Approval for Your Custom Shed in WA

  1. Confirm exemption: Many WA councils exempt small sheds under set size/height; check local planning scheme.
  2. Site plan: Show setbacks, easements, stormwater path to soakwell.
  3. Engineering: Wind rating to AS/NZS 1170.2 and footing/slab details to AS 2870.
  4. Materials schedule: COLORBOND/ZINCALUME to AS 1397, corrosion category per AS 4312.
  5. Lodge building permit (BA2 or BA13, as applicable) with fees.

If time-poor, ask for council-approved sheds WA packaged with plans and engineering certificates.


Wind ratings and compliance by region

Australia’s wind regions define design loads. Ensure your mower shed supplier certifies the correct wind classification and fixings.

  • Non-cyclonic: N1–N3 (e.g., VIC suburbs, inland NSW) — common for small sheds
  • Cyclonic: C1–C3/C4 (coastal QLD, NT north) — requires stronger frames and fixings
  • Site specifics: Terrain category, shielding, topography, and importance level per AS/NZS 1170.2

Added 2024 WA wind-rating compliance notes: Coastal WA suburbs (e.g., Perth’s coastal strip) often require N2–N3; Geraldton and far north can approach cyclonic classifications. Ask for wind-rated sheds for cyclonic areas if on the edge of C regions.

Definition — Wind classification: A letter/number (e.g., N2, C2) indicating design wind speeds and pressures used to engineer a compliant structure to AS/NZS 1170.2.

DIY shed kits vs custom-built: which suits you?

Option Pros Cons Best for
DIY shed kits Cheapest, quick delivery, weekend install, great for small yards Limited custom sizes, basic wind ratings, time and tools needed Little shed, lawn locker shed, budget outdoor lawn mower storage
Custom-built Engineered for site, council-ready plans, higher wind/corrosion performance Higher cost, lead time for approvals Ride-on mower storage, coastal or cyclonic sites, premium finishes

Flat roof vs gable roof for mower sheds

Roof style Advantages Considerations
Flat (skillion) Low profile, easy to place under fences/eaves, simple water fall to rear Less headroom; ensure adequate fall and guttering
Gable Better ventilation volume, classic look, easier ridge venting Taller overall height; may affect council height limits

Real-world build examples (Australia)

Perth, WA — Heat-resistant mower shed

3m × 2.3m COLORBOND Surfmist, skillion roof, anti-condensation blanket, whirlybird, 100mm slab on sand pad with SL62 mesh. Result: cooler internal temps and no condensation drip in morning sea breeze. Demand from steel sheds Perth homeowners for lighter colours improving thermal comfort.

Townsville, QLD — Cyclone-rated ride-on mower storage

5-Step Buying Guide for Custom Sheds in Australia

  1. Measure and map: mower dimensions, turning radius, door width, and yard access path.
  2. Choose materials: COLORBOND for street-facing, ZINCALUME for budget; select coastal upgrade if within 1 km of surf.
  3. Engineer for wind: confirm N or C classification to AS/NZS 1170.2 with certified drawings.
  4. Plan the base: slab thickness (100mm), drainage, and termite barriers; set door threshold to avoid trip lips.
  5. Approval and install: submit drawings, schedule delivery, and book a licensed installer or a capable tradie mate.

Australian standards and specs that matter

  • AS/NZS 1170.2 — Wind actions
  • AS 2870 — Residential slabs and footings

  • AS/NZS 3500.3 — Stormwater drainage (for gutters and downpipes to soakwell)
  • AS 3959 — Bushfire attack level (BAL) — consider in bushfire-prone areas
Definition — BAL rating: A Bushfire Attack Level classification affecting material and construction requirements in bushfire-prone areas.

Frequently asked questions

Do small mower sheds need permits?

Often exempt if under set size/height, but thresholds differ by council. When in doubt, ask for a council-approved shed package with drawings.

What slab do I need?

Typical: 100mm concrete with SL62 mesh, M10–M12 anchors. For sloping sites, consider thickened edges or piers as per engineer.

How do I manage fuel fumes?

Include cross-ventilation (louvres) and store fuel in a certified jerry can on a low shelf. Keep ignition sources away.

Will COLORBOND fade?

Modern COLORBOND has excellent colour retention with manufacturer warranties. Choose lighter colours for heat reduction.

Coastal rust risk?

Specify coastal upgrades: stainless or class 4 fasteners, increased wash-down clearance, gutters to controlled drainage.

Lead times in 2025?

DIY kits: 1–3 weeks. Custom, council-approved: 4–10 weeks depending on engineering and permit queues.
