Garden Shed With Awning: 2025 Australian Guide to Colorbond Sheds With Awnings

29 Oct Heavy Duty Sheds

What is a garden shed with awning, and why do Australians love them?

A garden shed with awning combines an enclosed Colorbond steel shed with a fixed roofed “lean‑to” that extends from the shed wall. It’s ideal for mower parking, firewood, potting benches, bikes, kayaks or a shaded work bay. Compared with a stand‑alone patio, an integrated awning is cost‑efficient, uses shared gutters and structure, and keeps gear dry and out of UV.

Definition — Lean‑to Awning: A single‑slope (skillion) roof extension off the shed using matching purlins and sheeting. Often called a “shed awning”, “lean‑to”, or “veranda extension”.
  • Typical awning depths: 1.5–3.6 m (space for bins/bikes up to a small ute canopy).
  • Common roof pitches: 5°–15° skillion; gable add‑ons also available.
  • Cladding: Colorbond steel or Zincalume, to match the main shed.

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

Perth’s hot summers, high UV and coastal air call for high‑grade coated steel and smart heat management. For most backyards, premium Colorbond is the safe bet; Zincalume is a strong budget option inland.

Colorbond vs Zincalume — Which is better for WA conditions?

Feature Colorbond (e.g., Monument, Surfmist) Zincalume
Coating system Painted, multi‑layer corrosion and UV protection Aluminium/zinc alloy anti‑corrosion coating
Heat performance Lighter colours reflect more heat; Thermatech options Reflective when new; can dull over time
Coastal resistance Better near coast when installed to spec and maintained Good inland; requires extra care near surf/spray
Aesthetics Matches home palette; premium look Industrial look; budget‑friendly
Best fit Perth metro, coastal WA, high UV backyards Regional WA, dry inland sites and farm yards
Definition — Anti‑condensation blanket: A thin foil‑faced insulation (with or without glasswool) placed under roof sheets to reduce condensation drip and heat gain.
Pro tip: Using insulated roof panels or a roof blanket can cut internal shed temperatures by up to 10°C in summer, and reduce condensation on winter mornings (see guidance from energy efficiency resources at Energy.gov.au and CSIRO).

How big should the awning be, and which way should it face?

  • Depth: 2.4 m is a sweet spot for bikes, potting, or a mower. Go 3.0–3.6 m for a trailer or workbench with walking space.
  • Height: Match shed eave height; 2.1–2.4 m clear head height is comfortable. Check gutter fall and downpipe locations.
  • Orientation: In southern states, face north to catch winter sun and shade in summer. In the tropics, prioritise cross‑ventilation and shade from western sun.
  • Drainage: Size gutters and downpipes to AS/NZS 3500.3 and local rainfall intensities (consult Bureau of Meteorology maps).

What wind rating and engineering does your shed and awning need?

Australian sheds must be designed to AS/NZS 1170.2 (Wind Actions) and relevant cold‑formed steel standards. Your site’s wind region and terrain category drive purlin sizes, screw patterns, hold‑downs and footing design.

  • Non‑cyclonic: N2–N3 common in metro areas (e.g., steel sheds Perth, Melbourne suburbs).
  • Cyclonic: C1–C3 in QLD and NT coastal zones (think cyclone-rated sheds QLD). Awnings in these zones need upgraded fixings and bracing.
  • Engineering: Ask for a site‑specific certificate from a registered structural engineer (cold‑formed to AS/NZS 4600). QLD may require Form 15/16.
Definition — Importance Level: Per AS/NZS 1170, most domestic sheds are IL1 or IL2. IL2 attracts higher design loads and is common for larger habitable‑adjacent structures or where risk to property increases.

How to get council approval for your custom shed in WA

Most WA councils require a Building Permit for a garden shed with awning, depending on size, height and setbacks. Always confirm local planning rules before you order.

Step‑by‑step (WA)

  1. Check planning triggers: Setbacks, lot coverage, heritage/estate covenants. Some small sheds may be exempt, but awnings can change height and coverage.
  2. Get engineering: Site wind region, Terrain Category, importance level, and footing design to suit soil reactivity.
  3. Prepare drawings: Site plan, elevations, roof drainage, downpipe discharge to lawful point.
  4. Submit Building Permit (BA1/BA2): Include structural certificate, spec, and energy/insulation notes if required.
  5. Inspection & compliance: Slab/pier inspection (if requested), final sign‑off on completion.

Added 2024 WA wind‑rating compliance notes: Many coastal councils now seek explicit reference to AS/NZS 1170.2:2021 in the engineering and require corrosion category consideration for fixings within marine influence zones.

What about other states?

  • QLD: Building approval via private certifier or council. Cyclonic zones require enhanced connections; ask for Form 15/16.
  • NSW: Some sheds comply via exempt development, but awning size/height can trigger DA. Check bushfire AS 3959 BAL setbacks.
  • VIC/SA/TAS/NT: Local permit rules vary; wind category and boundary proximity are the usual triggers.

DIY shed awning kits vs custom builds — which suits you?

Both shed awning kits and fully custom designs can be compliant and long‑lasting. Choose based on your site, wind rating and finish level.

DIY shed awning kits (pros/cons)

  • Pros: Fast lead times, budget‑friendly, pre‑engineered for common sizes, ideal for DIY shed kits lovers.
  • Cons: Limited sizes/colours; may not suit cyclonic or coastal C4 corrosion zones without upgrades.

Custom‑built awnings (pros/cons)

  • Pros: Tailored to council-approved sheds WA, odd boundaries, steep sites, or matching a custom Colorbond garage in Perth. Easier to hit BAL and coastal specs.
  • Cons: Higher design cost; longer lead time; engineered sign‑off required.

Real Australian build examples

Perth (N3, coastal influence) — 3.0 x 3.0 m shed + 2.4 m awning

  • Cladding: Colorbond Monument walls, Surfmist roof for heat reflectance.
  • Upgrades: Anti‑condensation blanket; marine‑grade screws; sealed cut edges.
  • Outcome: Shaded potting bay; compliant downpipe to soakwell per council policy.

Sunshine Coast QLD (C2) — 6.0 x 4.0 m shed + 2.4 m awning

  • Frame: G550 cold‑formed C‑purlins with additional bracing to cyclonic schedule.
  • Fixings: Cyclone washers, increased screw density to engineer’s plan.
  • Outcome: cyclone-rated sheds QLD spec met; awning provides covered kayak and board storage.

Rural NSW (N2, BAL‑12.5) — 7.5 x 3.0 m garden shed + 3.0 m lean‑to

  • Use: Firewood and farm machinery storage under the awning.
  • Spec: Colorbond Woodland Grey, ember‑resistant mesh to gutters to suit AS 3959.
  • Outcome: Practical rural sheds NSW solution with compliant setbacks.

What about roof style: flat (skillion) vs gable awning?

  • Skillion/flat: Clean lines, simple drainage, cost‑effective. Best for narrow side setbacks and modern homes.
  • Gable: More headroom and airflow; classic look. Slightly higher build cost and more flashing complexity.

5‑Step Buying Guide for Custom Sheds in Australia

  1. Confirm site conditions: Wind region (N2/N3/C2), soil class, bushfire BAL, coastal corrosion category.
  2. Choose materials: Colorbond vs Zincalume comparison; pick colours to manage heat (lighter roofs). Consider anti‑condensation or insulated panels.
  3. Design the awning: Depth, pitch, gutter and downpipe layout, post spacing (SHS/RHS), and concrete pad vs pavers.
  4. Sort approvals: Plans, engineering to AS/NZS 1170.2 and AS/NZS 4600, and local council paperwork. In QLD, arrange Form 15/16.
  5. Lock in install: Decide DIY vs licensed installer. Schedule slab pour, delivery, and erection. Photograph hold‑downs for compliance.

Frequently asked questions

Do I need a concrete slab under the awning?

No, but it’s recommended. A slab keeps things level, reduces splashback corrosion, and makes anchoring posts easy. Where landscaping is preferred, use concrete footings for posts and stabilised compacted base.

Can I add solar to the awning roof?

Yes, if the frame and fixings are engineered for the additional dead load and uplift. Use approved brackets that don’t compromise roof sheeting warranties.

What does a garden shed with awning cost?

As a guide only: DIY shed awning kits from a few hundred dollars for small bays; fully engineered awnings on custom Colorbond sheds often land between $350–$700 per m² installed, depending on wind rating, height, insulation and drainage. Get a fixed quote for your site.

What colours work best?

Lighter Colorbond roofs (Surfmist, Shale Grey) reflect heat; walls can go darker (Monument, Basalt). Mixing tones is a popular choice in Perth and Melbourne suburbs.

Are there maintenance tips for coastal sites?

Rinse salt monthly, fit gutter guards, and manage swarf. Choose marine‑grade fasteners and seal cut edges. Keep soil and mulch off wall sheets.
