A COLORBOND® shed or garage in Adelaide typically costs from around $5,000 for a basic storage shed to $50,000 or more for a large garage or workshop in 2026. As a rough guide, a single garage often sits around $5,000–$10,000 and a double garage around $10,000–$25,000, before extras like a concrete slab, electrical work and council approval. Size, height, doors, site preparation and approvals make the biggest difference to the final price. This guide breaks down what drives shed and garage costs in 2026, so you can budget with confidence.

What affects the cost of a shed or garage?
Size and height
Floor area is the biggest driver. Going from a single to a double garage roughly doubles the steel, roofing and slab. Extra wall height — for a caravan, boat or car hoist — adds steel and engineering too.
Engineering and wind rating
Every shed and garage needs to be engineered for its site. Most of Adelaide sits in a lower wind region, but exposed hilltop, coastal and open rural sites can need a heavier frame and stronger fixings, which adds cost.
Doors, windows and openings
Roller doors, personal access doors and windows all add to the price. Wider or taller roller doors cost more, and more openings mean more framing.
Concrete slab and site preparation
Many quotes don’t include the slab, so check before you compare. Adelaide’s reactive clay soils can call for a thicker slab or deeper footings, and sloping blocks — common in the Adelaide Hills — may need cut-and-fill or a retaining wall. Tight access for machinery can also add time and cost.
Council approval
Many sheds and garages in South Australia need development approval through PlanSA. Some small outbuildings can be exempt, depending on size, height, distance from boundaries and your zone. Approval adds drawings, engineering and lodgement fees, so it’s worth factoring in early.
Electrical, insulation and finishes
Power, lighting, insulation, whirlybirds and guttering all add to the total. Planning these at the quote stage is usually cheaper than adding them later.
Garden shed vs garage vs workshop — which do you need?
- Garden or storage shed — for tools, bikes and garden gear. Smallest footprint and lowest cost.
- Single or double garage — secure, weatherproof parking plus storage. Sized around your vehicles.
- Workshop or man cave — extra space, power and lighting for hobbies or a home business.
- Caravan, boat or rural shed — extra height and width for larger vehicles, machinery or farm use.
If you only need cover for a car rather than a fully enclosed space, a carport can be a lower-cost option. See our Carport Cost Adelaide: 2026 Price Guide.
Kit shed vs a shed built for you — what you’re really paying for
A shed kit can look cheaper on paper, but the kit price usually doesn’t include the slab, delivery, installation, engineering for your site or council approval. Once you add those up, the gap often narrows. A supply-and-install builder handles the design, approvals, slab and build, and is responsible for getting it right.
How to keep your shed or garage on budget
- Stick to standard sizes where you can — custom spans and heights cost more.
- Plan power, lighting and insulation at the quote stage.
- Ask whether the slab, approvals and site works are included in every quote you compare.
- Check access for delivery and machinery before you choose a location.
- Choose your COLORBOND® colours early so the design can be finalised without delays.

Frequently asked questions
A COLORBOND® double garage of around 6m × 6m typically costs about $10,000–$25,000 in 2026. The final price depends on height, doors, the slab, site preparation and whether you need council approval.
