What is a single garage?
A single garage is a one-bay, steel-framed garage built to house a single vehicle, with optional workshop space across the back wall or down one side. It is the most common garage build in Australia for tight blocks, secondary buildings on rural properties, and homeowners who only need one undercover space. Most single garages run between 18 and 36 square metres, sit on a 100mm reinforced concrete slab, and use 100% Australian-made BlueScope steel framing with Colorbond® cladding.
ShedDesigner gives you the shell, the door, and any add-ons (PA door, windows, lean-to, mezzanine). Pick the closest single-garage template, drag your dimensions, drop in your roller door, and submit your design once for free comparable quotes from ShedSafe accredited dealers in your region.
Single garage sizes and door specs
Sizing a single garage starts with your car, not the slab. Get the bay right and the rest follows.
Standard single bay (3.0m x 6.0m). Suits sedans, hatchbacks, and most small SUVs with room to walk around the bonnet and open both doors. Australian Standard AS/NZS 2890.1 sets the minimum off-street parking bay at 2.4m wide x 5.4m long, but real-world garages are sized larger so you can actually open the doors and store gear on the side wall.
Oversized single (3.6m x 6.5m). Suits dual-cab utes, mid-size 4WDs, and any car you want to store with a workbench down one side. The extra 600mm of width is the difference between sliding past the wing mirror and turning sideways every time.
Single with workshop (3.6m x 9.0m or larger). Single-bay door at the front, workshop bay across the back. Common for tradies, hobbyists, and anyone restoring a car. Add a personal access door on the side wall, a window over the bench, and the layout works the same as a small commercial workshop.
Door height. A 2.1m roller door clears most sedans. A 2.4m door clears utes and small 4WDs with roof racks. Bullbar and snorkel clearance pushes the door height to 2.7m on bigger 4WDs. Match the door spec to your tallest vehicle, not your average.
Slab, footings and council
Three things to settle before you sign.
Slab. A standard single-garage slab is 100mm reinforced concrete on a properly compacted base, designed and footing-detailed under AS 2870 Residential slabs and footings. Edge thickening and footing depth scale with the soil class on your block. Your dealer's engineer specifies the detail in the quote.
Wind region. Garages sit on the same wind region map as every other steel building in Australia. AS/NZS 1170.2 splits the country into Regions A through D, with Region B further split into B1 and B2. Coastal and cyclonic zones need heavier framing and tighter purlin spacing. Your dealer engineers to the actual region for your block.
Council. Most Australian councils class a single garage as Class 10a (non-habitable outbuilding) under the National Construction Code. Many states allow single garages under set thresholds (often 20 to 50 square metres, with setback and height conditions) as exempt or complying development. Larger or street-facing builds need full development approval. Always check with your local council before pouring the slab.
Before you get quotes
A garage is the cheapest building you will put on your block, and the one most often built poorly because it is "just a garage."

Frequently Asked Questions
What's the standard size of a single garage in Australia?
Most Australian single garages run from 3.0m wide x 6.0m long for a standard sedan, up to 3.6m wide x 6.5m long for a dual-cab ute or 4WD. The Australian Standard AS/NZS 2890.1 sets a minimum off-street parking bay of 2.4m x 5.4m, but real-world garages are sized larger so you can open the doors and store gear down one wall. Pick the size from your largest vehicle, not your current one.
How much does a single garage cost in Australia?
Most Colorbond® single garage builds in Australia sit between $8,000 and $25,000 supplied and installed, depending on size, door spec, slab, wind region and any extras like windows or a PA door. Slab and concrete usually account for 25 to 35% of the total.
What thickness should the slab be in a single garage?
A standard single-garage slab is 100mm of reinforced concrete on a compacted base, designed under AS 2870 *Residential slabs and footings*. Edge thickening and footing depth scale with your soil class (M, H1, H2 or E in most residential zones). Your dealer's engineer specifies the detail and the bar size in the quote so the slab is sized to your block, not a generic spec.
Do I need council approval for a single garage?
It depends on your state, council and zone. Many councils allow single garages under a set floor area (often 20 to 50 square metres) and height threshold as exempt or complying development. Larger garages, street-facing builds, or garages in heritage or environmental overlays usually need full development approval. Always check with your local council before pouring the slab.
What roller door height do I need for a single garage?
A 2.1m roller door clears most sedans and hatchbacks. A 2.4m door clears utes and most small 4WDs with roof racks. A 2.7m door clears larger 4WDs with bullbars and snorkels, and most caravans. Spec the door height for your tallest vehicle, not your average, and add 100mm of headroom for the door track.
Can I add a workshop bay to a single garage?
Yes. The most common workshop add-on is to extend the garage length by 3 to 4 metres at the back wall and add a personal-access door on the side. You get one undercover bay for the car and a separate workshop bay for the bench, tools and storage. Spec it at the design stage so the slab and footings are sized in one pour.
Can a single garage be insulated?
Yes. The most common upgrade is reflective foil sarking under the roof sheets and wall girts, which reduces summer heat gain. For garages doubling as a workshop or hobby space, a fibreglass batt or polyester batt insulation behind internal lining gets you closer to a habitable interior comfort level. Insulation is added at build, not retrofit.
What's the difference between a single garage and a carport?
A single garage is fully walled and lockable, with a roller door at the front and a slab. A carport is open on at least one side, often two, with no door. A garage protects the car from theft, weather and UV. A carport only protects from rain, sun and bird droppings. Carports are typically 30 to 50% cheaper to build than a comparable single garage.
