The answer depends on much more than the size of your vehicle.The right shed should suit your current lifestyle while giving you flexibility for the future.
At Steeline, every shed is custom designed to suit your property, needs and location. Rather than choosing from standard sizes, you can create a shed that’s practical, functional and built to last.
Before looking at dimensions, think about what your shed needs to do.
Ask yourself:
Many people begin by planning for today’s needs, only to discover they’ve outgrown their shed within a few years.
A little extra space now can save a lot of frustration later.
While every Steeline shed is custom made, these examples provide a useful starting point.
| Typical Use | Common Size |
|---|---|
| Single garage | 3m x 6m |
| Double garage | 6m x 6m |
| Triple garage | 9m x 6m |
| Double garage with workshop | 6m x 9m |
These aren’t fixed rules. They’re simply examples that help you begin planning.
Modern vehicles are often wider and longer than many people expect, especially dual-cab utes and large SUVs. If you also want shelving, bicycles, camping gear, a workbench or room to comfortably walk around your vehicles, it’s worth allowing additional space.
A shed should be practical to use every day, not just large enough to close the roller door.
A shed is often much more than a place to keep vehicles. It can become a workshop, gym, hobby space or weekend retreat.
If you’re planning to add a pool table, exercise equipment, a workbench or seating area, consider the space needed to comfortably use it.
Designing around how you’ll actually use your shed will help create a much more functional space.
For many Australians, the shed becomes the place where projects happen.
Whether you enjoy woodworking, restoring vehicles, gardening or DIY, having a dedicated workspace makes all the difference.
Instead of squeezing a workbench beside your car, consider adding extra width or length to create a practical workshop area. Many customers find that extra workspace is one of the best decisions they make.
Shed height is one of the most important – and often overlooked – considerations.
A standard garage may be suitable for your current vehicle, but what happen if you later buy:
Extra height can also provide valuable overhead storage for items such as kayaks, ladders, roof pods and seasonal equipment.
Planning for additional height now can prevent costly modifications later.
One of the most common things shed owners say is:
“I wish we’d built it a little bigger.”
Your needs can change over time. You may buy a caravan, upgrade your vehicle, take up a new hobby or need additional storage.
Building with some extra capacity gives you flexibility and ensures your shed continues to work for you for years to come.
For larger blocks and acreage, a shed often needs to accommodate more than cars.
You may need space for:
Multiple roller doors and drive-through access can make it easier to store and manoeuvre larger vehicles and machinery.
Farm sheds are rarely one-size-fits-all. The right design depends on your property, equipment and future plans.
When planning a machinery shed, consider:
Our experienced team can help design a shed that suits both your property and the conditions at your location.
Sometimes the biggest limitation isn’t your budget. It’s your block.
Before deciding on shed size, consider:
A slightly different layout may allow you to build a much more practical shed.
Unlike off-the-shelf sheds, every Steeline shed is made to order.
That means you can customise:
Whether you need a compact suburban garage or a large rural machinery shed, Steeline can design a solution to suit your needs.
Every Steeline shed is engineered for its location using specialised design software and is backed by ShedSafe accreditation.
We use premium Australian-made BlueScope steel products including COLORBOND® steel, ZINCALUME® steel and Galvaspan® steel to ensure your shed is built for Australian conditions.
Your shed is also manufactured by your local Steeline branch, supporting Australian manufacturing while giving you access to local expertise and advice.
Choosing the right shed isn’t just about measurements – it’s about understanding how you’ll use the space now and into the future.
Whether you’re replacing an old garage, building a workshop or planning a large machinery shed, Steeline can help design a shed tailored to your property, needs and budget.
The right shed should still be the right shed 10 years from now.
A common single garage size is around 3 metres wide by 6 metres long. However, larger vehicles or additional storage may require extra width or length.
A typical double garage measures around 6 metres by 6 metres. Many homeowners choose a larger design if they want workshop space or additional storage.
If your budget and property allow, building slightly larger than your current needs can provide valuable flexibility for future vehicles, hobbies and storage.
The required height depends on your caravan, including roof-mounted accessories such as air conditioners or solar panels. It’s important to measure your caravan carefully and allow additional clearance for safe access.
