When you’re investing in a new shed, you’re not just buying storage—you’re adding long-term value to your property. Whether it’s for tools, garden gear, a workshop, or extra household space, a shed is something you expect to last for years. But many homeowners in Western Australia discover—often too late—that a few simple mistakes can lead to wasted money, council hassles, or a shed that simply doesn’t do the job.
This guide helps you avoid the most common pitfalls when choosing a shed in WA, especially if you’ve never installed one before.
Why Avoiding Buying Mistakes Matters
A shed might look like a simple structure, but the wrong decision can affect:
- How long the shed lasts in WA weather
- Whether the council approves your installation
- How easy it is to maintain
- Whether the space actually meets your needs
- The resale appeal of your property
With the right preparation, you can avoid costly errors and choose a shed built to handle WA’s unique climate and lifestyle.
Common Buying Mistakes to Avoid
1. Choosing a Shed Without Considering WA Weather Conditions
Western Australia can be harsh on structures. Intense sun, coastal salt, heavy winds, and occasional storms all take a toll.
What often goes wrong
- People choose thin metal sheeting that buckles in heat.
- Coastal homeowners buy untreated steel that corrodes quickly.
- Sheds are installed without considering wind ratings.
How to avoid it
- Choose galvanised or Colorbond steel for longevity.
- Ask for the correct wind rating for your suburb.
- If you live near the coast, choose marine-grade protection.
Real-life example:
One homeowner in Rockingham bought a budget 0.3mm steel shed and had to replace panels within a year due to corrosion. Spending a bit more upfront would’ve doubled the lifespan.
2. Underestimating the Size You Actually Need
Many people choose a shed based on today’s needs—not tomorrow’s.
Signs you’re picking a shed that’s too small
- You haven’t accounted for future tools, bikes, or hobby gear.
- You can’t safely move around once items are inside.
- You’re forced to store items outside, defeating the purpose.
A simple sizing rule
Choose a shed at least one size larger than what you think you need.
Helpful size guide
| Purpose | Recommended Size |
| Basic garden tools | 2m x 2m |
| Bikes + mower + tools | 3m x 3m |
| Workshop setup | 4m x 3m or bigger |
| Multi-use storage | 4m x 4m and up |
3. Forgetting to Check Council Requirements
This is one of the biggest mistakes seen across Sheds WA projects. Regulations can vary significantly between suburbs.
Common issues
- Installing a shed without approval
- Placing the shed too close to boundaries
- Overheight structures not meeting rules
- Fines or forced removal of the shed
How to avoid it
- Visit your local council website BEFORE buying
- Ask the shed supplier if they can handle approvals
- Keep a copy of all drawings, permits, and compliance documents
4. Not Preparing the Right Foundation
Even the best shed won’t last long on a poor base.
Mistakes homeowners often make
- Installing sheds on uneven soil
- Skipping a concrete slab
- Poor drainage leading to rust or mould
Best practice
- Use a concrete slab or properly compacted crushed rock
- Keep the slab slightly elevated to prevent flooding
- Ensure you have at least 100mm of proper drainage
5. Buying the Cheapest Shed Available
A cheap shed might save you money today, but will cost more over time.
Pros of budget sheds
- Lower upfront cost
- Good for temporary storage
Cons
- Weak panels
- Poor door quality
- No proper framing
- Short lifespan in WA climate
When comparing suppliers, don’t just look at price. Compare steel thickness, warranty, bracing, wind rating, door strength, coatings, and brand reputation.
6. Skipping Professional Installation
DIY can be tempting, but shed installation requires precision.
Common DIY issues
- Misaligned panels
- Roof leaks
- Loose anchors
- Doors not closing properly
If you’re not confident with tools, hire a professional. It ensures your shed meets structural and safety standards.
A Handy Pre-Purchase Checklist
Before you buy, ask yourself:
- ☐ Is the shed’s steel suitable for WA weather?
- ☐ Does it have the right wind rating for my area?
- ☐ Have I chosen a size that fits future needs?
- ☐ Have I checked council rules and setbacks?
- ☐ Do I have a solid foundation plan?
- ☐ Am I prioritising quality over the cheapest price?
- ☐ Will I use a professional installer?
Ticking all these boxes ensures you choose a shed that lasts.
FAQ: Choosing the Right Shed in WA
In many cases, yes. It depends on size, height, and placement. Always check before purchasing.
Colorbond and galvanised steel are the most durable options, especially for coastal areas.
A high-quality, well-installed shed can last 15–25 years or more.
Timber is attractive but requires more maintenance. Steel is generally better for WA because it doesn’t warp or attract termites.
A minimum of 4m x 3m, but go larger if you use multiple tools or benches.
Conclusion
Choosing a shed is more than picking a structure—it’s planning for durability, practicality, and compliance. By avoiding the most common pitfalls and understanding your needs, you’re far more likely to find a shed that adds real value to your property and lifestyle.
Whether you’re storing garden tools, setting up a workshop, or building extra space, take the time to compare materials, check council rules, and choose a shed built for tough WA conditions.
A smart choice today means fewer headaches tomorrow—so take your time, ask the right questions, and invest in a shed that truly lasts.
