Mistake #1: Not Checking Local Council Regulations

One of the biggest blunders Aussies make is assuming they can install a shed without council approval. Depending on your location in Perth, you may need a permit—especially if your shed exceeds certain size limits.

How to avoid this:

• Check with your local council (e.g., City of Perth) for specific shed regulations.
• Generally, sheds under 10m² may not need approval, but rules vary.
• Factor in setback requirements from fences and boundaries.

Mistake #2: Choosing the Wrong Size

Many buyers underestimate their storage needs, leading to cramped sheds that quickly become cluttered. On the flip side, an oversized shed wastes space and money.

Pro tip: Measure your current storage items and add 20% for future needs. For example:

Intended Use	Recommended Size
Small garden tools	3m x 2m
Lawnmower + bikes	3m x 4m
Workshop + storage	6m x 4m or larger

Mistake #3: Ignoring Material Quality

Not all sheds are created equal. Cheap, thin steel or untreated timber may save money upfront but will cost you in repairs down the track.

Best materials for Perth’s climate:

• Colorbond steel: Resists rust, termites, and harsh sun.
• Galvanised steel: Budget-friendly but durable.
• Treated pine: Good for wooden sheds but requires maintenance.

At Western Sheds, we use high-quality Australian-made materials to ensure longevity.

Mistake #4: Overlooking Site Preparation

A poorly prepared base leads to uneven floors, water pooling, and even structural damage. Here’s how to prep your site:

• Clear the area: Remove grass, rocks, and debris.
• Level the ground: Use a spirit level for accuracy.
• Choose the right base: Concrete slabs are best for permanent sheds, while compacted gravel works for smaller ones.

Mistake #5: Skipping Professional Installation

DIY shed kits might seem cost-effective, but improper assembly can weaken the structure. Professional installers ensure:

• Correct alignment and secure anchoring.
• Proper sealing against Perth’s occasional heavy rains.
• Warranty compliance (some warranties void if self-installed).

Mistake #6: Forgetting About Ventilation & Insulation

Perth summers can turn sheds into ovens without proper airflow. Consider:

• Whirlybirds or vents: Reduce heat buildup.
• Insulation: Helps regulate temperature if using the shed as a workspace.
• Windows: Allow natural light and cross-ventilation.

FAQs About Buying Sheds in Perth

1. Do I need council approval for a shed in Perth?

It depends on the size and location. Smaller sheds (under 10m²) often don’t need approval, but always check with your local council.

2. What’s the best shed material for Perth’s weather?

Colorbond steel is ideal—it’s durable, rust-resistant, and handles Perth’s UV exposure well.

3. How long does a quality shed last?

With proper maintenance, a steel shed can last 20+ years, while timber sheds may need more upkeep.

4. Can I install a shed myself?

Yes, but professional installation ensures structural integrity and warranty validity. If unsure, hire experts like Western Sheds.

Final Thoughts

Buying a shed is a significant decision, and avoiding these common mistakes will save you time, money, and headaches. Whether you’re in Perth or elsewhere in Australia, always prioritise quality, compliance, and proper planning.
