The Ultimate Guide to Extending Your Shed

Sometime down the track, almost everyone who owns a shed finds that they need a bit more space. Whether you’re looking to store more tools, create a workshop, or simply declutter your existing space, extending your shed is often the perfect solution. At Matrix Steel, we specialise in providing high-quality Australian made steel sheds and extension kits. This guide will walk you through everything you need to know about extending your shed, ensuring you get a result that’s robust, functional, and downright impressive.

Why Extend Your Shed?

Increased Storage

One of the most common reasons for extending a shed is simply to create more room. You’d be surprised at how quickly space can run out once you start accumulating tools, equipment, or even gardening supplies. Extending your shed offers a better way to organise everything efficiently.


A shed extension can evolve your basic storage space into a functional area. Whether you dream of a man cave, a workshop, or even a mini studio, extending your shed makes it possible to tailor the space to suit your needs.

Added Property Value

A larger, high-quality shed can add significant value to your property. Prospective buyers will always appreciate additional functional spaces, making a shed extension a sound investment.

What You Need to Get Started

Planning and Permits

First things first, you’ll need to do a bit of homework. Depending on where you live, you might need council approval to extend your shed. Check with your local council regarding any regulations or requirements. A bit of planning now can save plenty of headaches later.

For example, local councils may have specific setback rules, height restrictions, and maximum allowed square footage for shed structures. Failing to adhere to these can result in fines or having to dismantle the extension. Always check these regulations and secure any necessary permits before proceeding.

Choosing the Right Kit

Shed extension kits are a lifesaver. Not only do they come with all the materials you need, but they also ensure your extension blends seamlessly with your existing structure. At Matrix Steel, our shed extension kits are designed for ease of assembly and maximum durability. Each kit includes pre-measured steel panels, connectors, and all necessary hardware, saving you endless trips to the hardware store.

Step-by-Step Guide to Extending Your Shed

Step 1: Assess Your Current Shed

Before you start, take a good look at your current shed. Is it in good condition? Are there any repairs needed before you begin the extension? It’s crucial to start with a solid foundation. Look for signs of wear and tear like rust, rot, or structural weaknesses in the existing structure.

Step 2: Planning Your Extension

Measure the area where you plan to extend your shed. Ensure there’s enough space for the new structure and that it won’t interfere with any other buildings or boundaries. Accurate measurements mean you’ll purchase the right amount of materials and avoid costly mistakes.

  • Layout: Decide the layout and design of your shed extension. Will it be a simple linear extension, or will you add a new side section? A linear extension might be simpler to execute, while a side addition could offer a more versatile space.
  • Purpose: Consider what you’ll be using the extra space for, as this will guide your design choices. A workshop may require different features compared to a storage extension. For example, a workshop might need electrical outlets, insulation, and extra ventilation.

Step 3: Foundation Work

A strong foundation is key to a durable shed. Depending on your shed’s design, you may need to lay a concrete slab or ensure your existing foundation can support the new structure. If you’re unsure about the foundation requirements, consult with professionals—cutting corners here can lead to long-term problems.

Step 4: Installing the Frame

The frame is the skeleton of your shed extension. You might be tempted to go the DIY route here, but professional installation brings a range of benefits. Our skilled team at Matrix Steel ensures everything is squared, level, and compliant with local building codes, giving you peace of mind. They have the expertise and tools to get the job done quickly and accurately.

Step 5: Adding the Walls and Roof

Once the frame is up, the walls and roof follow. Our steel panels are not just robust and durable but also quick to install. The best part? Steel is termite-proof, fire-resistant and designed to withstand Aussie weather conditions, making it a far superior choice than timber. Unlike timber, steel doesn’t warp or crack, ensuring your shed remains structurally sound for longer.

Step 6: Doors and Windows

Depending on your plan, you’ll need to install doors and possibly windows. Positioning is crucial for ensuring easy access and proper ventilation. Sliding doors might save space, while skylights could be an excellent addition for natural lighting.

Step 7: Finishing Touches

After the major construction, you can add the finer details. Think about shelving, workbenches, storage units, and even power outlets if needed. Insulation and ventilation systems can make your shed a more comfortable and usable space year-round. Your new shed extension is now ready to use!

Benefits of Professional Installation

While DIY projects can be rewarding, there are significant advantages to opting for professional installation:

Quality Assurance

Our professional installation services ensure your shed extension is constructed to the highest standards. You won’t have to worry about short-cuts or structural issues down the line.

Compliance and Safety

We ensure that all construction work meets local building codes and safety regulations. This is something that’s often overlooked in DIY projects but is essential for your safety and peace of mind.

Time Efficiency

A professional team can complete the job more quickly than if you were to tackle it yourself. At Matrix Steel, we’re efficient without compromising on quality.

Why Choose Steel Over Timber?

If you’re comparing materials, steel is the clear winner over timber for several reasons:

  • Durability: Steel is incredibly strong and will last for decades without warping, splitting, or cracking.
  • Low Maintenance: Unlike timber, steel doesn’t require regular treatment and is resistant to pests and rot.
  • Fire Resistance: Steel is non-combustible, adding an extra layer of safety to your shed.
  • Eco-Friendly: Steel is recyclable, making it a more sustainable choice compared to timber.
  • Termite Resistant: Termites can wreak havoc on timber structures in Australia. Choosing steel completely eliminates this risk.

Common Pitfalls and How to Avoid Them

Inadequate Planning

Skipping the planning phase can lead to costly mistakes. Ensure you have a clear plan and have considered all aspects of the build before you start. A detailed plan should include measurements, materials lists, and a timeline.

Ignoring Local Regulations

Not getting the necessary permits can result in fines or having to undo all your hard work. Always check with your local council before starting. Regulations can vary significantly between areas, so it’s essential to get it right.

Cutting Corners on Materials

Opting for cheaper materials might save you money in the short term, but it often leads to problems down the road. Always choose high-quality materials, like our premium steel products at Matrix Steel. Investing in quality upfront can save you from costly repairs and replacements later.

Poor Ventilation

Especially if you’re converting part of your shed into a workspace, ventilation is crucial. Plan for windows, vents, or even fans to ensure proper airflow. Poor ventilation can lead to moisture build-up, which can damage your items and create an uncomfortable environment.

Real-Life Example: Transforming a Shed into a Home Office

To give you an idea of what’s possible, let’s look at an example. One of our clients recently extended their shed to create a home office. Initially, their 3×3 metre shed was used for garden tools and storage. With our help, they extended it by an additional 3 metres, adding custom windows for natural light and insulation for year-round comfort. The result? A stylish and functional home office that allowed them to work from the comfort of their own garden, adding both value and utility to their property.

By following this guide and choosing top-notch materials and professional services, you’ll be well on your way to creating a practical, stylish, and long-lasting shed extension. So go on, make the most of your outdoor space with Matrix Steel!
