A garden shed is more than just a storage solution—it’s a practical and often essential addition to many Australian backyards. Whether you’re an avid gardener, a DIY enthusiast, or simply someone looking to free up space in the garage, a well-constructed garden shed can offer secure, accessible storage for tools, equipment, bikes, and more. With Australia’s diverse climate, from the temperate southern regions to the hot, humid north, a durable and weather-resistant shed can protect your items from the elements year-round.
Beyond functionality, a shed can also enhance the appearance and utility of your outdoor space. Some homeowners use their sheds as mini workshops, potting sheds, or even as quiet backyard retreats. Building your own shed not only allows for personal customisation but can also save money compared to pre-fabricated or professionally built alternatives.
This step-by-step guide will walk you through the DIY process of planning, constructing, and finishing your own garden shed. Whether you’re a seasoned DIYer or a weekend warrior trying something new, these steps will help you create a sturdy, attractive shed that suits your needs and lasts for years to come.
Step 1: Planning Your Shed
Determine the Purpose
Start by identifying how you’ll use your shed. Will it store garden tools, function as a workspace, or house larger items like lawnmowers or bikes? Knowing the purpose will help you decide on the right size, layout, and features such as ventilation, lighting, or built-in storage.
Choosing the Location
Pick a spot with level ground, good drainage, and easy access from the house or garden. Avoid low-lying areas that may flood. Consider sunlight—especially if you’ll work inside the shed or store plants—and ensure there’s enough space around it for maintenance and roof runoff.
Designing the Shed
Design your shed to fit both your practical and aesthetic needs. Decide on dimensions (commonly 2x2m to 3x3m for backyard use), roof style (gable, skillion, or flat), and features like doors, windows, and internal shelving. Draw up simple plans or use a shed design app for guidance.
Step 2: Gathering Materials and Tools
List of Materials
- Foundation: Gravel, concrete blocks, or cement slab
- Framing & Walls: Treated timber, plywood, or external-grade cladding
- Roofing: Corrugated metal sheets or asphalt shingles
- Other Items: Door hardware, hinges, screws, nails, waterproof sealant, paint or stain
Required Tools
- Woodworking Tools: Circular saw, drill, hammer, nail gun
- Measuring Tools: Spirit level, tape measure, framing square
- Safety Equipment: Safety goggles, gloves, dust mask, ear protection
Step 3: Preparing the Site
Clearing the Area
Remove any grass, weeds, roots, or debris from your chosen site. Mark out the perimeter with stakes and string, ensuring there’s enough clearance around the edges for construction.
Leveling the Ground
Use a shovel and rake to level the site. Compact the soil with a tamper or roller for a firm base. If the ground is sloped, consider minor excavation or adding gravel to even it out.
Laying the Foundation
Choose between a gravel bed, concrete pavers, or a full cement slab:
- Gravel/Paver Foundation: Ideal for small sheds, easy to DIY
- Concrete Slab: More durable, best for larger or heavy-duty sheds
Lay your foundation carefully, ensuring it is square, level, and stable.
Step 4: Building the Shed Structure
Constructing the Floor
Build a timber frame using treated joists and fix it to your foundation. Lay floorboards (plywood or decking timber) over the frame and fasten securely. Check all corners with a square and ensure the floor is level.
Building the Walls
Construct wall frames flat on the ground, then lift and fix them in place. Anchor them to the floor frame and to each other at the corners. Add bracing for extra support, and attach your chosen siding—weatherboard, timber panels, or metal cladding.
Installing the Roof
Build the roof frame according to your shed design. Gable roofs are popular for their runoff and storage space. Install rafters, add roof sheets or shingles, and seal with waterproof flashing. Don’t forget roof overhangs to protect the walls from rain.
Step 5: Adding Finishing Touches
Installing Doors and Windows
Choose door styles based on space and use: single for compact sheds, double or sliding for larger access. Fit the door with strong hinges and locks. Position windows to maximise light and airflow, using durable, shatter-resistant glass or polycarbonate panels.
Painting and Staining
Apply exterior-grade paint or timber stain to protect your shed from Australia’s harsh sun and heavy rain. Use at least two coats, and seal any joins with weatherproof caulking.
Organising the Interior
Install shelves, hooks, tool racks, and storage bins to keep everything tidy. Customise your interior layout to suit your storage or workspace needs. Adding a solar light or battery-powered LED fixtures can make your shed functional even after dark.
Building a garden shed can be a rewarding DIY project that boosts your property’s functionality and value. With proper planning, the right tools, and a bit of elbow grease, you can create a backyard shed that stands the test of time and meets your everyday needs. Whether for storing tools, starting seedlings, or simply finding a quiet space to work, your new shed will quickly become one of your home’s most useful assets.
How to build a shed – FAQ
Do you need a permit to build a shed in Australia?
In most parts of Australia, you may need a building permit or council approval to construct a shed—especially if it exceeds a certain size, height, or is close to boundaries. Each state and council has its own regulations. Generally, small sheds under 10m² with no plumbing don’t require approval, but always check with your local council before starting your project.
Is it better to build a shed or buy one?
Building your own shed can be more cost-effective and customisable, allowing you to choose materials and design that fit your needs. However, buying a pre-made shed or a shed kit from Bunnings or Stratco is faster and easier for those without construction experience. The best option depends on your budget, skills, and available time.
Is it legal to live in a shed in Australia?
Living in a shed permanently is generally not legal in Australia unless it meets the same standards as a habitable dwelling. This includes insulation, plumbing, electricity, and council approval. Some rural councils may allow temporary accommodation in a converted shed, but only with a valid permit.
Do Bunnings install sheds?
Yes, Bunnings offers a shed installation service across Australia for many of their shed kits. You can book the service in-store or online. The cost depends on the shed size, foundation type, and site accessibility. Installation includes assembly, anchoring, and ensuring the shed is secure and weatherproof.
How much does a livable shed cost in Australia?
A livable shed—often called a “shed home” or “shouse”—can cost anywhere from $25,000 to over $100,000, depending on size, materials, insulation, plumbing, and finishes. Basic conversions may be cheaper, while fully equipped sheds with kitchens and bathrooms cost more due to building code compliance.
What is the most cost-effective size shed to build?
For most homeowners, a 3m x 3m to 3m x 4.5m shed is the most cost-effective size. It’s large enough for tools, bikes, or a small workshop, yet small enough to avoid permit costs and major foundations. Larger sheds offer better value per square metre but require higher upfront investment.
Do sheds add value to houses?
Yes, sheds can add value to a property, especially if they’re well-built, secure, and functional. Buyers often appreciate extra storage or workshop space. However, the value added depends on the shed’s condition, size, and how well it complements the home and yard.
How much is it to build a shed from scratch?
Building a shed from scratch in Australia typically costs between $800 and $4,000, depending on size, materials, and foundation type. DIY builds are cheaper, especially using timber or steel frame kits, but professional construction or concrete bases can raise costs significantly.
What is the cheapest way to build a shed on a budget?
The cheapest way to build a shed is to use reclaimed materials, a gravel or timber base instead of concrete, and a simple gable roof design. DIY assembly also saves on labour. Buying materials in bulk and avoiding unnecessary features like windows or insulation can further reduce costs.
Is a shed a good investment?
Yes, a shed can be a smart investment. It increases property utility, provides secure storage, and can attract buyers. Whether for hobbies, gardening, or as a home office, a well-built shed offers long-term value and functionality.
How to calculate shed cost?
To estimate your shed cost, calculate total expenses for materials, foundation, roofing, flooring, doors, paint, and labour (if not DIY). Add 10–15% for unexpected costs. Online shed cost calculators or spreadsheets can help you compare different sizes and materials to stay within budget.
