Whether you own a hobby farm, manage an agricultural business, or need storage space for machinery, livestock, or vehicles, a large shed is a smart long-term investment. But if you’re wondering how to build a large shed, it’s not as simple as pouring a slab and assembling steel. It takes proper planning, permits, and the right materials to get the job done properly.
Let’s get into everything you need to know to build a large shed.
The Benefits of a Large Shed
A large shed offers more than just space for storage. When built with premium materials like structural steel and RHS frames, large sheds are incredibly durable and require very little maintenance.
Large sheds also have the benefit of being completely tailor-made and flexible – you can design yours from scratch and customise the layout, roofing, doors, and more to suit your needs best. Overall, it’s a versatile use of your land and can be used for a wide range of applications:
➤ Agriculture: Great for protecting valuable equipment, hay, machinery, or even acting as a shelter for livestock.
➤ Commercial: Perfect for workshops, warehouses, or heavy machinery storage.
➤ Personal use: Ideal for a spacious garage or hobby workshop.
Large Shed Designs
The design of a large shed is more than just choosing a structure. It’s about tailoring it to your exact requirements. Whether you need an agricultural shed or large farm sheds, some key features to consider include:
Roof Style
➤ Gable roof: Two sloping sides meeting at a central ridge – classic and functional.
➤ Skillion roof: A single sloping surface, also called mono-pitch, giving a modern look.
➤ Gambrel roof: A two-sided style with multiple slopes, maximising overhead storage space.
Access Points
➤ Roller doors: Ideal for large equipment access, available in manual or motorised options.
➤ Sliding doors: Save space and work well in areas with limited clearance.
➤ Personal access doors: Convenient entry without opening large doors – great for energy efficiency and security.
Materials
Material choice plays a huge role in how long your shed will last and how well it performs. Structural steel with RHS (Rectangular Hollow Section) framing is perfect for large sheds due to its superior strength, load capacity, and resistance to warping. It’s far more durable than cheaper C-section alternatives.
For cladding, Colorbond or Zincalume steel offer excellent weather protection. High-quality fasteners and finishes ensure the structure stays secure and low-maintenance. Investing in the right materials upfront saves you from costly repairs later.
Permits: What You Need to Know
Before construction begins, you’ll need a mandatory building permit. This ensures your shed complies with local building codes and must be overseen by a registered builder and building surveyor.
At Trusteel, we’re registered builders and can guide you through the entire process. We manage permits, provide drawings, documentation, and can even recommend a trusted building surveyor. Whether you want full support or just some expert help, we make it simple to get your project moving.
A planning permit may also be required in specific cases – for example, if your shed exceeds a certain size, is close to property boundaries, or is in a heritage or environmentally sensitive zone.
It’s best to check with your local council. If needed, Trusteel can handle this step, preparing drawings and submitting all paperwork to keep the process smooth.
How Much Does it Cost to Build a Large Shed?
The cost of building a large shed depends on size, materials, design complexity, and site conditions. As a guide:
➤ Basic large shed: starts from $50,000
➤ Premium customised design: from $70,000+
These are estimates; the final cost depends on your specific needs.
