From definition to design to council permits, Haven Design & Approve makes your shed project simple, legal, and built to last.
Whether you need somewhere to store the mower, house your tools, or finally give yourself the personal retreat you've been planning for years, a shed is one of the smartest investments you can make on your property. But before the first panel goes up, there's something even smarter you need to do: understand what a shed is, what size is right for you, and how to get it properly approved.
Haven Design & Approve is here to walk you through every step.
What Is a Shed? The Definitive Answer
This seems like an obvious question, but it matters enormously from a planning and approvals perspective. A shed is legally and functionally distinct from a garage, granny flat, or habitable outbuilding and that distinction determines which rules apply to your project.
Definition:
A non-habitable outbuilding used for storage, gardening, or as a workshop
Constructed from lightweight materials, typically steel (Colorbond/Zincalume) or timber framing
Detached from the main dwelling and not connected to the primary living structure
Not designed or approved for habitation, sleeping, or permanent occupation
Subject to different planning and building rules than homes, garages, or granny flats
Because a shed is non-habitable, councils typically apply a lighter regulatory touch, but that does not mean permits are optional. Size, site location, and intended use all determine exactly what approvals you need.
Size Matters & Bigger Is Almost Always Better
One of the most common regrets we hear from shed owners?
"I wish I'd built it bigger."
Storage needs grow.
Hobbies expand.
Equipment multiplies.
The lawnmower that fits today shares space tomorrow with a ride-on, a kayak, a trailer, and a workbench that seemed like a great idea at the weekend market.
When planning your shed, think not just about what you need now, but what you'll need in three, five, or ten years. A slightly larger footprint costs proportionally less than you'd expect, and the functional gains are significant.
Storage Sheds
Great from 3×3m, but 6×9m gives you genuine flexibility for vehicles, tools, and seasonal gear.
Workshop Sheds
Allow for bench space, tool storage, and circulation. 6×12m is the sweet spot for serious tradies or hobbyists.
Multipurpose Sheds
Combine storage, workspace, and recreation. Sizing up is especially important when a mezzanine is planned.
Don't Forget the Mezzanine
A mezzanine floor is one of the most powerful ways to dramatically increase your shed's usable area without expanding its footprint. By adding a structural intermediate level, which is typically accessed by a fixed staircase or ladder, you can effectively double your storage or create a dedicated upper-level workspace, studio, or lounge area.
However, it's important to know: any shed with a mezzanine will almost certainly require a building permit, regardless of the ground-floor footprint. The additional structural loads, floor area, and access requirements bring a mezzanine shed into permit territory in virtually all Australian jurisdictions. Haven Design & Approve specialises in designing mezzanine sheds that are fully compliant, structurally engineered, council-ready, and built to last.
Do You Need a Permit to Build a Shed?
The short answer: very often, yes. The exact threshold varies by state and local council, but here is a general guide to how size and use affect your permit obligations:
Shed Size (Approx.) | Typical Permit Requirement | Status |
Under 10m² (e.g. 3×3m) | Often exempt, but check with your council | Likely Exempt |
10–20m² (e.g. 4×5m) | Building permit often required; planning may not be | Always Required |
Over 20m² (e.g. 6×9m+) | Building permit required; planning approval likely | Always Required |
Any size with mezzanine | Building permit required regardless of footprint | Always Required |
Man Cave or She Shed? The Minister of Recreation Demands Approval
Important Notice: Domestic Policy. Consult the Minister of Recreation & Fun Early
Every household has one. They may not have an official title, but their approval is non-negotiable.
When planning your man cave, she shed, hobby studio, or personal sanctuary, the Minister of Recreation & Fun must be included in the process from the very beginning, ideally before the building surveyor is even contacted.
Their sign-off on layout, aesthetics, and designated zones of peace and quiet is every bit as important as the building permit.
With over 4000 building permits completed, we feel pretty confident that we know everything you need to know about building a shed and getting it approved.
Haven Design & Approve strongly recommends a joint consultation here.
In all seriousness, if your shed is intended to serve as a man cave, she shed, creative studio, home gym, or recreational retreat, the same permit rules apply & there are a few additional considerations worth flagging:
A shed used primarily for recreation rather than storage sits in a nuanced space. Councils want to know it remains non-habitable (no bedrooms, bathrooms, or permanent cooking facilities). That said, a bar fridge, a big screen, a bathroom and a seriously comfortable couch?
Entirely within the spirit of a well-designed, permit-approved shed. Your recreational goals are valid. We'll make sure the paperwork matches.
