Cost of a Shed Slab in Melbourne
A shed slab is a smaller project, but the same genuine cost factors apply — here’s what actually affects the price.
Size Relative to Fixed Costs
Shed slabs, being relatively small, often carry a higher cost per square metre than larger slabs, since fixed costs like site setup and mobilisation are spread over less total area. This is worth understanding when a shed slab quote seems high relative to a per-square-metre figure you might have seen quoted for a much larger project.
Thickness for Intended Use
As covered in our shed slabs guide, thickness and reinforcement depend on intended use — a light garden shed needs less than a workshop with heavy equipment or vehicle storage, so being clear about your plans affects both accurate pricing and getting a slab that actually suits your needs.
Site Access
Backyard shed locations often have more restricted access than a driveway or front-of-house project — narrow side gates, established landscaping to work around — which can affect cost through equipment limitations or additional labour required to work in a constrained space.
Site Preparation Needs
Any excavation, clearing or levelling needed before the slab itself can be poured adds to the total cost — a backyard location that’s never been built on before may need more preparation than one that’s already relatively level and clear.
Getting an Accurate Quote
Being clear about your shed’s exact dimensions, intended use, and any known access challenges helps ensure an accurate quote. We assess every shed slab project in person, since even a small project benefits from proper site assessment rather than a rough estimate over the phone.

Frequently Asked Questions
Why does a shed slab sometimes cost more per square metre than a house slab?
Fixed costs like site setup are spread over a smaller total area, which can make the per-square-metre cost of a smaller slab appear higher than a larger project.
Does a workshop shed cost more than a garden shed slab?
Generally yes, reflecting the additional thickness and reinforcement needed for heavier equipment or vehicle use.
Does backyard access affect shed slab pricing?
Yes — restricted access (narrow gates, established landscaping) can add cost through equipment limitations or additional labour.
Is site preparation included in a shed slab quote?
This should be confirmed explicitly — some backyard locations need more preparation than others, which affects overall project cost.
What should I have ready before requesting a shed slab quote?
Your shed’s exact dimensions, intended use, and awareness of any site access challenges to help ensure an accurate quote.
