Shed Costings Tool & Ultimate Guide to Warehouse Construction Cost in Australia

Pricing Tool & Ultimate Guide to Warehouse Costs NSW

So.. What’s it going to cost to build a Warehouse in NSW? Or What’s it going to cost to build a Shed / Awning / Walkway / Covered Outdoor Learning Area?

This is an important question that’s often hard to get any indication on when planning your projects, which is why we’ve built this handy tool for you to be able to get an indication of what it costs.

Fair word of caution – construction is not straight-forward and we’d advise talking to our team to get a quotation rather than relying on this if you’re going to be purchasing a block of land or investing seriously in a project, because there are a lot of things to consider including whether you are even allowed to build what you want on the site you’re looking at – it’s very advisable to get our team to do a due diligence report on your project prior to just committing funds based on an online tool.

There is also a more comprehensive listing of costings / things to consider in our “ultimate guide” below the costing tool – to view the guide, click the “+” button on the expanding section at the bottom of the page.

We trust this tool gives you a indication and helps you on your journey of your new build!

Warehouse & Shed Construction Costs in Australia

If you’re planning a warehouse, shed, COLA or awning, the first question is usually “roughly what will this cost?” We think you should have a starting point, so here are broad budget ranges based on projects we’ve delivered across NSW and regional Australia.

This is only a general guide to assist your planning, not a quote or offer. Your actual price may fall outside these ranges.

Cost guide

2026 · ex GST

Typical rates for a metropolitan or near-metro site with steel wall cladding.

Building type	What’s typically included	Rough guide*
Open structureRural / industrial	Roof-only hay or machinery shed, simple canopy or roof cover	$225 – $500per m²
COLA / shade structureSchool & commercial	School-spec covered outdoor area with footings, gutters, stormwater and linings. Corrugated underlining adds about $300 per m².	$475 – $1,000per m²
Covered walkway	Covered link or walkway, including footings.Walkways cost more per metre because they’re small, follow existing paths and join onto existing buildings, which often needs custom work on site.	$1,000 – $4,000per lineal metre
AwningRoof-only additions	Awning or canopy structure, including retrofit to an existing building.Awnings are complex. As a retrofit, they can trigger council requirements to upgrade the existing building, such as its fire systems, which can quickly add cost. Sprinklers, lighting and bird-proofing under the awning are often needed too. Talk to us for details.	$600 – $800per m²plus $30,000 prelims
WarehouseShell only, installed, no slab	Steel frame, roof and wall cladding and doors, supplied and erected, plus project management, cranes, equipment hire and site supervision	$300 – $725per m²

Warehouse turnkeyDesign & construct	Warehouse with slab & siteworks, plus offices, services and amenities. Offices are typically $1,200 – $2,000 per m² of office area, and services & amenities $100 – $300 per m² of warehouse, on top of the warehouse. Excludes pre-construction and council costs (see below).	$925 – $2,500+per m²

*A general guide only, ex GST. Smaller structures usually cost more per m² than larger ones. These ranges don’t account for your building’s size, shape, height, wind rating, soil, site access, council requirements, material choices or market changes.

Pre-construction & council costs

Design, engineering, council approvals and certification are separate from construction. As a share of the project, they’re highest on small projects.

Project value	Typical pre-construction / council costs	Typical %
$100k – $250kSmall, e.g. awning, carport, small extension	$30,000 – $80,000	25% – 40%
$250k – $1MMid-size, e.g. workshop, mezzanine, medium shed	$60,000 – $150,000	10% – 20%
$1M – $5MLarge commercial / industrial	$80,000 – $400,000+	6% – 10%
$5M+Major projects	$200,000 – $1M+	4% – 8%

External works

Priced by what your site needs.

Compacted gravel hardstand or access road	$25 – $55per m²
Asphalt pavement or car park	$60 – $125per m²
Drained industrial concrete hardstand	$280 – $320per m²
Stormwater drainagePits, pipes, connection	$13,000 – $70,000+per site
On-site detention tankIf council requires one	$25,000 – $135,000+
Security fencing and gates	$80 – $180per metre

Site location

Adjustment to the rates above.

Metropolitan or near-metroWithin about an hour’s drive of a capital city or major centre	Base rate
RegionalCountry towns and regional centres, a few hours from a capital city	+ 5 – 10%
RemoteIsolated sites far from major centres, such as mines, stations and outback towns	+ 20 – 40%+

Remote sites often cost the most because of crew travel and accommodation, freight, crane and hire mobilisation, and longer programmes. Capital cities can have higher supply and compliance costs, but on most projects the logistics of a remote site outweigh them.

What affects the cost of your building?

Size and shape

Larger buildings usually cost less per square metre. Small structures, irregular shapes, long clear spans and tall buildings cost more.

Height and span

As a building gets taller or wider, the frame gets heavier. We recommend structural steel for spans over 12 metres and insist on it over 18 metres.

Location

Distance from major centres drives travel, accommodation, freight and hire costs.

Site conditions

Sloping ground, rock, poor soil, asbestos, underground services, demolition, access limits and working around live operations or occupied schools all add time and cost.

Council and compliance

Some councils restrict materials. For example, reflective finishes aren’t allowed under flight paths. Work on existing buildings can trigger upgrades such as fire systems, and school projects must meet education department specifications.

How you’ll use it

Heavy vehicle traffic, sprinklers, bird-proofing, insulation and specialised services all add to the cost.

Materials

Colorbond® and Zincalume® cladding are the most economical options. Precast concrete costs more but gives better fire resistance, durability and security.
