Site Office Containers for Sale
Portable shipping container offices in 10ft, 20ft & 40ft — prefab, powered and ready to work
What Is a Site Office Container?
A site office container is a shipping container office: a portable, secure, insulated and powered workspace built to go straight to work on site. Every SCS site office is prefabricated on a purpose-built new high cube shell — engineered as an office from day one, not a used cargo box converted after years of freight service. That’s the go-to solution for builders, miners and contractors who need reliable facilities on-site, fast. At SCS Australia, we stock a standard range of Site Office Containers for Sale in 10ft, 20ft and 40ft sizes, delivered Australia-wide.

Shipping & Delivery
SCS Australia delivers container offices Australia-wide:
- NSW: Newcastle, Sydney, Wollongong, Central Coast
- QLD: Brisbane, Gold Coast, Sunshine Coast
- VIC: Melbourne, Geelong
- SA, WA, NT, ACT & TAS also covered.
We also offer crane unload and remote access solutions.
Every shipping container site office keeps its standard container footprint — the air conditioner sits recessed, so nothing protrudes past the corner castings. That means delivery and relocation are routine container movements by tilt tray, side-loader or crane truck, not oversize transport jobs.
Optional Extras
We offer a range of factory-fitted options, specified at order:
- Desks and furniture
- Partitions and shelving
- Security mesh or window bars
- Solar or whirlybird roof vents
- External stairs and access ramps
- Custom painting and branding
Site Office Compliance for Australian Standards
Every SCS site office container is built to work on Australian sites:
- Electrical fit-out to Australian Standards (AS/NZS 3000 Wiring Rules) with RCD safety switches
- Fit-out materials selected to meet National Construction Code (NCC) requirements
- Built on ISO 668 high cube shells — the finished office handles and ships like any other container
- Fully insulated with 50mm EPS panel to walls and ceiling

Frequently Asked Questions – Site Office Containers
What sizes do site office containers come in?
Our standard range covers three sizes: 10ft (~6.7 m², under 3 m long), 20ft (~12 m² — the standard site office for a two-to-three person crew), and 40ft (~26 m² with dual air conditioning). All three share the same insulated, powered fit-out — the difference is floor space.
What's the difference between a container office and a site office?
Nothing — they’re two names for the same product. A site office, container office, shipping container office, mobile office container or portable container office all describe a fitted workspace built into a container shell. Whatever you call it, the unit is insulated, wired, air conditioned and relocatable as standard freight.
