Construction sites, civil jobs and remote pads all need a proper site office — not a dusty tool shed with a folding table. At Container Build Group we build container site offices and portable site offices in our South Lismore factory, then deliver them Australia-wide as complete units ready to place.
If you are searching site office, container site office or portable site office, this page is the practical overview. Product detail and galleries live on the individual project pages linked below.
Container Sales Office x2 40FT — Container sales / site office built from two 40 ft shipping containers — deck, ramp and insulated roofing.
What a container site office is (and when you need one)
A shipping-container site office starts with a steel high-cube shell and becomes a lockable workplace: desks, power, lighting, climate control where specified, and a layout that survives mud, dust and shift changeovers.
Typical uses for CBG site offices include:
- Construction and civil site management rooms
- Developer sales pads and display-village offices (see also our shipping container offices hub)
- Mining and government project offices alongside camp accommodation
- Temporary or relocatable offices when the campaign or pad moves
We factory-build in South Lismore, NSW, with a complete service from design consultation through fabrication and installation liaison. Units are Australian-made and Australian-compliant — not imported flat-packs assembled on the pad.
Configurations and inclusions
These are the office formats we build today:
Container Sales Office — 2 × 40 ft
Our Container Sales Office – x2 40FT is built from two 40 ft shipping containers. Inclusions:
- Large deck and access ramp
- Insulated roofing panels over the containers and deck area
- 60 m² open-plan interior by removing and reinforcing the centre walls
- Custom fixed-panel glass for a clean, professional façade
- Multiple versions of this sales-office format have been built
It works as a site office or sales suite when you need real floor area and a proper arrival experience — not a single narrow donga.

Gallery context includes the Sawtell Commons / Bonville showroom container exterior.

Real commercial projects, factory-built in Lismore
Site offices sit in the same commercial family as our larger delivered projects. On our mining and government infrastructure page we list portable buildings and site offices custom-built in South Lismore alongside projects such as:
- Snowy Hydro 32-man Alpine Lodge — alpine-rated modular lodge
- Port of Brisbane expansion — first three-level supercontainer building on that programme
- Middlemount Golf Club — Queensland commercial rebuild (20 ft & 40 ft containers with cool rooms; completed in 60 days, 30 days ahead of schedule per the project case)
Browse the full commercial projects hub for galleries.
Factory-built in South Lismore, delivered Australia-wide
Every unit leaves 39 Habib Drive, South Lismore NSW 2480. Engineer and certifier factory inspections are part of how we work; buildings arrive as complete modules, not a flat-pack puzzle on a muddy site.
Transport is coordinated to your pad — train or semi-truck depending on the unit and route. Installation pathways are scoped with your builder or our install liaison.

How a site office job usually runs
Most site-office enquiries follow the same practical path we use on other commercial modules:
- Feasibility — site access for containers and crane, power status, and whether the office is temporary or long-term.
- Drafting & engineering — layout, insulation and any off-grid items confirmed with our drafting team.
- Fixed-price fabrication — contract on the agreed specification; fabrication in South Lismore.
- Factory review — photos or a factory visit before remaining payment, where scoped.
- Transport & install — truck or rail to the pad; builder or CBG install pathway completes handover.
That process is the same backbone we use for larger commercial deliveries — from sales suites through to amenities and camp packages — so a site office does not become an orphan product with a different quality bar.
Site office vs portable sales suite — picking the right format
Use this as a quick filter before you call:
- Need open-plan floor area and a client-facing façade? Start with the dual 40 ft sales office (60 m², deck, ramp, glass).
- Pad has no power yet, or the campaign will move? Start with the portable sales display office (off-grid solar; 10-day factory / 5-day install).
- Compact footprint with kitchenette and bathroom? Look at the 20 ft off-grid office (14.4 m²).
- Simple lockable site hut energy? The 20 ft office cabin format on the commercial office page is the lean starting point.
Many jobs combine an office with ablutions or a crib module. We build those companions in the same workshop — see the ablution and mining camp guides linked above.
Why steel-container construction suits Australian sites
Shipping containers are engineered for stacking, transport and harsh environments. We take that structural backbone and turn it into a workplace: insulated, wired and fitted before it leaves Lismore. For dusty civil pads, coastal display villages and remote energy projects, that “arrive complete” approach beats assembling a kit in the weather.
We can build to any cyclone rating up to C4, engineered to suit your site and your certifier’s requirements. Insulation and energy options are set here in Australia because the build happens here — alpine cold through to extreme heat.
Frequently asked questions
What is the difference between a site office and a sales office?
Same steel backbone. A site office prioritises lockable workstations and site practicality; our dual 40 ft format doubles as a sales suite with deck, ramp and glass when presentation matters. We configure from the same factory process either way.
Can a container site office run off-grid?
Yes where specified. Our portable sales display office includes off-grid solar, and the 20 ft off-grid office lists tanks, pump and macerator options on its specs block.
How big is the dual 40 ft office?
Open-plan area is 60 m² after centre-wall removal and reinforcement.
How long does a portable sales office take?
Program: 10 days factory build and 5 days installation (portable sales display office).
Do you deliver outside NSW?
Yes. We deliver Australia-wide from South Lismore, including capital cities. Transport is quoted to your site.
Are your offices Australian-made?
Yes. We design and manufacture in South Lismore. We don’t import finished buildings from China or overseas; components are supplied by Australian companies and manufacturers.
Can you add ablutions or a crib room next to the office?
Yes as a separate module or package. See our ablution and mining camp pages for companion units we already build.
