Display villages, estate launches and regional sales pads don’t always sit still. The office that worked on stage one shouldn’t become a white elephant when the campaign shifts two kilometres down the road.
That’s why buyers search portable sales office, relocatable office and demountable building — not just “container office.” At Container Build Group we build those portable modules in South Lismore: off-grid display suites for sites without power, and compact 20 ft offices you can transport again when the land sales move on.
Portable sales display office — off-grid by design
Our Portable Sales Display Office is published as a portable, custom-built, off-grid, modular sales office with a proper showcasing space. Off-grid solar is part of the brief — useful when the sales pad is ahead of the power pole, or when you want a clean sustainable story on a new estate.
Published program on that page:
- 10-day factory build
- 5-day installation
- Delivery Australia-wide, including Sydney, Melbourne, Brisbane, Perth and Adelaide
For developers selling new investment lots, it’s meant to look like a destination — not a hired donga with a vinyl banner. Deck, glass and branding do the greeting; the module stays relocatable when the next release opens.

Off-grid 20ft office — compact, transportable, self-contained
Need something smaller or more site-shed practical, still finished properly? Our Off Grid Office publishes as a 6 m × 2.4 m (14.4 SQM) unit on a new 20 ft high cube — kitchenette, bathroom, electrical fit-out, and external off-grid kit including high-flow pressure pump, custom 160 L water tank, 160 L sewage holding tank and macerator pump. Off-grid solar packages are available via our solar page as noted there.
That’s the demountable / transportable end of the range: a complete little office you can place on gravel, run for the project, then move.
Published fit-out highlights from that page (spec block):
- Insulation: 50 mm EPS wall and ceiling
- Floor: vinyl plank; bathroom coved vinyl
- Electrical: smoke alarm, fit-out, 4 double power points, 3 LED downlights, internal sub-board, external junction box
- Kitchen: laminate bench, cabinetry, stainless kick, double sink, swivel mixer
- Bathroom: dual-flush toilet, small vanity
- Openings: 2 × 1200 × 1500 mm sliding windows, obscured bathroom window, 2 × 820 mm external doors
- Structure note: reinforced 100 × 50 × 2 mm window and door cut-outs on a new 20 ft high cube
Additional options and finishes are available — we custom-build these cabins the same way we build residential modules.

Transportable by design — including rail
Shipping containers are published on that page as a cost-effective building to transport. We supply nationwide and hold a rail licence, so a unit can move to your closest rail depot where that saves money versus road-only haulage. The off-grid office page publishes example rail figures (e.g. Brisbane–Sydney / Brisbane–Melbourne examples versus typical road costs on the same corridors) — ask us for a door-to-door quote for your site; don’t treat brochure examples as a fixed quote.
That’s the practical difference between a transportable / relocatable owned module and a hire demountable that only ever travels on someone else’s truck schedule.
Who uses a portable sales or display office
From the portable sales page and how commercial buyers brief us:
- Display villages and estate launches — a branded off-grid suite where power isn’t ready yet
- New investment lots — a showcase space that helps buyers decide on-site
- Regional or remote pads — where conventional services are thin or absent
- Campaigns that move — stage one sales office becomes stage two’s office without buying a second building
If the brief is a larger glass-fronted sales suite that will sit longer on one pad, the dual Container Sales Office – x2 40FT is the sibling product — covered in our separate shipping container offices piece. This article stays on the portable / relocatable / demountable end.
Why portable / relocatable / demountable language matters
Hire fleets and “demountable” catalogues own a lot of search traffic. We’re not pretending to be a national hire yard. We manufacture the building:
- Portable — designed to arrive as a module
- Transportable — shipping-container strength; we also publish rail-licence transport options on the off-grid office page (with example rail pricing vs road)
- Relocatable / demountable — when the campaign or site office brief ends, the asset can move with you instead of becoming scrap
Commercial buyers comparing site offices and camps should also skim the commercial hub and mining & government pages for how we talk about Australian-made, one-piece delivery.
FAQ
What’s the build time for the portable sales display office?
Published: 10 days in the factory, 5 days install.
Can it run without mains power?
Yes — the portable sales office is an off-grid solar design. The 20 ft off-grid office lists tanks, pumps and solar package options.
Is this the same as hiring a demountable?
No — we factory-build custom modules in Lismore. Hire fleets are a different product. Ours is an owned, branded sales or site asset you can relocate.
Do you deliver interstate?
Yes — portable sales office page lists major capitals; off-grid office page discusses nationwide supply and rail transport options.
Get a portable office scoped
Send the site constraint (power / no power), how long the campaign runs, and whether the unit must move later. We’ll recommend the display suite or the compact 20 ft off-grid office — or point you to the dual sales office if you need more floor area.
