Why 5.7m Has Become the Industry Benchmark
When it comes to portable offices for construction sites and temporary workspaces, one size has consistently emerged as the industry favourite: the 5.7-metre configuration. This isn’t a coincidence. The 5.7m portable office hits the sweet spot between usable internal floor space, transport efficiency, and site footprint — making it the go-to choice for project managers, site supervisors, and events coordinators across Australia.
In this guide, we break down exactly why the 5.7m office trailer dominates the market, what you get inside, and how to determine if it’s the right fit for your project.
What’s Inside a 5.7m Portable Office?
A standard 5.7m portable office trailer delivers approximately 18–20 square metres of internal floor space — enough to comfortably accommodate:
- 4–6 workstations with full desk and chair setup
- A site manager’s private desk area
- Filing storage and plan storage
- Air conditioning (reverse-cycle, both heating and cooling)
- Kitchenette with sink and bench space
- 240V power with multiple GPO outlets
- LED lighting throughout
- Windows for natural light and cross-ventilation
Transport Efficiency: The Hidden Advantage
The 5.7m length is specifically designed to move via standard B-double or semi-trailer without requiring a pilot vehicle or oversize load permit in most Australian states. This dramatically reduces relocation costs — a critical factor for construction projects that move across multiple sites over their lifecycle.
Compare this to 6.0m+ configurations, which often trigger wide load restrictions and require police escorts in certain states. The 5.7m sits just inside the standard envelope, giving you near-maximum space without the logistical overhead.
Optimal Space Utilisation for Construction Sites
Construction sites have constrained footprints. Laydown areas, crane exclusion zones, and traffic management corridors limit where welfare facilities can be placed. The 5.7m office trailer fits neatly into a standard car park space (with a small tail swing allowance), making it deployable in locations where larger structures would be impossible.
The Scanvogn 5.7m office trailer — one of the configurations we supply — features a well-thought-out internal layout with the entry door positioned to minimise wind exposure and allow for tandem deployment alongside amenities blocks or crew trailers.
5.7m vs 4.2m vs 3.2m: Which Should You Choose?
| Size | Floor Area | Best For | Team Size |
|---|---|---|---|
| 3.2m | ~10 m² | Single supervisor, checkpoints | 1–2 people |
| 4.2m | ~13 m² | Small site offices, foreman’s offices | 2–4 people |
| 5.7m | ~18 m² | Main site office, project management | 4–6 people |
Who Uses 5.7m Portable Offices?
The 5.7m configuration is favoured across a wide range of industries:
- Construction companies — as the primary site office for project administration
- Mining operations — for exploration camps and remote site management
- Government and council — temporary offices for road works and infrastructure projects
- Events companies — as event management and ticketing offices
- Agricultural operations — seasonal harvest management offices
