Features

Built for Safety and Compliance
Constructed from heavy-duty marine-grade steel, Royal Wolf offices are engineered for Australia’s harshest worksites. From urban builds to remote high-risk zones, these units help you meet OH&S obligations with confidence. Optional stairs, landings and stacking capabilities ensure safe vertical expansion when space is tight.

Climate-Controlled Comfort
Designed for year-round performance, each office includes full insulation, wall-mounted reverse cycle air conditioning, and weather-sealed doors and windows. These features maintain optimal internal temperatures and reduce external noise, creating a comfortable, focused working environment for your crew.

Secure, Professional Workspace
Steel personnel doors, integrated lock boxes, security mesh, and flyscreened windows deliver robust protection for equipment and documents while ensuring secure access. The interior fit-out includes LED lighting, power outlets, and data provisions, supporting everything from site meetings to admin tasks.

Fast Installation and Easy Relocation
Delivered pre-fitted and ready to use, these offices can be positioned quickly via tilt tray, side loader or crane truck. Their modular design supports stacking or joining with other site units including lunchrooms, change rooms, or first aid rooms, to form a complete, adaptable facility footprint.

20ft Offices FAQs

What is the difference between a portable site office and a standard site shed?

Unlike traditional site sheds, Royal Wolf’s portable site offices are engineered from durable shipping containers, offering superior strength, security, and weather resistance. They’re fully insulated, air-conditioned, and ready for fast relocation across project stages.

Are 20ft and 40ft shipping container offices available for hire or purchase?

Yes, both 20ft and 40ft site offices can be hired for short- or long-term use, or purchased outright. United Rentals provides flexible options to suit your project timeline and budget.

What can I fit inside a 20ft office container?

A 20ft office typically accommodates up to 3–4 people for desk-based work, complete with power, lighting, air conditioning, and secure entry. It’s ideal for planning meetings or as a supervisor’s workspace on mid-size sites.

Can I stack or join multiple portable site offices together?

Absolutely. Royal Wolf’s shipping container offices are designed to stack or join with other units, including lunchrooms and first aid rooms, to create modular, multi-level site compounds.

How quickly can a 40ft site office be delivered and installed?

Most 40ft site offices are delivered and operational within days, depending on site access and location. With tilt tray, side loader, or crane delivery options, installation is quick and disruption-free.
