Need Portable Buildings for Hire? Here’s What to Know Before You Book

Whether you're running a busy construction site in Brisbane, managing a remote mining operation, or coordinating a large outdoor event across Queensland and Northern-NSW, one thing's clear - you need functional, comfortable space, and you need it fast. That's where portable buildings for hire come in.

At Flexihire, we've been supplying portable buildings to worksites and events across Queensland for over 40 years. This guide covers everything you need to know before you book - from the types of structures available, to sizes, use cases, and how to choose the right option for your project.

What Are Portable Buildings?

Portable buildings - also known as demountable or transportable buildings - are prefabricated structures designed to be moved rather than fixed permanently to a site. They are typically transported on a large trailer and positioned using a crane.

Unlike permanent construction, portable buildings can be set up quickly, relocated as project needs change, and returned once the job is done. They offer the comfort and functionality of a fixed structure without the long-term commitment.

Types of Portable Buildings Available for Hire

Dongas

Dongas are modular, transportable buildings widely used as workers accommodation on job sites and as demountable classrooms. If your project involves remote or long-duration works where crew need to sleep and rest on site, dongas are the go-to solution.

Flexihire's dongas are well-maintained and delivered directly to your site, with setup and removal handled by our experienced team.

Modular Office Cabins

Need a quiet, insulated space for administration, planning, or site management? Modular office cabins provide a professional work environment away from the noise and activity of the main site. They can be fitted out with desks, power, lighting, and air conditioning to keep your team productive.

Flexihire's modular cabins come with built-in crane lifting points, making relocation straightforward as your project evolves.

Transportable Buildings - General Purpose

Beyond accommodation and offices, transportable buildings can be configured as lunchrooms, first-aid stations, site amenities, or storage and staging areas for outdoor events. Their flexibility makes them suitable for a wide range of industries - construction, resources, agriculture, education, and events.

Portable Building Sizes - What's Available?

Flexihire offers portable buildings in four standard sizes to accommodate different site footprints and staff numbers:

• 3m x 3m - Compact solution for small sites or single-person offices
• 6m x 3m - Suits small teams or dual-purpose office/lunchroom setups
• 9m x 3m and 9.6m x 3m - Mid-range option for growing crews
• 12m x 3m - Full-size solution for larger teams or multi-function site facilities

Not sure which size suits your project? Speak with your local Flexihire branch - our team can assess your site size, staff numbers, and requirements to recommend the right fit.

What Can You Use a Hired Portable Building For?

Portable buildings are incredibly versatile. Common uses across Brisbane and Queensland and Northern-NSW include:

• Site offices on construction and civil projects
• Lunchrooms and break facilities for site crews
• Workers accommodation (dongas) on remote or long-duration projects
• Demountable classrooms for schools or training facilities
• First-aid and welfare stations at events and outdoor festivals
• Temporary office space during building renovations or relocations

Portable Buildings vs Mobile Site Office Trailers - What’s the Difference?

A common question we get is: what's the difference between a portable building and a mobile office trailer?

A mobile office trailer is an all-in-one site office solution - typically towable and often including toilet facilities within the unit. It's a good choice when you need a comprehensive single-unit solution and have towing capability.

A portable building, by contrast, is positioned by crane rather than towed, and is generally larger and more customisable. It's the better option when you need a more permanent-feeling setup, more interior space, or multiple separate structures across a large site.

Frequently Asked Questions

How quickly can a portable building be delivered and set up?

Delivery and setup times vary depending on your location and site access, but most portable buildings can be delivered and positioned within one to two business days of booking. Contact your local Flexihire branch early to confirm lead times, especially for larger or multi-unit projects.

Do I need council approval to place a portable building on my site?

In many cases, temporary portable buildings used on active construction or event sites do not require council approval, particularly for short-term use. However, requirements vary by council and intended use. It's always best to check with your local authority before placement.

Can portable buildings be connected to power and plumbing?

Yes. Portable buildings can be connected to site power and, depending on the fit-out, plumbing for amenities. Flexihire's buildings can be optioned with a range of accessories - speak with your branch about what services are available and what site connections you'll need to arrange.

What's the minimum hire period for a portable building?

Minimum hire periods vary depending on the unit and your location. Flexihire offers flexible hire terms to suit both short-term events and long-duration construction or accommodation projects. Contact your local branch for specific pricing and minimum terms.

Can multiple portable buildings be joined together to create a larger space?

Modular portable buildings are designed to work as standalone units, but multiple units can be positioned side by side on a site to create a larger combined facility. For larger projects requiring integrated multi-unit setups, speak with Flexihire's Project Capability team who can advise on the best configuration for your needs.
