Demountable offices offer flexibility and versatility on sites where permanent constructions aren’t needed. Demountable buildings are a valuable asset in a number of industries where temporary sites are set up, including construction, mining, fieldwork, and more. Demountable buildings are most commonly used as offices, but they can play host to a huge range of facilities, from washing and cooking facilities to overnight accommodation.

If you need temporary office space, a demountable office gives you numerous benefits. They can be supplied and constructed quickly and efficiently – building a permanent office from scratch takes significantly longer and can be much costlier than a demountable space. This means that choosing a demountable office is a more cost-effective solution, and a great option if you’re working to a tight budget.

Another advantage of demountable offices is that they are resilient and low maintenance. This makes them a great addition to construction or industrial sites that require temporary office space. For construction sites where you might need to move the office as the project progresses, a demountable office makes much more sense than building a permanent space because they are durable enough to withstand frequent relocation. As well as being fast and efficient to set up, a demountable office can also easily be dismantled promptly at the end of its use or if it needs to be relocated. Because every part of a demountable structure is removed to be used again elsewhere, there won’t be any additional mess or debris to deal with on your site.


Demountables can be supplied quickly and constructed efficiently; it takes considerably less time to build a demountable than to build one from bricks and mortar, which means that your project can get off the ground sooner. Demountables effectively take the hassle out of providing offices and other facilities for staff onsite, which means your project can go ahead on schedule.


Just like a permanent building, commercial demountables are designed with functionality and comfort in mind. Offices can be fitted with comfortable furnishings, temperature control, electricity, and other facilities to ensure that your staff have everything they need for the duration of your project. And because offices aren’t permanent, each installation can be customised to your exact requirements.


Not sure how long you’ll need an office for? Hire a demountable today and benefit from flexible terms which mean you can have your facilities for as long as you need them, even if your project overruns. Demountable facilities offer the best versatility in the market for projects with uncertain time frames.


For projects where an office building or onsite accommodation is needed for just a few months or even years, the cost of building a permanent office (and potentially then having to demolish it at the end of the project) is prohibitive. Demountables offer a cost-effective solution in these cases, enabling site managers to install comfortable and functional offices and other commercial buildings for the duration of the project without committing to the investment that a permanent building would require.


Just because our offices are transportable, it doesn’t mean they’re any less hard-wearing than regular offices. Built for heavy-duty construction sites and similarly hazardous environments, demountables require little maintenance and upkeep to last years and years. They can withstand frequent relocation, or they can stand firm for years on long-term construction sites and other large scale projects.


Demountables are just as easy to tear down as they are to set up, which means that when your project is reaching its conclusion, removing your temporary offices from the site will be a quick and painless job. Demountables leave little in the way of mess or debris when they’re removed from a site because everything will be carefully disassembled and taken away for future use, which means your site will be left clean and ready for the next stage of your project to commence.

Frequently ASked Questions

What is a demountable office?

A demountable office is a portable office space that is modular in its design. It offers a great deal of flexibility in terms of size, construction and functionality. It’s an excellent option if you require temporary office space or want to save time and money when looking to create an office for your business. These types of spaces are perfect for on-site or off-grid work, as they can be constructed pretty much anywhere you need.

Are demountable offices eco-friendly?

Absolutely. Most demountable office spaces are built using reusable and recyclable materials, which lowers the amount of landfill waste. You don’t have to create new materials with a demountable office, which lowers energy usage. A great deal of the construction happens off-site, which lowers transportation costs and fuel usage. Also, most portable office spaces provide exceptional temperature control which improves energy and running costs.

Does a demountable office have the same facilities as a regular office?

Yes, all of our demountable offices are fully functional and include all the expected utilities you would expect from a standard office space. This includes things like electricity, temperature control and furnishings.

How long does it take to build a site office?

The length of time it takes to build a site office is usually between 7-10 days. There will be variations if access is tricky or if your demountables design and specifications are especially complex. Overall, choosing a demountable office is one of the quickest ways to get a high spec building in a short space of time.

How long do demountable offices last?

A demountable office can last up to 25 years. Simple maintenance like regular painting and cleaning will maximise the life of your building so you can enjoy the optimum use from your investment. But if looking to have a temporary office, you may consider getting second-hand demountables.

What is site accommodation?

Site accommodation offers a space for an office, where all the necessary documents can be stored, and where teams can meet to discuss the job. They can also offer facilities like toilets and kitchens so your site team can take breaks in comfort. Larger site offices can also offer use as a sales space, for residential or commercial projects.
