Portable Office - Shipping Container Offices

What is a portable office container?

A portable office shipping container provides a low-cost, rent free alternative to traditional office buildings. They can be used as either a permanent or temporary place to work from in a wide range of settings: from a home office in the garden to a site office on a construction site, offices for schools, visitor attractions and temporary events. Portable offices are modified with everything you need to get you up and running in a portable office and can be customised with an additional range of features. Choose from used, once-used or new build shipping containers that can be cut to the length that suits you and your budget.

Portable office cabin costs

Containers Direct have long been market leaders in shipping container office and canteen conversions, supplying both trade and customers with bespoke conversions from our specialist workshops. Although shipping container portable offices have always represented good value compared to a traditional build, costs can still be too high for projects with more limited budgets. So to bring down these costs and reduce the selling price, in 2016 we launched the ModiBox range of steel container portable offices that are budget-friendly.

Explore the prices and specification of some standard lengths in the range.

The ModiBox portable office

The strength and security inherent in a shipping container makes it ideal for the structure of a portable office. The ModiBox retains all the benefits of the standard portable office, in terms of strength, portability and security but at a heavily discounted price. The product also allows flexibility in design, in terms of the positioning of anti-vandal doors and windows, choice of exterior colours and interior finishes, giving you the opportunity to create your own bespoke container office within a low price bracket. The unit is delivered to you on a plug in and go basis. If you're in a hurry we always hold in stock standard sizes from the ModiBox range with standard lay-outs, ready for quick dispatch. Depending on the size you require we begin the conversion with a used 20ft shipping container, or a used 40ft shipping container. For other sized offices we cut these down to the size required, with our smallest office manufactured from a 10ft container. If preferred we can also make the ModiBox from new 20ft and new 40ft shipping containers. We also offer the new build portable office, manufactured from scratch in our fabrication department.

Extra Wide Portable Site Offices

Extra wide site officesWe understand that one of the main reasons people can't use a regular shipping container office conversion is due to the uniform width of containers (8ft), which can often be too narrow for an office space. Containers Direct have two solutions to this potential problem:
  1. Using our in-house fabricators, we can build containers from scratch to a variety of widths, most commonly to 10ft wide. Although more expensive, these containers are made using 1.6mm corrugated panels as standard, and are completely customisable to suit your needs. We once built the shell of a new build 35ft x 10ft office conversion for our client at Parkstone Bay Marina, complete with ply lining and insulation, who then completed the office interior on site.

  2. Another way of extending the width of your portable site office container is to join two or more of them together. Our bespoke method of joining containers allows for two or more containers to be joined side by side to provide a greater width for your portable office conversion. This option is great as it allows for much larger spaces to be created, whilst still being portable. The largest joining project completed so far was created by joining four 20ft containers side by side to create a school changing rooms, fitted with toilets, showers and two separate changing rooms!

Flat pack containers

Take a look at our flat pack container offices if you are working to a tight budget, or don't have the space or access to deliver a shipping container. These offices are fully man portable, easy to assemble on site and are modular, so you can join them up together to make whatever size office space you require. Our portable steel booth offers a smaller space for use as a controlled site entry point.

For larger self assembly offices see our CXO range, which includes new CXO Plus Line. These provide excellent options for larger areas of modular office space with a range of options for external panels and interior fittings.
