Strength and Security

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.

We 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:
- 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.
- 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!

On a Tight Budget?
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.
