Shipping container modification and repair is a Boxman specialty

Boxman > Modifications

Container modification and customisation - if you can dream it, we can build it!

Container modification and customisation can be as simple as adding a window or door, painting the container with your company branding, or as complex as building fully fitted out housing units, portable bars and medical clinics.

Ultimately if you can dream it up, and you've got the budget, we can modify and build it. Boxman has a team of engineers focused on turning your ideas into a reality. Container modification is a strength of our business we take great pride in, so please contact us with your container modification ideas.

This page illustrates some simple shipping container modification and customisation options, as well as some of the more complex projects we undertake. To see some of Boxman's branded and sign-written containers and trade show container ideas, please click here.

Container modifications and repairs - some of the basic options

Fit a door or ranch slider

We fit all types of standard doors, ranch sliders or roller doors, all of which can be placed behind the container doors for security.

Full side opening doors

Full side opening doors can be built from scratch and fitted to the side of your container.

Recessed door with seals

A recessed personnel access door with weather seals can be added.

Custom paint colours

We can repair and repaint your container as well as add company branding on new containers. View colour options.


Security bars and lock-boxes

Adding a lock-box to the doors of your container provides extra security at minimal additional cost.

Windows and openings

Windows are relatively easy to fit to a container, and are surprisingly cost effective.

Toilets, sinks and showers

A full bathroom can be added to your container, and we can build portable toilet/shower blocks.

Shelving and cupboards

We can create a basic office unit, and provide shelving, cupboards and workspaces within a mobile workshop.

How to convert a shipping container into a portable office building

The most basic options involve the fitting of windows and doors into an unlined (non-insulated) steel container with no electrical work, all the way up to a fully lined, fully fitted out, air-conditioned office unit. Pricing is entirely dependent upon specification, and likely to range from a very basic $5,000 model, up to $20,000 and sometimes more.
