We built a music studio out of shipping containers

Our specialist container modification engineers can do amazing things with shipping containers! Watch as they convert two 40 foot high-cube containers into an awesome music studio and rehearsal space. This step by step video will give you a good idea of what's involved in a high quality container conversion.

We are container modification experts

If you can dream it up - we can build it!

Container modification and customisation can be as simple as adding doors and windows, or as complex as building fully fitted out housing units, portable bars and medical clinics. If you can dream it up, and you've got the budget, our team of container engineers can turn your ideas into a reality.

We're really proud of this area of our business and the projects we've completed, and we'd love to hear from you about your container modification project. Let's build cool things together!

Container modification ideas

Here are some examples of common container modifications:



Add 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 original container doors for extra security.


Side opening access options

Full side opening doors can be built from scratch and fitted to the side of your container, giving you much easier access for un/loading.



Add a recessed door with seals

A recessed access door with weather seals or flashings can be added. This is a common feature of portable office and smoko room conversions.

Rust repair and repaint 

We can repair rust and holes and repaint your container as well as add company logos or advertising onto your container. Check out the paint colour options here.


Security bars and lock-boxes

Boxman can add a lockbox and other security features to protect your container for minimal additional cost.

Add windows and openings

To add natural light and views, windows are easy to fit into a container, and are surprisingly cost effective.


Toilets, sinks and showers

We can add plumbing to your modified container so you can fit anything from a sink to a full bathroom with a shower. We can also build portable toilet and shower blocks.

Custom shelves and cupboards

We can build anything from a few shelves, to comprehensive storage solutions, cupboards, seating and mobile workshop facilities.

Convert a shipping container into a portable office building

The options vary from simply fitting 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. Naturally, the cost also varies with the specification, and is likely to range from $5K for a very basic model to $20K and sometimes more for a full high-end office fit out.
