ΔΕΙΤΕ ΤΗ ΚΑΤΑΣΚΕΥΗ ΕΝΟΣ ΔΩΜΑΤΙΟΥ ΑΠΟ ΕΝΑ ΚΟΝΤΕΙΝΕΡ !The Transatron project began with a search for compact and transportable building options.
Having purchased a small vacant block of land I was keen to find an affordable and comfortable solution to make use of the beautiful mountain location and escape the city for weekends and holidays. After a career of building things to be delivered quickly and efficiently in theatre, I began a search for compact and transportable building options. The moment of inspiration came when I saw a container conversion by a New Zealand couple. It was a high end architectural project that made the most of the limited space in a 20ft container, yet opened up to create living space with a minimal impact on the surrounding environment.
Enter the Transatron Project. A personal, once off project to build a compact, transportable and pleasant space for my wife and I to enjoy. With a limited budget and a want to use as much recycled, reclaimed and renewable products we scoured eBay, construction recycling centres and end of run products from shop floors. Some items were sourced new as we wanted to ensure the end product was a comfortable and warm living space that would shelter us from the extremes of the mountain weather.
Starting with a second hand, 20ft, high cube, double pallet wide container we did a thorough clean of the inside to remove any previous contaminates and patched up the paint work. Being one to overdo everything I tackle, this became an ongoing approach to the whole project. It should be noted at this point that I am not a builder or tradesman, so any of the build techniques, tips or images linked to this article are to be taken as a reflection on my experience, not instruction or advice on building or converting a container. But back to the container conversion now…
Cutting the deck opening was a big job.
Cutting out the front panel was a big job. The first thing that occurred was a spring release of the panelling as it was cut from the structure. With the dents and irregularities of the panel along with the gussets it sprang out and became difficult to handle. Once re-cut, shaped and welded to fit into the deck frame it became a lot easier to work with. To reinforce the long opening on the side of the container we fitted a “C” Channel to the roof flat bar. The “C” Channel was also used to mount and support the deck winch, which would need to lift the full weight of the steel frame and timber deck.
The C Channel adds to structural integrity and is used as a mount for the deck winch.
The winch proved a complex fitting and unfortunately ended up being mounted on the roof of the container. The original plan for the winch was to have it mounted in the “C” Channel and internal frame work. On the first test we found that it was creating a large amount of torsional forces on the “C” Channel, to the point that it flexed the front wall. In hindsight I should have mounted the winch to a plate welded to the internal roof of the container and set beside the “C” Channel. But as this was late in the construction process I could not undertake this change and had to make the box on the top to house and secure the 12v winch.
The seal of the door frame in the closed position could have taken many different configurations. I decided to go with an angle bar around the outside edges of the deck to close the gap when closed against the container. As we would be leaving the container on the block of land in a high fire zone I wanted to minimise gaps and spaces for debris, animals and weather. This worked well once the door was under tension from the winch and would be made a tighter seal if a rubber strip was added along the top face above the opening.
Nine deck hinges were used to distribute load, but this may have been overkill.
To attach and hinge the deck we used Goliath Ball Hinges. Avaialble at Bunnings or online these are strong and reliable hinges. We alternated the nine hinges (left and right settings) to locate the door in position. We used nine hinges to distribute the load, but may have gotten away with fewer.
Once the door panel was in place we worked on the internal walls and cladding. Finding suitable, level and consistent fixing points on the walls and frame of the container was problematic. This was due to the dents and discrepancies within the container panels. With some packing material and creative placement we set the wall and ceiling frames. It should be noted that my frame work was dimensioned for the fixing points of the kitchen shelf unit, hence the irregular spacing and, again, over engineering and construction. The walls were clad with Gyprock to maximise the finish of the walls and improve the feel of the space. However, and this is a reoccurring problem with mobile products, the plaster joins were susceptible to cracking whilst in transit.
Polystyrene boards serve as excellent insulation during the heat of summer and retain heat during the winter.
We had hoped to find an appropriate insulation material for the container, but ended up using polystyrene panels cut to fit into the frame work. This provided great insulation during direct sun in summer and retention of heat in the cooler months. To double up on the insulation we used a perforated sarking to assist the reflection of heat from the steel panels.
Before cladding, much of the floor was insulated as well. The floating bamboo flooring adds to the feel of the area, making it seem much less like a metal box.
The internal floor was fixed to the steel deck of the container. This allowed us to insulate and level off the floor as well as line it up with the external deck once in the down position. The internal floor was then clad with a floating bamboo floor with a 15mm panel to ensure the density added to the feel of the room. Once down and the room lined we found we had a very “solid” space, far from the tinnie nature of the container we were converting.
Laying the floating bamboo floor wasn’t a quick job.
Our primary focus was to ensure we maximised the view from one side of the container across the deck and down the block of land. We found some excess window stock from a building site, including the glass sliding door and a pair of windows. We then lucked upon some smaller windows on eBay that worked well for the opposite side. These smaller windows wound out, improving ventilation and adding a little extra light.
The sliding glass door and large windows maximise the view.
To finish off the internal living space I built a plywood shelving unit to fit specific items required for a weekend away. This included space for a sink, commercial esky, gas cooker, water filter, crockery and all those other items that accrue over time. Taking into consideration the requirements for gas storage/use, we anticipated cooking outside, but it would be possible to create an external storage unit for a gas bottle (similar to a caravan) if you wanted to have a more permanent set-up.
The internals feature some basic weekender amenities, such as a sink and space for an Esky.

To heat the space we installed a second hand pot belly stove. This was flued through the roof and fitted into a corner of the room and beneath one of the smaller windows. Beside the pot belly stove is an additional door leading out the original end doors of the container. Our concept was to create a wet area within the footprint of the doors and close it in with a canvas or plastic curtain, making space for a portable toilet and shower. Additional furniture was selected to make the most of the space and double up on functionality where possible. By the end it became an extremely comfortable, solid and inviting space to be in.
Heating is provided by a small pot bellied stove, flued through the roof.
The side door can be used to enclose a “wet area” for an external toilet and shower.
The container was transformed into a solid and inviting place to spend the weekend.
Easily transportable on the back of a truck.
At this point I should let you know about our experience in getting this container onto our land and into use. Prior to construction we investigated the rulings on temporary structures for our local council. Everything we found allowed us to use this container on our block of land, unfortunately, after 12 months of weekend work and shipping the container to our site, we found ourselves with a council that had changed their rulings for structures and use of temporary dwellings on land without a primary dwelling. After going through the process of working with the council as they deciphered their own new rules, we were presented with two options, to submit a DA for a primary dwelling or remove the container. With our limited funds we were forced to remove the container and have since sold it on for other use. A devastating result after investing so much time, energy and money into a low impact solution, but one that only opened up other opportunities and highlighted the good people that helped out in delivering and supporting our project.
