Hi, we have actually built a luxury 4 bedroom container home from scratch. It had a master bedroom, walk in robe, ensuite, laundry, living area, study, bathroom, toilet, alfrsco etc and ended by being quite large.

We bought existing containers and converted them. As a builder, we understood the challenges of getting it to comply, but as MB has said, the challenges were huge.

The engineering reinforcement and cutting of corten steel with a plasma cutter was a whole new learning curve in practicality.

The realities of dealing with condensation /insulation and wiring are another.

My strong suggestion to you is to either go through a specialist container builder (there is one in Victoria from memory) or use another method.

Here's a piccy of what we did....

I suggest you listen to the Experts above and consider all your options. Designing a layout is the easy part compared with all the practical requirements.

If you stick with the container method, we suggest you put aside a lot of room in your budget for adequate insulation and cooling/heating alternatives! :)

Aside from the expert opinions, I recommend checking out tiny houses for inspiration on layout, there have been some great developments on how to use space, for function and style. Also consider if one will be enough or if it is a build on concept. But otherwise having studied building for the purpose of building own home based on criteria of a no debt build, (which I've done/process of) if you can there are some really great prefab options with great inclusions for budgets, less stress and time. :) Good luck and remember to take plenty of pics and video footage

I believe in flying roofs so no rain or sun on the container, then the steel is naturally cool. I also insulate the outside only so no internal space reduction. I find a cavity works well and wrapping it in roofing foil before fibre cement etc. 125mm grinder and lots of thin blades works best for me.
