In this case, the sum is more than the parts – and the building footprint tells only half of the story. Push a button and things begin to unfold, revealing not just a deck but a lofted sleeping area and other pop-out amenities all hiding in the shell of a conventional cargo shipping container.

While it has evolved through various concepts and prototypes, the primary features of the Port-a-Bach cargo container home include “a fully enclosed exterior steel shell (when folded up), appointed with large internal storage cupboards and shelves / stainless steel kitchen and fittings / bathroom with open shower, sink, composting toilet. Fabric screen system gives the versatility of creating rooms within the large open living space: includes bunk beds, double bed room, dressing room, kitchen and bathroom.”

Outside, an “exterior canvas screen system allows to shelter the deck area for comfortable indoor/outdoor flow and living. 6 concrete footings form a stable, non-invasive ‘foundation’, allowing you to situate the unit on a wide range of ground conditions.”

Its mobility and significant flexibility of use are perhaps its key selling points, as well as its durability: close it down and lock it up when not in use and it can withstand the elements, as cargo containers were made to do.
