Cardboard has long been the stuff of dreams – the joke is that at Christmas children spend less time playing with a toy than with the box it came in. And few things are more exciting than the arrival of a new appliance and a box that can become an instant fortress or playhouse.
The houses are framed and then spun from rolls of cardboard on an armature in a factory. The cardboard is waterproofed, the modules are paneled inside and then shipped to their final location.
This is by no means the first time cardboard has been used as a permanent building material. But it might be one of the most energy efficient ways to build small scale dwellings.
