Konbuild is has just launched an expandable shipping container home that you can order directly from mainland China. Their website is a little scare on information at the moment, so I'm looking forward to seeing it updated. I'm a huge fan of tiny homes and container homes. So it's good to see such an affordable solution come to the market. As an Australian we call these granny flats.
It's pretty neat how it all folds up and expands. I'm sure this will save a lot on shipping. You'll still need to build your own foundation first though.
This is their standard Oslo version.
Their latest model now comes with a clading and a small gable roof.
