I feel that this is the future for architecture in the modern world. Too many people, not enough space, so designing and building space saving and off-grid shelters would be a fantastic way to get architecture to the masses. I know this has already been done, using shipping containers etc. But it could be really developed further into a common form of housing for the next generations, who will not be able to afford to climb onto the property ladder.
