The link is currently invalid, but I distinctly recall an outdoor toilet in the diagram. Why is land ownership relevant to the posting? If they're told to pick up and move, they can do so very easily. Or, a benevolent land owner (government, commercial, other) could offer them space at low or no cost, particularly if they're willing to live in something such as this, rather than a typical dwelling for the area.
