Yeah, but whose back garden?

From The Daily Mail:

* Kieran Evans was given keys to 'iKozie' home in Barbourne, Worcester after it was air-lifted into a back garden

*Thee 186sq ft (17.25sq m) space includes bedroom, kitchen, bathroom 'module' and an entertainment zone

* Project, believed to be first of its kind in world, is aimed at solving Britain's homelessness and housing crisis

The article doesn't say. At a guess, it's his parents' back garden and there's more to this than meets the eye.
