Gill Heriz has brought together a collection of some of the most incredible small homes, from houseboats on the water, trailers in the countryside, and micro-apartments in the city, to treehouses in the woods. A traditional Mongolian yurt provides off-grid living for a young couple and their baby. A preacher’s wagon offers a chic, flexible space for its owners. There is a reclusive shack set in woodland, homes made from recycled Scotch whisky barrels, and a village of tiny houses for the homeless, all providing comfortable and sustainable accommodation for their pioneering owners.
