The architect meets Chris and Jodie, who are turning a broken-down camper into a cross between a mini HGV and a caravan. A couple reinvent a broken railway carriage as a rustic retreat, and for their observatory, George and Will Hardie learn how to take photos with a beer can.

George looks back at arguably his most ambitious project, when he and Will Hardie built a 360-degree, gravity-defying, rotating home inspired by vintage sci-fi comics. In search of inspiration for this seemingly impossible challenge, George goes to Holland, Germany and the local fairground.
