This episode features some of the youngest small space designers around. In Somerset, 12-year-old Gwynnie wants her own luxury party shed. In south west London, Marcus attempts a boat restoration project with a young woman he's just met internet dating. In North Wales, George revisits a pair of newlyweds who converted an old army truck into a mobile campervan rather than go on honeymoon. And in New Zealand, George visits a sky sphere with a device that delivers chilled beer to your chair.
