George Clarke's Amazing Spaces

George meets a couple planning to transform a tiny 1960s ambulance into a campervan where the family of six can cook, eat and sleep.

George visits an apartment inspired by a beehive, a cocktail bar made out of a dilapidated Land Rover and a real life UFO suspended in the trees at a tree hotel in a Swedish forest.

George meets a carpenter hoping to turn a double decker bus into a holiday retreat, and a couple who have quit their jobs and thrown their life savings into designing a boat hotel.

George meets a woman who wants to build a shop and mobile home out of an old horsebox, but she only has £500 to spend.

George visits a futuristic living space at YO! Home, where the double bed rises up out of the floor and into the ceiling, and the kitchen and bathrooms are cleverly hidden from view.

George is invited onboard a blinged-up double-decker bus that's been converted into a posh restaurant and bar. He meets a couple living in a railway station and sees their plans for the waiting room.

George catches up with designer Max McMurdo, who is making a classroom out of two rusting shipping containers. And there's also a garden office and a beauty emporium run from a rare 1947 caravan.

George prepares to unveil his own small-space project, an ambitious, accessible, multi-functional tree house within the Calvert Trust, an outward bound activities centre for families with disabilities.

In this festive special, George visits a stalactite crystal grotto in Surrey and a small-spaces enthusiast who has rebuilt a Victorian flat-pack tin chapel in Shropshire
