George Clarke shows how to turn small spaces into big dreams. In the first episode, George meets the couple who have invested their life savings in the hope of converting a wreck of a bus into a holiday let. He also sees how an old underground toilet has been transformed into a stunning apartment and how a horsebox has been given a new lease of life as a family holiday home.

George meets a teacher creating a bolt-hole in the Lake District by following an increasingly popular trend in the UK of buying his own plot of countryside and doing the building himself.

George Clarke heads to Scotland to meet farmers Julie and George Nicholson who take an enormous financial risk and commission local designer Sam Booth to build an innovative prototype module holiday home. The stakes are high, though, as the couple have invested their entire savings of £30,000 on a design that's never been tested before. George also takes a trip to Bournemouth to see a beach hut.

George meets Ruth Tidd, who is attempting to turn an old caravan that was once used as a home for chickens into an ice cream parlour. He also follows the building of the country's first ever tree tent and is lucky enough to get to try it out, as well as getting the chance to visit some very unique offices built from four old tube carriages.

George meets a man who drunkenly bought a 1920s showman's carriage on eBay, but quickly sobered up when he saw the poor condition it was in. He visits a holiday home constructed from an old World War II vehicle and follows the build of Britain's most landlocked beach hut, based in Birmingham. Later, there's a major setback with his own project to create an ultra-modern holiday home out of a 1970s caravan.

It's the last episode of the series, and George is finally ready to unveil his own small space project. Having bought a 1970s caravan for just £300, George and his team have spent months turning it into an extraordinary holiday home for him and his family, including a bespoke kitchen, a wood burning stove, innovative bedrooms, and a beautiful deck. Has it all been worth it?
