George Clarke's Amazing Spaces

The first episode visits a canal boat conversion in Dudley and a cattle trailer in Yorkshire being turned into a luxury holiday camper. There's also a dynamic, multi-coloured open plan space in Japan. And the idea of building a nostalgic toy treehouse is hatched.

George meets an old friend in Norfolk who sees the potential in the most unpromising of spaces - an old sewage works. With no plans, no budget and just 'brute force and ignorance' - Reuben's audacious idea to create a unique chill out space for his family, including a self-supporting dome roof and a circular carp pond, could be the most incredible Amazing Space ever. George also travels over 5,000 miles exploring Japan. This week features a breathtaking chapel made of intertwining concrete ribbons, where bride and groom tie the knot in the heavens. In the Midlands, a father and daughter work together on salvaging a dilapidated childhood tree house with a budget of just £300. And George and Will continue building a giant toy tree house, and are inspired by a modern tree pavilion. They set about figuring out a way to bring George's impossible childhood fantasy to life using the most unlikely of vegetables.

George meets airline enthusiast Vince, who bought a cockpit from a passenger jet for a bargain £750. He's hired precision engineer Stu to transform it into a summerhouse. However, the two have never met, neither of them have even seen the cockpit and Vince isn't even sure if It'll fit in his garden. It could be facing a turbulent experience for everyone. Sometimes, the most incredible spaces are made with materials destined for the scrap yard. But for Scott, the humble scaffold board is an inspiration for an incredible indoor/outdoor space with moveable walls. George's journey through Japan continues and he visits a multi-coloured apartment in Tokyo. Every corner of the space, including the echo chamber and lunar landscape floor is designed to challenge the mind, the body and hopefully extend your life.

Many people dream of escaping the rat race and living a life of freedom on the road. And that's exactly what communications manager Ellie has done. Ellie bought herself a 1970s double-decker bus, with her heart set on turning it into a luxury mobile home. In Suffolk, Neil Stebbings is looking to create a multi-purpose super den complete with an incredible floor that turns into a roof terrace and a concealed pool table. In Japan, renowned for its stunning court yards, George visits a concrete shrimp shell with a glorious indoor haven featuring soaring bamboo. And George heads to Kew Gardens, looking for some inspiration for his tree-house project.

George meets Dai Saunders, who has a plan to lure his kids away from their gadgets and mobile devices by getting them to help build a spectacular, camouflaged crafting workshop at the end of the garden. In Derbyshire, aspiring 14-year-old architect Fran wants to create her own hangout den in an old horsebox - using birthday money and savings. In Tokyo, one of the most densely populated cities in the world, George visits a tiny house that's actually pretty big. And George and Will visit the Sussex countryside and a tree-house like no other that hovers among the trees.

On the sunny coast of Cornwall, world-class adaptive surfer Pegleg plans a unique extension to his VW campervan, transforming his home on wheels by building a new cabin from scratch. In Pembrokeshire, Martin and Carol-Anne have an out-of-this-world scheme to turn a dome used to house an electricity generator at the London Olympics into an extra-terrestrial glamping pod in the garden. On the coast of western Japan, George visits an earthquake-resistant house made from glass. And George looks at aluminium panels as a new kind of leafy canopy for his and Will Hardie's spectacular tree house.

In Gloucestershire, two young artists are converting an old district library van into a mobile home and art studio. Also, Steve and Marie have found a bunker from World War Two under their garden and are turning it into an office, with an ingenious motorised lift to bring light into the space. In Japan, George visits a town that recycles 80% of all waste, including a pub where everything is recycled, from the windows to the beer itself. And George and Will's incredible supersized tree house is ready to be installed on site.

A London tailor hopes to fashion a work studio in his garden - creating a space where he'll be proud to welcome his clients. In Bristol, an enterprising team are building a cabin in a crane 150 feet off the ground, to raise money for Friends of the Earth. In Japan, George visits a capsule hotel in central Tokyo and a sleep pod measuring only two metres deep and one metre wide. He also visits a traditional bath house. And finally, as the latest series concludes, George's childhood dream comes true as the super-sized toy tree house is completed.

Architect George Clarke and master craftsman Will Hardie travel to Norway, to discover how a country with some of the harshest weather on the planet has become a leader in small space design. Norwegian craftsmanship and determination puts the country at the forefront of global architecture. George travels by husky sled to a tree house in a forest that can withstand nine tonnes of snowfall and gale force winds. There's also a visit to an ice hotel - the mother of all igloos, complete with 30 rooms, a bar, and even a snow chapel. The boys meet members of the local Sami community, to see the moveable home that has kept members of their community safe for hundreds of years. There's a disused oil silo turned into a circular home; a geodesic aluminium dome; and an epic family home in the mountains. And Will meets leading explorer Borge Ousland.

In this 24 hour special, George Clarke takes on the 600-year-old legend of the Ty Unnos - a piece of Welsh folklore that claims that if you can build a house with four walls, a roof, and have a fire burning in your hearth in less than a day, then that house and the ground beneath it is yours. George recruits Will Hardie and a crack team of highly skilled former Amazing Spaces builders. Together they design a stunning lakeside cabin built using the natural raw materials to be found in the surrounding lakes, hills and valleys near Machynlleth in Wales. The team have just two days to complete all preparations for this epic challenge. And when the big day comes, so does the wild and stormy weather. Soon enough, George and the team find themselves soaking wet, in the pitch dark, with a monumental build to complete by sunrise.

George looks back over some of the best off-grid projects from Amazing Spaces: from a wooden yurt in a Devonshire quarry, to a medieval summerhouse in a suburban Kent garden made out of cob. George also sees the stunning results of a VW campervan restoration in Shropshire and visits a Victorian shepherds hut in Worcester.

There's a doghouse in Devon being converted into an extension. There's also the ex-cop launching a cream tea business in a camper van.
