Boat enthusiast James Strangeways invites Kevin McCloud to survey progress on the construction of his new home, which his architect nephew Ben Hebblethwaite has designed to be as 'un-houselike' as possible. James has spent the past 35 years travelling the canals and waterways of Britain, and despite never liking houses, has decided now is the time to put down roots on dry land. Ben hoped a home standing on stilts above a marsh, and incorporating ship-like qualities such as a keel-shaped roof, will be enough to satisfy his boat-mad uncle. However, Ben's contractor goes into liquidation a few months into the project, taking �87,000 of the �300,000 budget, and when James decides to make a few tweaks to the design, alarm-bells begin to ring for the young architect.

Kevin McCloud returns to Devon for an update on one of the most inspirational builds he has ever witnessed. Marine Captain Jon White and wife Becky were living happily in a small cottage in Devon when in June 2010, while serving in Afghanistan, Jon stepped on an improvised explosive device. Jon lost both legs and his right arm. Every part of his and Becky's lives had to change - starting with where they could live. Their architect came up with a cutting edge, semi open plan building with a dramatic wing-like-roof; but crucially it was to be without noticeable adaptations for Jon's disabilities. It was an ambitious design, and despite the help of a number of military charities and a capable team of builders, Jon was already under severe pressure to finish the house, when news came that Becky was pregnant. Has the new home proved as enabling for Jon, Becky and their expanding family as they'd hoped?

When Denise Daniel and Doug Ibbs gave up everything in the UK to start a new life in a remote part of central France, they couldn't have known what was ahead of them. Most people would have regretted falling in love with a massive, dilapidated manor house with just four crumbling walls and half a roof, but not Doug and Deni. This impressive, extraordinary and utterly determined couple rolled up their sleeves and slogged away day and night, doing everything themselves, year after year, until slowly but surely they created a magnificent edifice out of the ruins they bought off the internet.

But it's not long before the project becomes bogged down in the logistical challenges of building such a complex design on a small island that is only accessible by a narrow footbridge.

Natasha Cargill wants to build a home shaped like two enormous periscopes in rural Norfolk. But a limited budget and tight planning restrictions start to take their toll. To get planning permission for her build, Natasha Cargill has to ensure not only that the materials used are sustainable, but also agree to measure the amount of diesel used to deliver them. The planning controls are so rigid in fact that even details like the type of portaloos the builders use and the size of her bath have to be monitored. Natasha has just �330k to spend on construction and just six months to complete.

Tracy Fox and husband Steve want to build an 'urban shed' out of industrial materials in an old milk yard in south east London. But the choice of unorthodox materials proves challenging and costly.

Rob Hodgson and Kay Ralph plan to build an architectural monument high on a cliff top. They want to build a sleek glass-fronted house inspired by the cliff-top villas of California. Their plot overlooks a beautiful National Trust beach in North Wales, but to have their jaw-dropping panoramic views will mean taking the biggest gamble of their lives. Access will be incredibly difficult and expensive because of a low bridge over the narrow track to the site. Erosion specialists predict their stunning new home could one day fall into the sea. Prohibited by the local council from reinforcing the cliff face, they decide to build anyway, believing at least the house will outlive them.

Rejecting the coastal sprawl around Malaga they found a virgin plot of land up in the Andalucian hills for just �35,000. But instead of building a home like the traditional old fincas nearby, their architect son's design was a confrontational, modernist glass box, surrounded by boldly coloured connected rooms, hidden behind a giant citadel wall. Construction proved stressful. The couple put all their trust in a local Spanish builder who had never built a house like this before. The local residents didn't like it and the mayor tried to get it re-painted white. But if they could just finish the build, it promised to be the coolest retirement home Kevin McCloud has ever seen.

With the help of their architect friend Zac, they decide not to knock it down, but to radically redesign, remodel and transform this unsightly lump it into a sleek, crisp, modernist masterpiece.

Tamayo Hussey's missed Japan ever since she moved to the UK with her husband Nigel. To stave off the homesickness they've decided to transform a forester's lodge into a Japanese house complete with roof bath, tatami room and sliding paper walls. Keen to keep costs under control, Nigel and Tamayo decide to engage only the design skills of an architect and with no previous building experience they bravely go it alone, working without any detailed drawings and fire-fighting problems every step of the way. The wood they're using for the timber frame - Japanese larch - hasn't been used for building houses before in the UK, so no one can be sure it will be strong enough, the new interior walls don't meet properly and the replacement window design can't cope with the rain. But Nigel and Tamayo are determined to overcome any obstacle to get the Japanese house they're so desperate for.

Kevin meets flying instructor Colin Mackinnon and trapeze artist Marta Briongos and the incredible metal home they're building next to their very own airfield in Strathaven, Scotland. There aren't many people in Britain who can say they own their own airfield. But Colin and Marta Briongos are part of the very select few. The airfield is so important to them, they've decided to live there too. Their ambitious plan is to build an incredible metal sculptural home next to the runway, designed by one of Scotland's most eminent architects and inspired by aircraft hangars. But the difficulties of building their beautiful design soon become apparent. And before the project is barely off the ground they're contending with violent rain, snow, 100-mile-an-hour winds and the worst storms for 100 years. With work slowed down to a snail's pace, what was supposed to be a year-long project heads into its third year.

When he lost three limbs in Afghanistan, Jon's life changed forever. Now he wants to build a house that allows him to live independently. The design is cutting edge, but the budget spirals. Marine captain Jon's life changed forever when he stepped on a land mine. Before his injuries, home for Jon had meant a crooked chocolate box Devon cottage. After countless viewings of uninspiring specialist dwellings and awkward conversions, they realised that the only way to get a house that would enable Jon to live independently was to build it themselves. The design boasts sleek glass walls, open plan spaces and a dramatic wing-like roof. Crucially the design concept is for there to be no noticeable adaptations due to Jon's disabilities. Despite his lack of experience, Jon decides to project manage and calls on the support of a number of military charities for this hugely ambitious project. The pressure to finish on time increases when Becky discovers she is pregnant.

Kevin meets Martin and Kae Walker, who want to build the ultimate family home, inspired by a giant farm shed.

Jonathan Broom and his wife Deborah have put everything on hold while he pursues his dream of building a mini Hollywood Hills-style mansion right in the gritty heart of north London. For ten years Jonathan Broom has been obsessed with building his own home.They finally stumble across a scrap of land right in the gritty heart of North London, but it's fraught with problems, and the only way they can build their wildly ambitious �1million pound family home, complete with nanny flat and swimming pool, is by sinking half of it six metres below ground. It's a project that pushes the couple and their builder to the very limit. Desperate to make every penny of the budget stretch, Jonathan strikes every deal he can, and even sells his business to raise funds. Originally scheduled to take a year, this giant hole in the ground consumes their money and lives for much longer.

Kevin McCloud follows a project to renovate and extend a classic 1920s cinema in Thorne, South Yorkshire. With little knowledge of restoration, Gwyn and Kate boldly set about turning the dilapidated building into a family home using masses of concrete after taking advice from an architect friend. The couple are hoping to create a hydraulic glass wall that opens up one side of the house to form a UV-filtered canopy, and there are also plans for a white roof extension that resembles a diving board.

Kevin McCloud meets artists Indi and Rebecca, who are planning to build a modern, larch-clad home on the Isle of Skye, with a second hand-crafted building alongside to use as their studio, all on a tight budget of �150,000. They have been saving for years, but making it happen will mean taking on the savage weather, not to mention the sceptical locals - and as if that weren't enough, most of the work is being done by one man, local builder Donald.

Kevin McCloud meets Audrey and Jeff, who dream of living in one of west London's most exclusive areas. However, the way they can afford it is to go underground. Their plan is to transform a listed Edwardian artist's studio - along with 5,000 sq ft of derelict basement - into a bespoke subterranean home, complete with supersize kitchen, mezzanine sitting room, four en-suite bedrooms, a gym, cinema, steam room and wine cellar. As if the task weren't tricky enough, they are doing it without proper architect's drawings and Audrey is project managing - and the difficulties begin almost from the start.

Kevin McCloud marks the 100th episode with one of the programme's most ambitious projects to date. Leigh Osborne and Graham Voce want to convert and extend a landmark 150-year-old water tower in central London into a luxury home. Grade II-listed, derelict and with 6ft-thick walls, it's a huge challenge for the pair, who also plan to build two structures at the base - a lift shaft connected by a series of glass tunnels, and a modern living space. The result will be a four-bedroom property over nine floors, complete with a room at the top offering spectacular 360 degree views across the capital. The tower, which is located directly above London Underground's Northern Line, was originally built for Lambeth Workhouse in 1877 and became a Grade II listed building in 2008.

Kevin McCloud follows Lysette and Nigel Offley, who are knocking down an old Thames boathouse and constructing a cutting-edge home in its place. Taking inspiration from the river itself, they have designed a building of waves and curves with a huge glass porthole for a roof light. But problems begin almost from the start, as they can't find a contractor willing to build over the water, their architect leaves unexpectedly and the costs turn out much higher than expected. To make matters worse, the neighbours aren't happy about such a radical sight in their traditional community. As they begin to compromise, Kevin wonders if the couple's dreams will ever be realised.

Mary Martin and Carl Turner want to build a home that resembles a giant stack of glass cubes in Brixton, south London. The couple are hoping the structure will become an instant landmark, while on the inside they are planning a Zen retreat. But to succeed, their finances must be pushed to their limit, so Carl takes on as many of the specialist jobs as he can to save money. Kevin McCloud follows their progress.

Kevin McCloud meets a pair of civil partnered university professors who have decided to build their first home from scratch. In addition to all the complications this usually entails, they have also enlisted the services of industrial designers who have developed a new computer-assisted method for cutting precision-engineered building blocks from scratch. However, though the technique may be clever, its creators have never created a building before - meaning everyone involved with the project is taking a giant leap into the unknown.

The story of one man's heroic attempt to fulfill his childhood dream and bring back from the ruins an incredible castle set in one of the most beautiful landscapes in Ireland. Kevin McCloud meets more people trying to build dream homes, beginning with Sean Simons, who bought the ruins of Cloontykilla Castle in the Irish county of Roscommon with a view to using them to create a spectacular mock-16th-century home. However, the outlandish plans - including jacuzzis in the battlements and water-spouting gargoyles - have Kevin worried the project could become a garish nightmare, and his scepticism increases when he realises Sean has not consulted an architect. Disaster seems to be looming as the contractors get frustrated and planning regulations are ignored, but somehow things begin to slowly take shape - until a national economic crisis plunges everything into chaos.

Kevin McCloud revisits a couple who took on the task of constructing a sustainable house in the Kent countryside. Mimi da Costa managed the project despite a lack of experience, while her husband worked, and intended to have it completed in 16 weeks. But as the build threatened to drag on for months it became unclear whether their home would succeed in blending in and providing them with a greener lifestyle.

Kevin McCloud revisits Alan and Judith Dawson in west Cumbria, where they began constructing a prefabricated home in 2009.

Ever since he was a child, stonemason Adam Purchase has loved the old silver mine engine houses that characterise Cornwall's landscape. When he and his partner Nicola Brennan chanced upon a dilapidated Grade II listed engine house with planning permission to turn into a home, it was a dream come true. But converting this important historic ruin into a place to live was never going to be easy. The building itself was little more than a shell, with crumbling plant-infested walls and no roof, windows or floors: a challenge for even the most experienced builders like Adam. Meanwhile the banks refuse to lend them more than �100k, which Adam and Nicola both know is barely enough to get them through. Still, driven by their passion for old buildings, Nicola agrees to support Adam while he takes a year off work to complete the project.

Kevin McCloud meets estate manager Ed Waghorn and his wife Rowena, a couple living an almost self-sufficient life with their four children on a smallholding in Herefordshire.

Not everyone gets to live out their childhood dreams, but in 2004 Francis Shaw did exactly that when he bought a crumbling castle on English Heritage�s Buildings at Risk register, to restore. Little did he know what he was letting himself and his family in for by taking on this project. Set in the heart of the Yorkshire Dales, the peel tower dates back to the 15th century and was protected as a Scheduled Ancient Monument. It took months of red tape wrangling before Francis finally got permission to start working on the building, but with the rubble barely cleared, one of the enormous 700-year-old walls collapsed showing just how much of a labour of love this project was going to be. Two and a half years after Francis and his wife Karen moved in, Kevin McCloud returns to find out that the spiralling costs of restoring the castle has meant the fairytale life is nothing like Francis�s dream.

Mimi De Costa and her husband Andre, a doctor, had spent years looking for a plot of land when they came across a bungalow in Kent. The original bungalow They bought it for the site - 12 acres of organic pasture and woodland - and started to plan a new home for their sons, Sean and Tye, that would suit a lower impact way of living. But what they're building isn�t going to be a reproduction of the bungalow. It's a squarish, modular building, with glass walls from floor to ceiling. The outside of the building is clad in cedar that will go grey to match the surrounding oak trees. The idea is that by prefabricating most of the house it should be quicker and easier to put together on site. But although it will be precision made, it isn�t a kit house.

Dairy farmer Andrew Ainslie and his artist wife Meryl, who run a gallery on their farm, build a modern barn-style farmhouse on their 700 acre farm in the rolling chalk hills of Wiltshire.

Now, the couple face their biggest battle of all: rebuilding this massive ruin into a comfortable and luxurious five-bedroom home.

Kelly and Masoko Neville set about building not just a spectacular oak frame and straw bale house, but a whole new way of life in the Cambridgeshire Fens.

Kevin revisits Tony and Jo, musicians with Scottish Opera, who had long dreamed of a home in the countryside. They found a perfect site on the Clyde estuary in Argyll and Bute. Located in a small village on a hillside, it had glorious views as far as the isle of Arran and was less than an hour's drive from Glasgow. Inspired by local oak-framed barns, they gave architect Andy McAvoy an open brief. In return, he gave them a design that fused medieval and modern and promised a beautifully simple interior. However, the construction was anything but simple...

Engineering whiz Monty Ravenscroft built an extraordinary experimental home in Peckham. Kevin returns to see how it suits Monty and his partner now they have a child.

When Pilots Andrew Berry and his wife Helen bought their cottage near Guildford in Surrey 7 years ago they always planned to add a small extension.

Now it�s being completely demolished to make way for a new five bedroom Art Deco style house.

Dean Marks has dreamt of living in a church for as long as he can remember. After searching for the right building for years, he came across St Martin�s near Birmingham, a huge 18th century grade II listed church which looks more like a mausoleum. The church wanted �25,000 for it but Dean knocked them down to �12,500. Now, after fighting for planning permission for four years, Dean and his wife, Hilary, are about to transform this derelict monstrosity into a family home.

Kevin revisits Andrew and Lowri Davies who embarked on a project to build an environmentally friendly farmhouse in rural Wales.

As the budget spirals out of control, they find it increasingly difficult to balance the budget with their desire for a sustainable home.

James and Katrin Gray live in Bournemouth on the south coast. James runs his own book distribution business and Katrin works for an investment bank. They used to live in an apartment on the second floor of a former Victorian hotel. But three years ago, James bought the top floor flat. It was originally built as a solarium for the hotel in the 1920�s where holiday-makers could soak up the sun. Now James and Katrin plan to convert it into a modern, luxury penthouse

Chris Miller and his wife Sze Liu Lai lived in a tiny flat in East London with their two children Alexion and Tayszea.

Eight years ago Alex and Cheryl Reay left London for a new life in the New Forest. They bought a run down medieval thatched cottage and lovingly brought it back to life. Then just before Christmas, with Cheryl pregnant, disaster struck. A fault in the chimney caused a massive fire which destroyed the entire building. Overnight Alex and Cheryl had lost almost �400,000. Whilst most people would have walked away from this, Alex and Cheryl couldn�t let go of their dream. Nine months after the fire, they decided to start all over again and rebuild the cottage, bigger and better than before.

Every Englishman�s home is his castle but for Francis Shaw this is quite literally true. He and his wife, Karen, and their two young daughters, bought the ruins of a 14th Century castle in Yorkshire and took on the remarkable challenge of turning a pile of stones into a beautiful home. Surrounded by rolling green fields, the location is idyllic; however, the castle itself was little more than four crumbling walls.

Christine Benjamin and her husband Peter currently live in an Edwardian manor house called Medland Manor. Both in their 60s, the manor is getting to be too large for them, so they�ve decided to build themselves something smaller. Despite the manor�s traditional style, Peter and Christine felt strongly that their new building should embrace modern design whilst remaining sensitive to its site. So they came up with a house that is part traditional timber frame cottage, part modern glass pavilion.

Kevin McCloud revisits Nicky and James Dobree. Nicky was raised in France, James in Beirut � both have fond memories of the mountains as children. So it was natural for them to one day look to buy a place amongst France's tallest peaks, the Alps. The journey moving the family, including their two young sons, Fabian and Felix, from South London to a renovated 300-year-old farmhouse in Les Gets was to have its ups and downs. It was never meant to be a permanent move. The original plan was to develop the top two floors of the chalet so the family could spend the summer there, overseeing the completion of the bottom floors. They would then be able to rent our the whole chalet in the winter months. The family were only planning to use their new home for the summer seasons.

Kevin McCloud revisits Denise (Deni) Daniel and Doug Ibbs. The couple, in their mid-50s and from Dorset, bought a 19th-century manor house in Creuse, Limousin � in central France � on a Sunday, having seen it for the first time ever on the previous Tuesday on the Internet and visited it on the Thursday. They don't mind hard work too, which is even better news because the house was a wreck.

For six years Bruno and Denise Del Tufo stared at the large concrete water tower at the bottom of their garden trying to figure out what to do with it. It�s a very rare object � a square water tower on stilts designed by architect Edwin Lutyens, who built it to supply the manor house nearby. The planners were open to persuasion so they approached an architect who came up with a bold, uncompromising extension in metal, glass and concrete. Denise and Bruno were keen to keep the original structure visible so the new house is threaded between the legs of the water tower.

Theo and Elaine Leijser hoped to bring a bit of Dutch style to Scotland in the building of their first family home � a colourful, contemporary three storey house, with a striking cedar clad exterior. The couple stumbled across the perfect plot overlooking the beautiful Campsie Fells near Glasgow, bought it and began to plan their dream build.

Hillcott Barn looked more like a Tuscan monastery than an English barn. When the farmer put it up for sale, most people who viewed it walked away. It was dark and isolated and could only be reached by a half mile farm track with a steep 1:8 gradient. But furniture designer Robert Ellis (58) had had his eye on it for some time. For years he�d been jogging past the barn and always thought one day he�d like to live there. Against all advice, Rob and his wife Jane, (58) a textile designer, went ahead and bought the barn for �210,000 and proposed to convert at �250,000.

Jim Fairfull considers himself a very lucky guy. He was out fishing with a friend when he came across a beautiful, secluded loch. It�s a magical place with stunning views over the nearby hills. He got chatting to the farmer who owned it and discovered the site was for sale. Within a week, he�d done a deal and bought the land. The loch also gave them a fantastic opportunity to build a very unique house. They can control the water level of the loch which means they could actually build over the loch without worrying about flooding. So with the help of their architect, they designed an extravagant split level five bedroom house that actually hovers over the loch.

Anjana and David Devoy started building a contemporary home that curved around a protected chestnut tree in their garden. Kevin McCloud returns to see if their plan worked.

Andrew and Lowri Davies embark on a project to build an environmentally friendly farmhouse in rural Wales.

This is Belfast, one of the great cities of the industrial revolution, and home to Thomas and Dervla O�Hare. They�ve lived here for 18 years, and although they still love their tiny cottage for its compactness, they�re about to build something much, much bigger. They�re building a 21st century answer to the Roman villa, with a copper roof, glass and concrete walls and vast amounts of living space all arranged around a central courtyard.

Shaped like a curvy seashell, the new house has concrete and polystyrene walls, which spiral down from the central staircase. Her architect has promised it will take only six months to build but constructing a round house is never straightforward!

Kevin McCloud takes a trip back to the home of John and Eleni Flood who completely gutted their Victorian terraced house to create an open, light and modern space.

John Cadney and Marnie Moon have never had a permanent home. For 16 years they've camped on land owned by Marnie's parents because they could never afford to buy a house in the area where they live. So John, a carpenter, rolled his sleeves up and decided to build a house for his family with his bare hands. After much searching for the right kind of house they settled on an environmentally friendly four-bedroom log cabin. The whole thing was imported from Finland as hundreds of pre-cut bits of wood. All John had to do is figure out how it all fits together!

When lawyers Jeremy and Louise Brown walked into Upthorpe Farm in Gloucester, they couldn't believe their eyes. It was like stepping back in time. Apart from a few minor alterations, the Grade II listed 16th-century farmhouse had barely been touched for over 400 years and was completely unmodernised. There were original beams and doorways, original paint and plaster and a hay loft. Now that they've purchased the property their ambitious design plan is to bring the farmhouse into the 21st century, blending the original historic features with modern simplicity and luxury. Kevin watches on intrigued as they tackle the challenge of reconciling the very old and the very contemporary.

When Monty Ravenscroft and Clare Loewe began looking for a house to buy in London they soon realised that the only affordable option was to build one themselves. They snapped up a dirt cheap slither of land in Peckham at an auction only to be told it was too small to put a house on. Undeterred, three years ago, engineering whiz Monty began building an extraordinary experimental bungalow that filled the site to bursting point.

Kevin returns to see whether the couple's solo attempts to transform a wreck of an old stone building in Leith, with no previous building experience, has been successful.

Amid 55 acres of organic farmland in the New Forest, Lizzie and Mike set out to build an idiosyncratic home. They wanted a house that would reflect their love of travel and eastern cultures, yet blend into the very English countryside around them. Their first proposal, for a wooden Japanese house, was refused planning permission, but after three years of adapting their ideas with architect David Underhill, they were finally ready to build. Their ingenious design was in three sections: a living wing, a bedroom wing and a romantic tower.

Tony and Jo, musicians with Scottish Opera, had long dreamed of a home in the countryside. They found a perfect site on the Clyde estuary in Argyll and Bute. Located in a small village on a hillside, it had glorious views as far as the isle of Arran and was less than an hour's drive from Glasgow. Inspired by local oak-framed barns, they gave architect Andy McAvoy an open brief. In return, he gave them a design that fused medieval and modern and promised a beautifully simple interior. However, the construction was anything but simple...

Tom and Darron wanted to build a house that would be home to them, their art collection and their two large dogs. Darron's passion for surfing meant it would also have to be near a beach. They already shared a timber beach house in a hamlet on the Sussex coast, and when a neighbour's bungalow came up for sale, they decided to buy it, demolish it and build a dazzling white modernist house in its place.

David and Anjana's tiny coach house was proving too small for them and their two children. So they decided to build a new house in their own garden, which was big by London standards. But this particular grassy plot came with problems. It was overlooked by huge blocks of flats, and in the middle of it stood a chestnut tree they weren't allowed to cut down. They came up with an inspired solution: they would build a curving house along the borders of their plot. What's more, they would do a lot of the work themselves.

When Reuben and April came across a ruined 19th-century house amid the tower blocks of Leith, Edinburgh, they saw it as their future home. They had no clear idea of how to restore it, and precious little building experience. Still, they were young and fit (they had met on Reuben's climbing wall) and they liked a challenge. So they bought the crumbling shell and set about transforming it with their own hands.

Tom and Judy wanted more than just a home for themselves and their two children. On a site of outstanding natural beauty in Buckinghamshire, they set out to build an ambitious house - a symphony of angles, glass walls and exposed steel, with a dramatic inverted roof. Tom made himself site manager and main contractor. He had no experience but he liked a challenge - and, after all, how difficult could it be?

David and Greta loved their home, a modernist structure in Surrey that they had built themselves almost 40 years ago. It was filled with things they'd chosen over the years � design classics, mementoes, David's paintings. But that house was falling apart and had to come down. Meanwhile, they had lost their hearts to a German post-and-beam house, designed by architect Peter Huf and available as a customised kit.

Louise and Milko wanted to build the home of a lifetime. Milko's job as a well-paid City banker meant they could think big, so Louise set up her own architectural practice and they bought a disused violin factory in the heart of London's Waterloo. The crumbling building was hemmed in on all sides and had no views, but Louise had a vision of a spectacular loft-style home that would combine stunning design with utter luxury

Kevin McCloud revisits retired couple Denys and Marjorie Randolph, who decided to embark on their final building project, a brand new green oak barn-style house.

Kevin McCloud revisits the improbable build of two architects who built their central London house out of straw bales, springs, nappy cladding and silver tin.

Kevin McCloud returns to the Lambourn Valley to meet a couple who took three years to finish building their home on the Berkshire Downs.

Merry's family have been Herefordshire builders for generations, so she knew that the county was rich in traditional building crafts. She and Ben decided to combine these with technology for a new house with a genuinely rural feel. Her father drew up a design that followed the traditional cottage layout while incorporating modern comforts.

The old quarry stood on a slope of the Eden valley and commanded beautiful views. Local architect John Bodger designed a two-storey house that burrowed backwards into the rock and made maximum use of natural resources for light, warmth and power

After 10 years of living in a small house in east London, John and Eleni hankered after modern, open-plan living. They didn't want to move, so they decided to give their Victorian terrace home a radical redesign. The house was in a conservation area, so the outside had to remain unchanged. Inside, however, they decided to rip out everything including walls, ceilings, floors and start again.

For Philip and Angela, the build was part of a life change that had begun two years earlier. Just after their second daughter was born, Philip fell seriously ill, prompting the family to leave London and move back to his parents' village. Acquiring the site was easy, as Philip's parents owned it. Getting planning permission took longer, and a crucial factor in their success was that they would be restoring the outside of the barn and keeping the innovation hidden

For 10 years, Ben lived in tents and caravans in a wood in West Sussex. As a woodsman, he needed and wanted to live among the trees. But after a battle with planning he finally got permission to build himself a house with more creature comforts. He invited volunteers to help him build one by hand, from the materials growing around him.

The 1930s derelict water-works Chris and Leanne fell in love with was huge and its design had clearly been inspired by Gilbert Scott's Bankside power station, now better known as the Tate Modern. But nothing would deter the couple. 'We looked at it,' said Chris, 'and saw our home.'

'Is it a bold contemporary design or a garden shed?' John and Terri found themselves asking, halfway into their build. They had knocked down a derelict house in a beautiful rural setting and commissioned commercial architects to build them a new one. But was it too small for them, their young son and the baby on the way?

Sue and Martin took a holistic approach when they converted a pair of Devon barns into a family home. They believed that the house should look like a natural part of the landscape. So they built it using environmentally sustainable techniques and allowed much of its design to evolve during the build. The oldest barn, dating from the 1600s, was built from stone and cob - a straw-and-mud mixture characteristic of Devon - while the newer, 19th-century barn was totally of stone. The older barn would have a thatched roof, the newer barn slates. A south-facing sitting room would overlook a double-height glass atrium, which would become an indoor garden, filled with citrus trees. Four bedrooms and a study would go upstairs.

Kevin is in Amersham to update on a project taken on by Deborah and architect Andrew. Their venture involved designing an 'invisible' house that blended in with the surrounding reservoirs.

Kevin McCloud re-visits Adrian and Corrina, who decided their first home was to be a 300-year-old ruin. The former cottage is set in the inhospitable climate of the Brecon Beacons National Park.

Sarah, a maker of modern jewellery, and Coneyl, a freelance photographer, wanted a modern home from which they could both work. But they also wanted a uniquely personal house. So they commissioned architect Mike Tonkin to come up with a radical design for their long, thin site in a north London residential street.

In May 1999, 11 people in Bordesley, West Birmingham, set out to build their own homes. Few of them had any professional experience in construction. For the previous two years, the Accord Housing Association had been training them in the skills they would need. Now they were to put them to the test. Angela, who worked for Accord, would be the project co-ordinator. Peter, a builder with 20 years' experience, would be site manager, overseeing the work. The group members; Calvin (who was appointed leader), Paul, Carol, Mr Azad, Petrona, Tab, Gerald, Paul, Yasser, Richard, Bash - had not known each other when they signed up, having been attracted to the project through advertising and word of mouth

When Rupert and Julie bought a hilltop site in the Berkshire Downs, they were determined to build a house that would make the most of the countryside and stunning views. They turned to architecture firm Roderick James, which specialises in modern design and traditional timber craftsmanship. Together with architect Hugh McGann, they came up with a house of green oak and glass, built in an unusual cruciform (cross) shape.

An isolated hilltop in the Brecon Beacons might seem an inhospitable place for a couple's first home. But Adrian and Corinna both grew up in the area, and the ruined farmhouse they chose to restore had been in Adrian's family for generations. The site's lack of mains water and electricity gave them no qualms. True, the track up the hill was often inaccessible in winter. But the landscape was beautiful and they both felt they belonged there

A derelict woollen mill in a Yorkshire village may not say 'modernist' to everyone. But Chris and Gill - who, fortunately, run their own specialist joinery business - saw it as the perfect opportunity to create a visionary home. They liked the traditional brick of the building and opted to keep the exterior virtually untouched. Inside, they would strip everything out and make a home of fluid spaces, based around an open-plan ground floor, an atrium and a galleried upper floor.

With a plot of land in Sussex overlooking the South Downs, newly-weds Jane and Willem wanted a house that would be atmospheric and open to the countryside. Inspired by memories of America, Jane planned a New England-style gabled house with large windows to make the most of the views.

Helen and Mark had always dreamed of owning a Georgian house but knew they couldn't afford the genuine article. So they decided to build their own. They bought a large plot of land in Surrey, surrounded by trees, and commissioned an architect who specialised in conservation architecture to design it.

This project was a co-operative venture - 10 young families each put in 30 hours of construction work per week. Kevin travels to Brighton to meet a co-operative of ten young families, including ex-travellers and single parents, who are building both their own and each others homes. A housing association bought the land from the council for �58,000. Paul then worked with the association to put the co-operative together. All the members were people on the council's housing list.
