Seasons & episodes

Kevin returns to one of the most ambitious Grand Designs ever, a million-pound amphibious house on the Thames. Now it's finished, does it actually float?

Kevin McCloud catches up with one of his favourite ever Grand Designs: Rebecca and Gregory's radical, experimental timber refurb of an old bungalow.

Kevin McCloud follows plumber Jon Martin and ceramicist Noreen Jaafar as they transform a neglected half-acre site in Gloucestershire. However, they are unable to cut down the 27 protected trees on the plot, so their solution is to build a big, modern treehouse with stilts screwed into the earth and balconies that will have views for miles.

Kevin McCloud follows Matt and Sophie White from Sussex as they build a giant family house of fun for themselves and their children. Going against the norm of designing a serious and practical home, the couple's property features a revolving bookcase door, secret dens, hiding places, one-way mirrors, and a fireman's pole. Matt uses a steel frame system to allow them to change the layout of the property, and other changes include amending the window shapes and sizes, and adding a half floor to create a James Bond room.

Kevin McCloud meets Tom and Danielle Raffield, whose lifelong passion has been steam-bending wood. They've used the technique to create extraordinary furniture and lighting, but now plan to use it on a larger scale. In an attempt to escape the confines of their tiny gamekeeper's lodge, they have decided to build a wavy wooden house in South Cornwall, completed with curved cladding, twisted furniture and interior walls covered with weathered timber. With a £100,000 budget, the pair have decided to do a lot of the building themselves, and Kevin is on hand to discover whether they're up to the challenge.

Kevin McCloud meets Michelle Parsons, an artist and teacher who decided to seize the day and build her own private hideaway in a woodland environment in Essex after she recovered from a serious illness. Together with her architect husband David, Michelle planned to construct a sleek, black-clad, three bedroom house complete with an art studio. However, torrential rain and a potentially disastrous gas leak stalled progress on the build, and as construction gets under way, Kevin wonders whether the couple's decision to eliminate windows on two sides of the property may leave them living in a gloomy bunker.

Bolton-based bricklayer Paul Rimmer, who has spent his career restoring and renovating Victorian terrace houses, sets his sights on constructing a state-of-the-art home on a budget of £350,000. However, instead of using the construction materials he has spent the past 40 years mastering, he has opted to build his new home from wood. Roping in his wife Carol, daughter Abby and a selection of favoured workmates, Paul and his team begin work on the ultra-modern, five-bedroom build, and Kevin McCloud reveals how extreme weather, exhaustion, and rapidly dwindling funds place the entire project in jeopardy.

However, the pair soon find themselves struggling to balance their busy working lives alongside project managing the build.

Kevin McCloud meets young architect and shed fanatic Micah Jones, who plans to transform an old agricultural building in County Down, Northern Ireland. Micah plans an upside down, four bedroom shed using new techniques and materials, but the £200,000 budget runs short, and Micah is forced to take on some of the building work himself.

Kevin McCloud meets Chris and Kayo, who plan to build a unique, Roman-inspired home on the protected land surrounding one of Britain's most historic abbeys in Hertfordshire. The pair find themselves constrained by stringent planning conditions, and the intricate and complicated build puts both their schedule and budget under a great deal of pressure.

Beth and Andrew rescue a crumbling Victorian dairy, hoping to make it into a 'shabby chic' family home fit for modern life. But is the building simply too derelict?

The building was inspired by an ammonite shell and has a scaly, curving structure that spirals over two levels and combines natural materials with the latest modern technology. However, completing the project within the 12-month schedule may not be possible.

After 15 years of saving and planning, ecologist Fred and communications manager Saffron Baker start building work on their new family home in a village in the Peak District.

Design engineer Joe Stuart and service designer Lina Nilsson take on the London property market, as they build their own home on a miniscule 38 square metre plot. Joe designs a split level, six half-floor house that will cleverly maximise the space, but the project is soon runs months behind schedule, and thousands of pounds over their budget.

Progress on the build was slow as Ed decided to do most of the work himself, and after four years the house was still a shell. Now, years later, is it possible this house may finally become a medieval masterpiece?
