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!

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.

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.
