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 David and Anjana Devoy's who'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.
