Grand Designs - Bath House

Bath may be famous for its Georgian architecture, but Tiffany Wood and her husband Jonny have chosen it as the location to build themselves a striking Modernist home, just a mile from the city centre.

Rather than go down the traditional building route, they opt for a German pre-fabricated kit house with great green credentials. But before they can even think about building their house they have to prepare their site: a fiercely steep hillside.

Tiffany and Jonny embark on the biggest ground works project Grand Designs has ever seen, costing around £300,000.

And, just when they are about to complete these mammoth works, the weather turns bad and disaster strikes.

Their neighbour's wall collapses in a storm. The resulting damage could cost them nearly £100,000.

Determined to carry on, even through 80 tonnes of extra mud, Tiffany and Jonny persevere, and a year into their project, are finally able to go to Germany to choose their house.
