E5 - Herefordshire: The Recycled Timber-framed House

Aired: October 12, 2011

E6 - Cornwall: The Dilapidated Engine House

Aired: October 19, 2011

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.
