For 10 years, woodsman Ben Law fought for planning permission to build himself a house in the heart of the woods where he worked. But there was a condition attached: he could never sell the house; only pass it on to his successor. Ben wanted his home to be totally self-sufficient with no mains services, and decided to build it using only materials from the woods, using techniques pretty similar to those used a thousand years ago. Kevin catches up with Ben to see how he and his house are doing.
