Kevin McCloud revisits Vicky and Ed, who in 2015 broke free from the shackles of their hectic London lives to try to build a new life in the Somerset countryside. With a budget of just over £200,000, they set out to transform an old derelict cowshed into a 21st-century off-grid smallholding. With no building experience or project manager, they took on this dramatic transformation themselves, learning building techniques from the internet.

Kevin McCloud visits Sue and Martin who set out to renovate two 16th and 18th-century barns in 1999. Without conventional plans, surveys and specifications the project was delayed a number of times. The original deadline of Christmas 2000 came and went and by September 2002 the build was still not finished. Kevin returns two decades later to see if the house is finally complete.
