Charlie meets Adam and Vicki Nicholl, who plan to self-build a new, barn-style home in the garden of Adam's mum's home. Vicki is a tax advisor and Adam works in marketing. The 30-somethings have grown tired of life in the city and are planning to move back to the village of Pirton, where they grew up. Doing the building themselves is the only way they can afford to get the house they want in the village, and they could potentially save around £100,000 by doing it this way. After having a close look at their plans, Charlie's got some bright ideas, but can he convince Adam and Vicki to alter the designs of their dream home?
