George meets Yohance, who has bought an office unit on a commercial estate in London, which he plans to turn into a two-bedroom house. At £360,000 it was half the price of residential equivalents nearby, but it's a cavernous, sterile and dark space, so the odds are stacked against him and his conversion. Is it even possible to make it the stylish and comfortable first home he wants?

Rollo and Olivia have decided to swap city life for the rolling Chiltern Hills, snapping up an old barber's shop and its 17th-century attached building in Amersham. Run as a business for over 100 years, the Grade II listed hairdressers is in a state of serious disrepair. Their plan to convert the loft and create a modern open-plan ground floor is perfect for modern family living, but it's a risk in a building that's over 300 years old.
