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.
