Part of a series I made about Britain’s Oldest Family businesses, this film is about R Durtnell and Sons, a family building company in rural Kent that is almost 400 years old. In this clip, Alex Durtnell, who has recently taken over as head of the family business, explores a house built by one of his Elizabethan ancestors. It’s surprising how much things have changed, and how little.
