Property boss Gerald Ronson doesn’t strike one as the feng shui type. But it appears he has become quite au fait with the concept. Last week, at a ceremony laying a time capsule in the foundations of Heron Tower — to be London’s tallest office building – Mr Ronson, wearing a hard hat and fluorescent jacket, explained how the capsule included an ethically-sourced tortoiseshell. He said: “In feng shui theory, the tortoise, dragon, phoenix and tiger form four kinds of energy that surround a building. The tortoise represents a strong back, protection and security.”

Aha, so feng shui is good for business. That’s more like it. Meanwhile, his Heron International company has agreed terms with luxury hotel chain Four Seasons to develop a hotel as part of its Heron Plaza in the City of London.
