A piece of the new headquarters building fell on a Willis employee.

Willis’s soon-to-be-finished, Norman Foster-designed, £110m HQ claimed its first casualty this week after a piece of the building fell on an employee.

A spokesperson said: “It was a minor incident and no one was seriously hurt.”

The design for the building, which rises 125 metres, was originally based on the shell of a prawn, but a top dog from Willis later straightened the curves on the architect’s sketches.

So how could the accident have happened? Backchat reckons it was a failed attempt to pin a giant Willis badge on the lapel of the prawnscraper.
