Harrods owner Mohamed al-Fayed has plans to build a zoo on the roof of the London store. The Observer

The concept is the brainchild of Harrods’ creative director, Bill Mitchell, who is retained by al-Fayed to come up with innovative ideas at 158-year-old department store.

A Harrods spokesman confirmed a zoo could form part of a new attraction, either as an extension of its pet department or by making use of the labyrinthine store's roof space.

'It is not a case of elephants on the roof,' said a spokesman. 'We would have to think about the planning implications as well as access, and would obviously want the animals to be as comfortable as possible. It is one of Bill's many ideas.'
