Harrods has launched its new Toy Kingdom featuring an intergalactic science lab and an enchanted forest complete with birdsong following a multimillion-pound overhaul.

The department took more than two years to complete and is 190 square metres larger than its previous location

The luxury department store said the 2,400-square-metre “destination” was one of its most extensive refurbishment projects and promised six individual “multi-sensory worlds”.

The store focused on themes rather than gender, with separate areas including The Big Top based around a circus, The Odyssey room dedicated to science, gadgets and space, and the Reading Room, where children can climb into cubby holes to listen to stories.

The Wonderland showcases Harrods’ most exclusive toys, including a £9,000 giant doll’s house and a £6,995 black Mercedes SLK that runs on petrol.

The department took more than two years to complete and is 190 square metres larger than its previous location.

David Miller, director of Harrods Home, said: “Harrods is London’s third most visited destination for tourists and we wanted to create a landmark family shopping experience that really was unforgettable for our visitors.

“It was important for us not to just build a conventional retail department but to create multi-sensory environments that surprise, entertain and encourage shoppers to interact and play.”
