Seemingly locked in a battle for superlative supremacy, China and Dubai continue to construct a dizzying number of record-breaking attractions. Home to Burj Khalifa, the world’s tallest building, Dubai has this year inaugurated the world’s biggest natural flower garden, the world’s tallest hotel and the world’s tallest twisted tower. China, meanwhile, is preparing to open a ‘groundscraper’ cave hotel that will burrow 19 storeys below the ground, and it has now opened the world’s largest freestanding building in Chengdu.

Named New Century Global Center, the colossal structure is 500 metres long, 400 metres wide and 100 metres high, and contains a total floor space of 1.7million square metres. Providing a sense of scale, the Sydney Morning Herald reports that the building is large enough to accommodate the Sydney Opera House 20 times over.

Visitors to the attraction may find it somewhat less highbrow than Australia’s famed cultural attraction, however. The building will house cinemas, shopping centres, office space, hotels, conference centres, a water theme park with artificial beach and various other attractions including a replica Mediterranean village.
