World's Largest Casino follows the construction of the world's biggest casino and its second biggest building. It's being sited in Macau, in Southern China, which is being groomed to be Asia's capital of gambling. The Venetian is to be built by the Sands Corporation of Las Vegas, and is to feature a giant hotel with 3000 suites, a 15,000 seat arena, a theatre, event halls, 350 shops along indoor canals hundreds of metres long, an outdoor lagoon for gondola rides, and above all, a huge casino floor the size of eight football pitches. We follow the reclamation of land between two islands for this project, and watch it fly up in record time due to special working methods being devised – from on-site factories, to having prefabricated parts trucked in from China. We see how the ambitious designs are brought to reality, despite the pressures and an environment that's very different from America, both in terms of climate and culture. We go in-depth into the amazing concern for detail in the outfitting and decoration which will turn a giant concrete conglomeration of structures into a place designed to entice people to stay as long as possible. Andwe meet the people responsible for putting the project together, and see how they co-operate to get the resort open on time. But will the public come to visit this US$2.4bn megastructure? There's no guarantee...
