Unlike the other three towers, which were completed back in 2011, the new tower will stand alone, but will take cues from the existing glass buildings.

The fourth tower will have around 1,000 suites, a sky roof and swimming pool, meeting rooms, ballrooms and a 15,000 seat music arena.

Plans are in place for the work to start imminently, but there is no expected completion date as of yet.

The Marina Bay Sands is a giant luxury resort, which has three 57-storey towers, connected by a sky garden. Within the resort, there is a museum, two theatres, a casino, shops and restaurants.

Sheldon Adelson, Chairman of the casino's owner, Las Vegas Sands, said: “Marina Bay Sands is an iconic tourism destination that has exceeded all of our hopes in growing leisure and business tourism in Singapore.”
