Construction of Thamrin Nine Tower 1, which is named as Autograph Tower, topped off in October 2020, making Autograph Tower the first supertall building in Indonesia. It is one of the twin paired towers, the lower four floors of which will be linked by retail podium. The architectural height of the tower 1 is 385 meters. The tower has 75 floors above and 6 floors below the ground. There is a three-storey observation deck at floor 56–58 and a Sky Garden area at the tower. The tower is designed by Kohn Pedersen Fox Associates. The lower floors of the tower are for office, whereas the upper floors will be occupied by Waldorf Astoria Hotel. It is a class A, green skyscraper with platinum certification and uses up to 30% less energy compared to a conventionally-constructed tower of the same scale. The Autograph Tower is the tallest building in the Southern Hemisphere, surpassing the Q1 Tower in Australia, at 322.5 m. (Source: Wikipedia.org, CC BY-SA)
