One of Indonesia’s tallest buildings, defining Jakarta’s skyline
Project Overview
Gama Tower gives Jakarta a defining new landmark on its skyline. At over 285.5 metres and 64 storeys, it stands as the tallest building in Indonesia, and was ranked the 14th tallest in the world when completed in 2016.
Bringing together commercial office space, The Westin Jakarta and a podium ballroom for events and functions, the tower gives the city a place to work, stay and gather, with expansive views across Jakarta for all who visit.

- Design of the external stormwater system, including soak wells and ponds in accordance with authority requirements
