After 19 years at the top, Wisma 46 is no longer the tallest building in Jakarta. In 2015, the Cemindo Tower surpassed it, rising to a height of 289 metres and 63 storeys. But a new proposal designed by Woods Bagot for PT. Arthaloka Indonesia just steps away from Wisma 46 would handily take that title, and may even become the tallest building in the southern hemisphere. Dubbed Arthaloka Square, the plan calls for several glassy office buildings, one of which could reach 400 metres into the sky.
