The latest addition to TaiKoo Place is One Island East, located at the Aik San Building site on Westlands Road. It is the tallest office tower in TaiKoo Place. Attaining a height of 300 metres, it is the iconic landmark of the district. Its 70 floors incorporate 59 office floors. With a typical floor plate of 2,300 square metres, it provides a total office area of 140,000 square metres.

Shunning the conventional podium structure, the tower sits in front of a large landscaped open space to the east, which is designed as a series of platforms at different levels, interlinked by water features.
