Xujiahui will have a new downtown landmark when the tallest building west of the Huangpu River is completed around 2023. 

Construction has started on the basement of the building after 4,700 cubic meters of concrete were poured into the basement for the Xujiahui Center over the Spring Festival holiday that ended on Wednesday, marking a milestone for the project, the Xuhui District government said over the weekend.

Dubbed the last core site for development in Shanghai, the complex covers a total floor area of 782,000 square meters, twice as large as the Shanghai World Financial Center in the Pudong New Area. It will comprise three skyscrapers, including a 370-meter tower on Hongqiao Road and Yishan Road N., west of the landmark Grand Gateway Plaza.
