Zaha Hadid Architects has posted a new construction update on its forthcoming XRL Topside Development at the Hong Kong High-Speed Rail West Kowloon Terminus. 

The project, which adds 3.2 million square feet of civic, office, and retail spaces above the existing train station, includes two pairs of towers connecting with a large landscaped central plaza area and a sculptural pavilion, each designed to resemble flower pedals and located at either end of the site. 

Construction has now progressed to the roof level of the new structures. The firm says they are targeting a LEED Platinum certification as well as other industry credentials for sustainability on the development, which also yields a total of 100,000 square feet of garden terraces. 

UBS is said to be among the first corporate tenants. Fans can anticipate an official 2026 public opening, the same year the first phases of ZHA's new Western Sydney Airport International Airport design will debut in Australia.
