One Causeway Bay

Rising to the status of its legendary address, One Causeway Bay blends Hong Kong’s past and future, offering office and retail programming in a testament to the city’s growth.

As the first plot of land sold after the territory became a British Colony in 1841, the site of One Causeway Bay is locally known as Hong Kong Land No. 1 and is well integrated into the fabric of the district and the Victoria Harbour waterfront. Across 24 floors, One Causeway Bay features office space as well as retail, entertainment, and dining programming within the four-level podium and top levels of the tower.

The tower’s trapezoidal floorplate maximizes the site’s footprint as it expands towards the street and commands views of the water. This influence continues in the façade design, as the glass imitates both the stillness and movement of Victoria Harbour. The front of the building is comprised of vertical glass panels that alternate between outward and inward positioning. At the podium, the waves are represented horizontally. Stone-clad columns lift the building to create a covered arrival experience with a setback glass entry.

The upper floors of One Causeway Bay offer a restaurant and landscaped roof garden all with panoramic views of the cityscape and waterfront. An LED screen, visible from across the harbour, defines the building’s crown and serves as a prominent landmark. Key sustainability features include a triple low-e insulated glass facade for high thermal performance, landscaping to minimize the heat island effect, and photovoltaic panels to generate renewable energy on site.
