Hong Kong West Kowloon Station, one of the largest below-grade rail terminuses in the world, maximizes civic gestures both externally and internally. The design includes a vast 20-meter-deep sunken atrium hall space that offers views through the south façade of the station toward the central district of Hong Kong and beyond to Victoria Peak. This view is facilitated by the exterior ground surface that slopes down toward the hall – an area called ‘Civic Plaza’ – and an accessible green roof that gestures toward the harbor, the height reaches 25 meters above the ground.
