The Project is developed in 2 Phases. Phase 1 contains about 270,000 sq. ft. of office space, 340,000 sq. ft. of retail, dining and entertainment spaces, and about 900 parking spaces, while Phase 2 provides an addition of about 390,000 sq. ft. of office space, 600,000 sq. ft. of retail space, and an underground connection to the Central MTR Station. It will be a world-class iconic landmark of Hong Kong.
