Times Square is a shopping centre and office tower complex in Causeway Bay, Hong Kong. The complex, owned by Wharf Properties, part of The Wharf (Holdings) Limited group, opened in April 1994. Times Square is considered the first of its kind, the first “vertical mall” in Hong Kong. Due to the high land price in Hong Kong, and the higher yield on retail property, Times Square departs from the common western model of the flat shopping mall. The space allocated to retail is configured over 9 stories. The mall and lifts to the office tower are accessible by long escalators linking the ground floor podium and the first level of the mall. Caltite system has been used for the 6-level basement for reliable protection against the challenging condition of high water table.
