The KK Leung Building forms part of the Redevelopment of the Main Estate of the University of Hong Kong. The building has a net floor area of about 15,000s.m. and contains a number of academic departments such as the Department of Law, the Social Sciences Departments and University Language Centre The Senior Staff Common Room occupies the two topmost floors.

To make the best use of a difficult site, the building is designed as a 20-storey tower block with a central core housing the lifts and staircases giving maximum perimeter area for lecturers’ offices on most departmental floors. Heavy student traffic generators such as centrally time-tabled lecture rooms are located near the entrance levels and the building is linked to the Knowles Building ground floor and the Library level by a footbridge. The pedestrian access route is planned as a lift tower serving between Bonham Road entrance and the footbridge.
