The 'Kuala Lumpur Waterfront' may be unfamiliar to many. Kuala Lumpur is a city that originates at the confluence of two rivers, the Klang and Gombak Rivers. The waterfront used to be very busy with activities when it was once a trading post for the export of tin. This was once the lifeline of the city - its main mode of transportation. The activity at the waterfront has changed over the years along with the social, economic and physical development of the city. Many waterfront cities throughout the world have gone through similar changes when the mode of transportation changed from water to the motor system. A number of cities have made efforts to integrate the cities' activities with their water body. This research attempts to investigate the functional aspects at the Kuala Lumpur waterfront within the city centre in terms of its level of contextual integration with the urban rivers in the current context. The technique adopted for this research is field observations which include building use survey and time interval observation to investigate the Junctional aspects in ten demarcated zones along the Kuala Lumpur waterfront within the city centre. The research concluded with the finding that all the zones have medium level of contextual integration between the waterfront and the urban river in terms of its building use, which depends much on the continuity of activities, their positioning location, accessibility and the provision of space and facilities. © 2016 The Authors.
