Under the Colombo Master Plan of 1979 all government offices in Colombo are to be moved to the administrative capital of Sri Jayewardenepura, Kotte, enabling the release of high-value land in Colombo for commercial development. The headquarters of various defence institutions were separate and scattered across Colombo, resulting in great inefficiency and high-security zones amidst commercial areas, causing disturbance to the general public.^[2]

Thus Defence Headquarters Complex allows resources to be better utilised and provides defence personnel with a state of the art office complex. This increases operational, administrative and logistic efficiency and minimises the disturbances caused to civilians and economic activities.^[2][3] Construction commenced in 2011 with the parliamentary approval of Rs. 20 billion allocation. In 2015, with the change of government, construction halted and allocated funds were taken over by the Treasury which caused construction delays.^{[4] [5]}

In November 2019, the Sri Lanka Army began moving its headquarters to the completed blocks 6 and 7.

In May 2021, Ministry of Defence shifted to the newly constructed Block 1 of Defence Headquarters Complex.^[6]
