The Indian Parliament has a brand-new building designed to address the present and future needs of efficient parliamentary functioning. The new building measuring about 21,765 sq m was to be constructed on a triangular-shaped plot measuring approximately 10.5 acres. Hence, the design team from HCP Design, Planning & Management (HCPDPM) decided that a triangular building would make the best use of the available space as well as lend itself well to the three primary functional requirements—the Lok Sabha, the Rajya Sabha and the courtyard.

Prior to developing the initial design, the design team studied the architectural language of the existing Parliament House, a Grade I heritage building, the utilisation of space, the facilities and adjacencies, circulation routes, protocols and security arrangements, furniture requirements, the additions and alterations made to the building, and its expansion possibilities.
