The current development projects include construction of a brand new international terminal, known as T2 in order to differentiate it from the Meenambakkam cargo Terminal 2, in place of the older Terminal 3 which currently lies in between the two newer Terminals 1 and 4. The design is a collaborative effort of team lead involving Frederic Schwartz Architects, Gensler, and led by New Delhi-based Creative Group. Creative Group is the principal architect for the project providing comprehensive architecture and engineering consultancy for the design of the passengers terminal buildings, parking garage structures and roadway access system. The proposed design, based on Gensler's Terminal 2015 concept, will be connected with the design elements of the existing Terminals 1 and 4. It was earlier reported that the new terminal building will have a handling capacity of 10 million passengers and when integrated with existing terminals will provide for a handling capacity of 23 million passengers a year. The new terminal building is expected to have an area of about 1,40,000 m² with 104 check-in counters, 16 aero-bridge and 60 immigration counters and the two runways would be interconnected by a network of taxiways. The 24,760-million expansion programme commenced on 11 July 2018 and will be completed by 2021. Once completed, the T2 will serve as the airport's sole international terminal, making the newer Terminals 1 and 4 the domestic terminals.
