The metro station at Chennai airport is planned right in front of the terminal buildings with its axis lying on the axis of the whole complex with the New Domestic & International Terminals being layout at an equal distance from it, thus providing easy access to both of them. The new Airport Terminals of Chennai are going to be one of the first Airports in India which can boast of having the Inter-modality of various transportation systems viz. Air Travel, National Highway, Suburban Railways and Metro Rail with the Metro Rail being the latest addition to this unique Multi Modal Transportation Complex. The central location of the station makes it all the more important that it supplements the prominent Architectural vocabulary already prominent at the complex yet not compromising on the identity of its own. The building has to be subtle yet dynamic in form justifying its central location in the site yet not overpowering the Airport Terminals. The building thus designed with portal frames which are being inspired from the now famous V-columns of the Airport adheres to the vocabulary of the complete campus.The flow of the passengers from both the Terminals is showcased by building's form consisting of two identical tubes ascending towards the central axis from both the sides and penetrating inside the biggest central tube.
