The practice were the lead designer for the terminal building at Istanbul Airport. Based on the Black Sea coast 35km outside the city, it is the largest single terminal in the world with an initial capacity of 90 million passengers per year. Phase 1 saw the construction of the terminal together with three runways and substantial aviation related development. Further phases inlcuded additional runways, terminals and satellite piers increasing the airport capacity to 180 million passengers. As the lead designer we revisited the concept design originally prepared by Grimshaw, Nordic and Haptic, refining and developing it to suit the evolving requirements of the client including architectural planning, aesthetics, operational issues and buildability. Delivery architects on the scheme are Fonksiyon (central processor and the external envelope) and TAM/Kiklop (piers).
