Abstract
The seaplanes used for supporting the fleet for the military purposes during World War I, have been used as a new form of transportation technology in 1920s and 1930s as 'Golden Age' of aviation in Western countries (in Europe and United States) for the civil and commercial purposes; it has become considerably popular and in great demand. In those years, as an issue being approached in Istanbul simultaneously with Europe and United States, culture and voyage of seaplane had remained as an issue implied and not being significantly researched. Newly-emerging and young many European companies have anticipated route of Turkey as the shortest cut to travel to and connect with East, taken steps and built facilities accordingly and made relevant connections. In this paper, Italian AEI (Societa Anonima Aero Espresso Italiana), being established in 1920s in Büyükdere, European side of Istanbul for civil aviation services, is construed architecturally based upon Archives of the Prime Ministry of the Republic.
