Neighboring second international airport of Istanbul, Esas Aeropark consists of 2 separate blocks with 7 and 9 floors, respective to topography. Soft curves of buildings, setting of spaces and their connection arcs create an elegant flow; the major reason of the form comes from the idea of breaking the strong north-east wind. Curvilinear parallel facades of the two buildings produce a semi-sheltered, 20 meters wide pedestrian link that forms an integral part of the network of neighborhood connections. Uppermost floors of the rear building designed as residential units to be rented by airline professionals and long-term visitors. The “simulation zone” located below ground at the upper elevation with transparent glass openings on top, welcome curious passersby to take a look at. Conceptually the building is a permeable and transparent workspace with the choice of visibility and interaction with the existing surroundings.
