The colors of Istanbul are reflected on the world’s largest vaulted roof ― 

Istanbul has emerged as one of the world’s busiest air traffic hubs, because of its geographic location. Recently, the city launched its third international airport, the biggest in the world: the terminal is covered under an impressive translucent roof, designed by Grimshaw Architects in a way that recalls the city’s fascinating history: consecutive vaults in slender aluminum profiles bring copious amounts of natural light into the interior, recalling Turkish bathouses or the spectacular Grand Bazaar at the historical core. With its sleek design, the airport bridges Istanbul’s past with its future, in the same way that this exceptional city spans over two continents.

The colors of the roof, in smooth whites, multiply natural light and send it deep into the interior; at the same time, they take on the hues of the bright billboards wrapped around the countless retail and recreation areas on the ground floor. Despite its imposing geometry and large sizes, the space never appears to be static: the wide, undulating surfaces of the terminal reflect the colorful crowd from every corner of the earth moving through the airport, twenty-four hours a day.

Interpon D2525 superdurable powder coatings were specified for the project, because they were the only colors capable of matching the very high standards of resilience required in the project; they were chosen for their very high quality, for constituting the longest and widest portfolio of works in the world, and for their exceptional sustainability. AkzoNobel developed custom Superdurable White Matt, Silver and Dark Metallic Smooth Matt effect colors, applied on interior and exterior aluminum profiles, as well as on all bespoke aluminum parts of the central terminal vaulted roof.

The project received the World Architecture Festival Award in Berlin, in the Inffrastructure – Future Projects category. The iconic elliptical control tower, designed by AECOM and Pinifarina to resemble a tulip, recalls the sigil flower of Istanbul for many centuries.

Initially, the airport will serve 90 million passengers a year, that will increase to 200 million by 2028, when the project will be complete. It will feature six runways, eight control towers, 165 boarding bridges, 500 aircraft service capacity and terminals connected with rail spanning 76 square kilometers.
