Situated on one of the most important junctions of Istanbul, Ayyıldız Building has become an iconic symbol with its triangular parcel structure. The residential structure planned on this parcel has reinforced such recognition by repeating the triangular form of the ground floor on the vertical lines. The east facade of the parcel has been designed with a giant LED screen. In this way, the dynamism brought by the intense traffic has been carried over to the facade as well. Thanks to the double-walled facade, natural ventilation has become possible. The ground floor has been preserved as commercial area whereas the upper floors have been planned as residential. In consideration with the dominant view, the penthouse has been projected as restaurant. The roof cover of the restaurant area has been designed as convertible. In this way the area may serve as an outdoor restaurant when the climatic conditions are favorable.
