Apart from the other projects along the Büyükdere Avenue, which is the main business district of Istanbul, Maslak No.1 Office Tower was designed to enrich the quality of the typical office space by vertical gardens. In order to accomplish that, a rational office block which was planned over a rational 8.25 x 8.25 m grid, enveloped with a free formed glazing system. The envelope, acting as a secondary facade in south and west directions, is detached from the building up to 17 meters wide letting vertical gardens in 20 meters high. The space in-between two facades was considered as a buffer both for the acoustical and the climatic sense.
The curvilinear plan of the facade formed by the 150x200 cm rectangular modules was designed regarding the perception from the highway. The facade was considered as a silicon glazing system having a translucent film layer over it. The opacity of the film layer diverse, up to the orientation of the curvilinear facade; on southern façade a less transparent pattern was chosen; however in north, almost a transparent film was used.
