One & Ortakoy is a mixed use complex in the Istanbul neighborhood of Ortakoy. The project consists of two buildings; one building is residential and the second is commercial. Nestled next to a hillside, the project will be an iconic step forward in the modernization of the area.The project’s form, facade and overall organization developed through a series of experimental strategies influenced by contextual elements. GAD’s design solution optimizes the use of the various programs distributed throughout the site. The roofs on both buildings are intended to be landscaped recreational playgrounds. These green roofs lessen the scale of the buildings, merging them with the existing topography. As well, the natural stone facade that wrap both buildings provides a soft skin blending with the natural hillside setting.
