Interior Space and Exhibition Design Exen Istanbul Show Flat by Yelin Evcen & Gönül Ardal Gonye Proje was commissioned to design a show flat on the top floor of a skyscraper in Istanbul by Sur Yapi, a leading construction firm in Turkey. The brief was to create a living space that was full of light and transparency with minimum solid blockages. Integrated sitting and dining areas are slightly separated from eachother by using different materials on the floor. Since it is a show flat, a color scheme that would address the majority was chosen. Gray, brown and white are used as base colors, various secondary colors are used in different rooms to emphasize the roles of the rooms.
