In the design of the cafe and restaurant located on the basement and ground floors of a historical wooden mansion on Istanbul’s Ihlamur Yıldız Slope, it is aimed to use it as a study lounge area where university students can visit daily. A palette of simple, youthful and inviting materials were chosen which would not interfere with the high ceilings and window wood works on the upper floor of the mansion. Different sitting groups, working areas and barista area were designed to in order to sit with a laptop. On the lower floor, there are high seating areas for quick meals and an open kitchen that serves street food. These two spaces, which used to be connected via indoor stairs, were considered separately by the customer but are operated under the same name. Spatial integrity has been achieved by preserving the palladian mosaic flooring that transmits the lower and upper floors to each other, and by using terrazzo-patterned ceramics, which are the continuation of this mosaic image in the wet areas.
