The Bosporus Mansion Project is a renovation project of one of the independent sections of a historic mansion consisting of separate units. Encompassing 2 main floors and 1 attic floor, our aim in the project was to update the structure with contemporary elements while preserving its characteristic features as much as possible, within the flow of the plan we created based on usage needs. All electrical, mechanical, and lighting systems of the building were renewed to meet modern requirements. Over time, elements added in previous renovations were largely removed, and the building was brought closer to its original state. This approach created a harmonious contrast between the architectural and decorative features carrying the characteristics and traces of time, and the contemporary design concept we formulated, complemented by artworks.
