Preserving Modern Architectural Heritage in the Context of the Zeki Sayar House on Büyükada

Büyükada, known for its Ottoman-era palaces and pavilions, became a prominent summer destination for Istanbul’s affluent citizens by the late 19th century. Over time, the original characteristics of these houses have deteriorated, underscoring the need for preservation. This study examines how the original design of Zeki Sayar’s house meets contemporary usage needs, focusing on the preservation of both its function and form in terms of the facade and interior. Qualitative methods are utilized herein, including literature reviews, site observations, oral history, and user experience analysis. The primary objectives are to highlight the importance of preserving the original functions of period houses, assess the applicability of original design in modern contexts, and propose conservation strategies for modern architectural heritage in Büyükada, particularly regarding the Zeki Sayar House. The preservation and functional continuity of this house serve as a model for maintaining modern architectural heritage in residential buildings.
