On the European side of the Bosphorus, nestled along Yeniköy Köybaşı Caddesi, stands a historic waterfront mansion dating back to 1810. Originally owned by a French family, it changed hands in 1933 when it was acquired by Burhanettin Sezerar, a distinguished professor of Electrical Engineering at Istanbul Technical University. Professor Sezerar's contributions extended beyond academia, as he played a pivotal role in electrifying the Uskudar Tramways, Adapazarı electrical installations, and several mosques. Upon his passing in 1952, the mansion transitioned to the hands of its rightful heirs. Following a meticulous restoration, the mansion found a new resident in Hanzade Sultan, one of Sultan Abdülmecit's daughters.

The three-story mansion features balconies spanning two levels along its seaward facades, adorned with ornate wooden parapets. It gracefully extends towards the shore on the north and south sides, these extensions being elegantly incorporated into the balconies. With a total of eleven rooms and two lounges, the mansion's grandeur is undeniable. Situated below street level, the mansion's entrance is accessed via a descending staircase leading to the garden. Separating the mansion from the street is a tall perimeter wall, ensuring privacy for the tranquil mansion grounds. The northern section of the estate boasts an expansive garden, where the mansion's former boathouse once stood. Within this historical abode, you'll find thirteen rooms and seven bathrooms, each bearing witness to its rich and storied past.
