Depicting a first impression of grace and elegance whilst beholding a beautiful history spanning over multiple generations, this c1896 Victorian residence and its very rare 1,170sqm slice of seaside Semaphore is ready to change hands for the first time in 56 years.

With a rich history that cannot be recreated - and one of only two structures remaining with a railed rooftop lookout - this is your once-in-a-lifetime chance to own an iconic piece of Semaphore's past with an incredibly bright future...
Property features:
•Three self-contained units or one immense family home
