Rare Coastal Restoration Opportunity

Positioned within one of Semaphore's most tightly held coastal pockets, this c.1910 character home presents a rare opportunity to secure a substantial landholding and create something truly special. Set on approximately 487sqm, the property offers endless potential for those with vision, whether that be restoring its original charm, undertaking a significant renovation, or exploring redevelopment opportunities (STCC).
Rich in history and character, the home stands as a reminder of Semaphore's early architectural heritage, waiting for its next chapter to be written. Opportunities to secure a property of this era, on a well-sized allotment and just moments from the coastline, are becoming increasingly difficult to find.
Adding further appeal is the valuable rear lane access, providing flexibility and convenience that is rarely available in such a sought-after beachside location. Whether you're a renovator, builder, developer or buyer searching for a long-term project, this is a property that offers genuine scope to add value and create something remarkable.
