Rare Dual Residence with Expansive 1218sqm Coastal Holding...

Set behind a wide 20.27m frontage, this substantial coastal holding presents a rare opportunity in tightly held Semaphore South-a substantial 1218sqm allotment comprising two fully self-contained residences under one title. Just three houses back from the Esplanade, the home captures the essence of beachside living with sea glimpses, generous proportions, and an enduring sense of space that is increasingly hard to find.
From the street, the home presents with a clean, elevated coastal façade-solid and symmetrical, softened by established trees and framed by a secure frontage that hints at the scale within. Inside, the layout unfolds with impressive clarity: two residences, each flowing across two levels with their own private entries, balconies, and living zones. Ground floors are anchored by open-plan living, dining, and kitchen spaces that extend naturally to outdoor entertaining areas, while upper levels provide further flexibility with additional kitchen facilities, well-proportioned bedrooms, and direct access to balconies that draw in sea air and light.
Across the property, there are six bedrooms, four bathrooms, and four kitchens in total-one on each level-making the home exceptionally well suited to multigenerational living, extended families, guest accommodation, or investment. Each residence offers three-bedroom accommodation designed for practical, everyday living or strong rental appeal. The floor plan is intuitive and functional, with living spaces positioned for connection, kitchens thoughtfully placed across both levels for maximum flexibility, and bedrooms set privately to create calm separation from the main activity zones. Rear lane access and multiple outdoor areas further enhance usability, while balconies on both levels reinforce the home's coastal orientation.
Currently returning a combined $5,500 per month on periodic leases, the property also offers immediate holding income with future flexibility to occupy, update, or reimagine.
