1690sqm of Land with Approx. 35m Frontage – Renovate, Extend or Explore Development Potential (STCC)

It is not often that a landholding of this scale becomes available in Seacliff Park - and rarer still when it enjoys a position bordering Gilbertson Gully Reserve.

Set on an expansive 1690sqm allotment with an approximate 35m frontage and a significant portion of usable flat land, this is a property that invites big thinking. Whether you are searching for a family home to renovate and enjoy, or considering the future potential for four or even five dwellings (STCC), the possibilities here are substantial.

Positioned at the end of a quiet cul-de-sac with no through traffic, the setting feels wonderfully removed from suburbia while remaining moments from schools, shopping, Westfield Marion and the coastline. It is a true life amongst the gumtrees - where kookaburras call, gum trees sway and the occasional koala or kangaroo may wander by.

Built in 1959, the existing double-brick home is solid in its construction and beautifully placed on a generous flat pad, elevated to capture a leafy outlook across the surrounding treetops. Large north-facing windows flood the home with natural light, enhancing the sense of warmth and connection to the landscape.

The current home comprises three generous bedrooms, two with built-in robes, while the third offers flexibility for a study nook if desired. An open-plan kitchen, dining and living area forms the heart of the home, while the centrally positioned bathroom, laundry and separate toilet create a practical footprint for those considering a renovation or extension in the future.

To the eastern side of the allotment, a substantial area of level land surrounds the large existing shed, opening the door to a range of possibilities. Imagine children playing across sprawling lawns, a future pool framed by treetop views, an impressive extension, or a longer-term development outcome (STCC).

Originally formed from two separate allotments that were historically merged, the size, scale and configuration of the land may also lend itself to future subdivision or redevelopment, subject to the necessary consents.

Whether you choose to renovate and create a forever family home, extend further, add a second storey (STCC), or investigate the site's development potential, this is a purchase that can be made with both lifestyle and long-term vision in mind.

A rare offering in a tightly held pocket, surrounded by nature yet close to every suburban convenience, this is Seacliff Park opportunity at its most exciting.

Zoned for Seacliff Primary School and Seaview High School, and directly beside Gilbertson Gully Reserve, this is a property that truly offers space, serenity and endless potential.

Inspections are highly encouraged.
