Overview

Private Family Sanctuary on 670sqm in Exclusive Harbour-Side Cul-de-Sac

Wrapped in walls of glass and immersed in tranquil greenery, this expansive multi-level residence presents as a private sanctuary on the edge of Sydney Harbour. Positioned in an exclusive cul-de-sac on the fringe of Balmoral Park, the home commands a substantial 670sqm parcel and delivers approximately 380sqm of internal living, thoughtfully designed to capture a prized northern aspect with winter sun and summer comfort enhanced by external shutters throughout. A series of beautifully scaled living and dining zones unfold across both levels, creating flexibility for both everyday family life and large-scale entertaining. Formal and informal areas connect seamlessly to wraparound terraces, alfresco spaces and the heated swimming pool, while the window-framed kitchen with generous eat-in island forms a natural gathering point, linking effortlessly to the outdoor BBQ terrace and landscaped surrounds. Accommodation is generously proportioned and well-zoned. The upper-level master retreat enjoys a full-width private balcony, walk-in dressing room and ensuite with bathtub, complemented by an adjoining study. Additional bedrooms are spacious, including a ground-floor guest suite with direct yard access. Extensive built-in storage, ducted air conditioning and a considered floorplan ensure comfort and practicality throughout. A basement double garage is accompanied by a workshop, wine cellar, bicycle storage and additional storeroom, while a large solar system with home battery, rainwater tanks and EV charging enhance sustainability.
