Overview

Architectural Harbourview Entertainer with Resort-Style Living Near Balmoral

Positioned to capture uninterrupted harbour views stretching from Balmoral and Manly to The Heads and north toward Clontarf, this exceptional north-east facing residence delivers the ultimate family lifestyle just moments from Balmoral Beach and Mosman Village. Designed for effortless living and entertaining, the home offers four generous bedrooms plus a study (or optional fifth bedroom), three beautifully appointed bathrooms including a recently renovated master ensuite, and multiple living zones enhanced by soaring ceilings, double-sided fireplaces and seamless indoor-outdoor flow. The master retreat enjoys its own terrace with skylight openings and breathtaking water views. At its heart, expansive open-plan living spills onto a large undercover terrace with built-in plumbed gas BBQ, overlooking a stunning 10m x 4m pool and fully equipped cabana. A rumpus with Belgian steel bi-fold doors opens directly to the poolside, while a dedicated lounge and family living area provide flexibility for growing families. Additional highlights include a 600-bottle sandstone wine cellar, zoned reverse-cycle air conditioning, underfloor heating, high ceilings throughout, a double garage with internal access and a professionally installed in-ground basketball hoop. Thoughtfully designed with passive climate principles and built to maximise the 570sqm parcel, this is a rare opportunity to secure a substantial, sun-drenched family sanctuary in one of Mosman's most tightly held pockets.
