Held by the same family since 1953 this is an extraordinary chance to secure a truly exceptional residence. Privately nestled well back from the road with entry via Moran Street, the home enjoys serene seclusion, lush surrounds and direct access to a walkway leading to Sirius Cove Reserve and its picturesque beach. The beautiful harbour foreshore of Clifton Gardens is also moments away. - Elevated position with sweeping harbour and treetop panoramas - Segmented lounge and dining rooms with elegant timber floorboards - Ornate fireplace and captivating water views from the main living area - Full-width terrace set high above the landscape for breathtaking sunsets - Generous bedrooms with outdoor connection, two with built-in robes - Charming timber kitchen with stone benchtops and gas cooking - Refined library with stained glass windows and original fireplace - Dedicated laundry, outdoor bathroom and large single carport Steeped in history, the land was originally owned by Captain C.G.F. Blix, a Swedish mariner who constructed a stone cottage here in circa 1850 to watch ships enter the harbour. Over the decades, the original cottage evolved into a more substantial residence. A once-in-a-generation offering in one of Mosman's most prestigious waterfront pockets.
