Clifton Gardens’ most exceptional residence and arguably one of Sydney’s finest, this five-storey estate represents the pinnacle of contemporary luxury and timeless elegance, capturing sweeping views of both the Opera House and Harbour Bridge - a rare perspective available only from select vantage points across Sydney. Originally designed by Susan Rothwell LFRAIA, the home has undergone an extensive year-long renovation, sitting on an expansive 1792sqm parcel. Every detail has been meticulously considered - from French oak herringbone flooring to handcrafted tiles, brass-inlay cabinetry, upgraded fireplaces and decorative French windows - creating a seamless balance of contemporary style with respect for its original details. With glamorous formal and casual entertaining spaces and alfresco terraces, high mature hedges ensure exceptional privacy while enhancing the lush, landscaped setting. Resort-style amenities include a championship tennis court (accessible via a Wimbledon-style tunnel and private coach entry), an infinity pool, and a versatile gym/fitness area. Every detail speaks of refinement, while a private cinema and two upgraded kitchens all elevate the living experience. An incomparable opportunity within the tightly-held Clifton Gardens enclave, where homes of this calibre are rarely offered to market.
