Properties with either a frontage to, or views of, Sydney Harbour are some of the most prestigious that money can buy. An address in the elite enclave known as the Northern CBD (Central Business District) - home to billionaires, celebrities and leaders of state - is a sign that the owner has 'made it'. As Colin Griffin of Colliers PRD puts it, 'this is the blue riband residential belt of city real estate. Sydney Harbour is the main attraction - the best apartments must have a view, and it is preferable to overlook one or both of the icons, the Harbour Bridge or Opera House. 'Homes here are spacious and uncompromising in quality. Most have resort style pools and facilities, concierge and secure parking. The Northern CBD is also within close walking distance of Sydney's prime office precinct, a further drawcard for high-end corporates looking to house their executives. The strength of this premium rental market has also underpinned the area's growth.' Mr Griffin says high-net-worth clients from Hong Kong are particularly keen to buy quality apartments in these locations. The penthouse at Stamford Marque, offered for sale with Foreign Investment Review Board approval, is a rare opportunity. Spanning three extensive levels, the 365-square-metre interior blends seamlessly with outdoor living areas of 176 square metres. The design of the floor space takes advantage of views across Sydney Harbour Bridge and beyond to the Blue Mountains. Nearby are the historic precincts of Millers Point and The Rocks, tranquil parklands of Observatory Hill, the CBD and Circular Quay. This brand new penthouse is offered for sale at A$7.6million fully furnished, through Colliers PRD.
