Blues Point Tower, Residential building in McMahons Point, New South Wales, Australia

Blues Point Tower is a 24-level apartment block in McMahons Point, rising 83 metres and containing 144 apartments. Designed by Harry Seidler in the Internationalist style, it has French balconies rather than the originally planned internal terraced balconies, a change made in 1959 to comply with floor-space-ratio rules.

The building was completed in 1962 by architect Harry Seidler and Associates and was then Australia's tallest residential structure. It held this distinction until another building surpassed it in 1970.

Blues Point Tower is often called one of Sydney's ugliest buildings, and public figures have called for its demolition. In 1993 North Sydney Council added it to its local heritage register as a "Conspicuous, though unpopular, example of Internationalist style". Architect Harry Seidler defended it: "one of my best buildings".

The building is located near North Sydney with good access to transport options and urban services in the surrounding area. Keep in mind that this is a private residential building and is not open to the public for tours.

In February 2011 a 6-metre maritime radar was mounted on the roof. The tower was the first high-rise apartment building in Australia to be strata titled, and its site office during construction was an 1870s Victorian villa called Bellvue that had stood on the same land.
