Square in Australia

Officially christened the Tower Building, the iconic tower of Australia Square was the first known skyscraper in Sydney.


It was considered as the world's highest concrete building at the era it was constructed. Located at 264 George Street, the Tower is roughly 170 meters tall and occupies one quarter of the area of the block.


Australia Square was designed as a multifaceted office and retail complex in the heart of the business district of Sydney, Australia. Envisioned by the genius of Harry Seidler & Associates, it remains an iconic sight and is considered as an architectural symbol. It has even been described as the one of the most beautiful buildings in Australia.



Australia Square won the Sir John Sulman Medal for its innovative and appealing design. Originally designed for 58 floors this was however reduced to 50.

The tower is constructed using lightweight concrete, with a number of projecting vertical columns narrowing into the summit and sustaining a combination of interlocking rib-structured reinforcement and radial support beams. Forty-two meters in diameter, the central core of 20 meters, contains the elevator shafts, emergency stairwells as well as the service conduits.

Each floor is shaped like a donut, with a span of 11 meters to the perimeter windows. Construction time for each floor was clocked at five working days marking as a new standard in office tower construction. The Australia Square Tower Building held its height record for nine years.

Another noteworthy feature of the Australia square is the revolving restaurant called The Summit at the 47th floor with an observation deck at the 48th floor. The building also contains one of Sydney's biggest basement car parks with slots for 400 vehicles. The grounds also boast of an extensive public open space decorated with fountains.


There are a number of entrances to the retail grounds in the lower ground level of the Tower, which include a post office as well as several food outlets.
A recent $12 million dollar revamp on Australia Square upgraded the lighting in the lobby to highlight the picturesque Nervi ceiling and replaced the previous Pebblecrete pave in the plaza with Italian porphyry stone walkways.


The most noticeable aspect of the project is the latest artwork in the lobby. The tapestries of the previous Le Corbusier and Vasarely have been removed and have been replaced by a vast, vibrantly colored mural. The mural was designed by the celebrated New York artist Sol LeWitt.

Several critics argue, however, that an aboriginal artwork would have been more stunning, highlighting Australia Square’s rich Australian cultural heritage. Nonetheless Australia Square is considered one, if not the most, progressive and ground-breaking tower for its time, a true marvel in terms of creating a genuine civilized civic space in the heart of Sydney’s’ sprawling cityscape.
