Cadonia Australia to project manage tenders for additions to Harry Seidler designed building

In recent months Cadonia Australia has been working on the design and council approval for the addition of covered walkways on a Harry Seidler designed building in the Sydney suburb of Edgecliff.


Harry Seidler is an icon of Australian architecture and often credited with bringing modernism to Australia. He is best known for changing the skyline of Sydney’s CBD and contributing useable, public spaces to the city. Australia Square (1961), the world’s tallest light-weight concrete building at the time, is a case in point. For more than 50 years, Seidler produced distinctive, bold modern architecture, including houses, apartments, offices and embassies—in Australia and internationally. The 8 x 3 bedroom residential apartment block was originally designed in 1966 by the acclaimed Australian architect Harry Seidler (1923–2006).


The proposed design created by Cadonia Australia for the additions to the apartment complex that was built in 1966 received a Development Application approval from Woollahra Council on 5 August.


Construction of the six walkways will provide residents with under-cover entry from the street pathway to their apartments and also significantly diminish the impact of unwanted residue left by seasonal flying bats. Part of our brief was to minimise the visual impact of the additional roofing, with a number of designs presented to residents.


Cadonia Australia has now been appointed to project manage the tender stage of construction.


Our 3D rendering team produced a series of images on the structural design for this project, including these two images that capture the walkway design looking from the front of the apartments on Edgecliff Road. The proposed design for some of the additional roofing over the stair sections is visible in the background on the image below.
