Project Eliza Apartments Location: Sydney Architect: Tony Owen Partners Architects BACK TO THE FUTURE While the sandstone exterior of this new apartment building ﬁts within the historical context of the inner-city streetscape, the building methodology and architecture is pure 21st century It’s rare for architects to get the opportunity to design a new benchmark building in the inner city, so when a prime park-side site became available in Sydney’s Elizabeth Street, there was intense interest in the development. And architect Tony Owen did not disappoint. With a design he describes as challenging, Owen set out to push the boundaries using parametric design tools to create a sustainable, new landmark for the CBD. “While this was always going to be a very contemporary apartment building, it still needed to sit within the historic context of the location,” Owen says. “The site is opposite St Andrews Cathedral and close to the Great Synagogue and 74 SEARCH | SAVE | SHARE AT trendsideas.com the Sheraton Hotel, all fine examples of Sydney’s beautiful heritage architecture.” The building – Eliza Apartments – consequently presents a contemporary expression of the principles embodied in the surrounding buildings, including the traditional bay window common to buildings in Elizabeth and Macquarie Streets. “Traditional contextual materials, such as sandstone and steel, are also used in a modern and challenging way,” the architect says. “We utilised parametric 3-D computer modelling to mould the facade to the changing environmental conditions on the skin. The profile of every level is different, as the design responds to the differing unit plans, views and sun on each level.” Below:Eliza Apartments in the Sydney CBD was designed using parametric modelling to create a fluid, undulating facade where every floor is different.
