Architecture can often be best understood, and appraised, by a ‘but for’ test: what might have been there but for the realised design? What were the other options? What would the path of least resistance have been?
At 9 Cremorne in Melbourne, the answer might have been a bog-standard ‘glass box’ . By developing an innovative facade using custom-designed aluminium mesh, however, has taken an altogether more thoughtful approach.
“The anodised facade creates an ephemeral effect – a shifting curtain backdrop to the heritage experience at ground level, with a beautiful translucency at night,” says Quino Holland, Co-Director of Fieldwork.
The ‘second skin’ is made up of operable screens designed to work with the changeable Melbourne climate. Constructed from bespoke, expanded aluminium mesh, this skin is designed to reduce heat load and glare. Users are able to customise and adapt the building envelope in response to sunlight, natural ventilation, views, glare and temperature.
The approach means that the building can employ a full-height, slab-to-slab glass facade without the associated climatic difficulties. The harsh northern and western sun, for example, can be shaded when necessary, all the while maintaining some visibility through the mesh.
Internally, the glazing contains manually operable louvres that can be customised independently of the screens, “allowing each floor to purge heat at the end of the day and cross ventilate when a cool change arrives,” as Holland explains.

With the focus on operability, the form itself remains rectilinear. It also maintains a slight but important distance from the heritage aspects of the original building, whose more significant western facade has been restored in consultation with Bruce Raworth Heritage. Elsewhere, the simpler northern facade was structurally unsound so the designers chose to demolish and rebuild using refurbished steel windows and original brick.
On the level of detailing, Fieldwork has used red mortar with a raked joint to express differences between the original and rebuilt sections of brickwork, while an existing downpipe recess is reworked as a shadow gap. “We wanted to show, to the keen eye, the division of original and reconstructed architecture,” explains Holland.
Landscaped terraces add some much-needed greenery, while a rooftop entertainment space caters to a community atmosphere. The building achieves a 5-star Greenstar rating, with water storage and filtration provided on-site as well as solar photovoltaic panels on the roof and digital displays to track water and energy use.
