The refurbished building is the final piece in the redevelopment of an entire city block on Sydney’s dress circle, Circular Quay, orchestrated by the City of Sydney.
The first was the upcycling of Quay Quarter Towers, an existing 1970s office block given a stunning new cantilevered skin, for which it won the World Building of the Year in 2022. Then came the restoration of laneways for restaurants, cafes and bars in association with the conservation of the old wool store Hinchcliff House.
During years of research into 33 Alfred Street, Morel’s team found only three examples of renovations to early modern glass and curtain wall buildings, all in the United States.
These included the United Nations’ Secretariat Building in New York, which was originally built with clear glass and had to be reglazed with reflective glass to manage overheating, and Lever House, the city’s first all-glass building.
“All those examples told us that there was room to improve the amenity for the building’s occupants, but it was important that we retain the original strong silver columns, the tartan patterning of the aluminium framing and the glittering gold glass panels,” Morel said.
“We set forth a process that was very rigorous and methodical because we knew that people loved this building, and we wanted to make sure its character was maintained.”
As a result of the many workshops convened with city planners, heritage advisors and engineers came the idea of taking the original window patterning and flipping it upside down.

Glazes for the exterior wall tiles were developed specially by the Netherlands’ oldest ceramics company, Tichelaar, in consultation with the design team, through an extensive sampling and mock-up process to reinterpret the hues and iridescence of the original glass mosaic tiled walls.

“What ultimately the design has achieved is maximising natural daylight, with floor-to-window vision glass still respecting the gold tartan or gold spandrels along the slab edge,” said Nicholas Wilkinson, Dexus’s general manager of office development.
Dexus inherited the project when it acquired AMP Capital in March 2023, continuing the relationship with the project’s head contractor, Built.
The refurbished skyscraper is jointly owned by Dexus and Mirvac. Commercial tenants – mostly leading legal firms – are expected to move in by late 2025.
Wilkinson estimates the renovations shaved 20 to 30 per cent off the comparable cost of a rebuild.
Lord Mayor Clover Moore said the rejuvenation of the former AMP building was wonderful, thoughtful and sympathetic.

“Construction is responsible for nearly 20 per cent of Australia’s carbon footprint, so limiting the impacts of demolition and construction is critical to reducing our emissions,” she said.
“By pursuing a refurbishment rather than a knockdown rebuild, AMP will have saved tons of carbon emissions.”
The NSW Heritage Council will decide this month whether to add the building to the state heritage register.
