Travel down the bank of escalators between York Street and the main concourse level at Wynyard Station and you’ll find the winner of the National Trust’s inaugural Outstanding Project of the Year award. This is the first time the category has been part of the National Trust Heritage Awards, which has been running for 24 years.

Interloop – created by Australian contemporary artist Chris Fox for Transport for NSW – is a 50-metre-long suspended installation built from salvaged Wynyard Station wooden escalator treads that long-time Sydney commuters will remember fondly (or less fondly if you wore high-heels).

It was one of the projects recognised by the national body that promotes the conservation and restoration of, and access to, Australia’s unique natural, cultural and Indigenous heritage. Other winners include the Westpac Long Gallery in the Australian Museum on William Street and the Hyde Park Barracks Stonework Remediation project.

Australian broadcaster, comedian and Modernism lover Tim “Rosso” Ross picked up the Advocacy Award. And the fourth edition of the conservation plan for the Sydney Opera House, “Respecting the Vision: Sydney Opera House – a Conservation Management Plan, 2017”, was also celebrated with the award for education and interpretation for its policies guiding change.

“[The 2018 winners] represent some amazing achievements on the part of organisations and individuals who are dedicated to conserving, revitalising, inspiring, educating and exciting everyone about our built and natural heritage,” says the CEO of the National Trust of Australia (NSW) Debbie Mills.

Although they didn’t win, the [Griffiths Tea Building in Surry Hills – inhabited by Chin Chin (read Broadsheet’s story about the building project here) – was shortlisted, as was the restoration of the Greenwich Baths facades and the repurposed South Sydney nurses’ quarters, which has become an artistic workshop and gallery space near Green Square, called the Joynton Avenue Multi Arts Centre.

This is the 24th year the awards have been presented by the National Trust, a not-for-profit organisation that owns and manages more than 300 heritage sites. The awards are part of the Australian Heritage Festival, which runs until May 20.
