Among the winners was Mirvac’s Olderfleet in Melbourne’s Collin Street, named the world’s best building 100m to 199m.

Mirvac Head of Integrated Investment Portfolio Campbell Hanan said they were “thrilled to have Olderfleet recognised by the CTBUH on this global stage”.

“It’s a testament to the collaboration between the talented visionaries at Grimshaw, our own development team and our partners, Deloitte.

“Olderfleet sets a new standard in workplace design, bringing together heritage, smart technology and show-stopping art and architecture.

“It’s a place where brilliant minds and overall wellness thrives, and it’s a very proud moment for Mirvac, as we also announce the building’s WELL Platinum Certification.”

Twenty-six awards were decided on by the international judging panel plus another 26 were chosen by the audience at the CTBUH conference in Chicago, with 130 Lonsdale Street in Melbourne picked as Best Tall Building Australia, and Prahran Square, Melbourne, taking the Urban Habitat—District-Masterplan Scale award.
