Mirvac's Olderfleet office tower at 477 Collins Street in Melbourne received Australia’s first core and shell pre-certification at the Platinum level.

Mirvac has extended its WELL Building Standard leadership by scoring Australia’s first core and shell pre-certification at the Platinum level for its upcoming Olderfleet office tower at 477 Collins Street in Melbourne.

Precertification allows developers to understand early on in the construction process whether intended designs will be conducive to a WELL rating. In the case of Olderfleet it’s a necessary step, as anchor tenant Deloitte has WELL core and shell certification as one of its key requirements for the new space.

“The wellbeing of our people lies at the heart of why this is so important to us and it’s great Mirvac shares our commitment to provide a healthy, sustainable work environment,” Deloitte chief executive Cindy Hook said.

“We’re delighted our future Melbourne home is Australia’s first building to achieve Platinum core and shell pre-certification and demonstrates our commitment to have one of the most sustainable and innovative workplaces of the future.”

Mirvac head of office and industrial Campbell Hanan said gaining WELL core and shell certification would make it easier for Olderfleet tenants to get WELL tenancy ratings.

“A WELL certified Core and Shell will contribute to a healthy working environment for the future workers, creating an environment that educates through design, form and function,” he said.

The Olderfleet building, which recently began construction, is a new 40-storey office tower that will emerge from behind the 1880s facades of heritage buildings along Collins Street in the Melbourne CBD. Mirvac has also committed to a 6 Star Green Star rating and a 5 Star NABERS Energy rating. It is due for completion in 2020.

Credits Mirvac is targeting across WELL’s seven categories of air, water, nourishment, light, fitness, comfort and mind include:


  • Exploring the use of unique UV radiation for cleaning services as well as using safe green cleaning products and microfibre cloths.


  • The internal tenancy stairwells have been designed to encourage tenants to use them, as opposed to the lifts. This includes making them highly accessible, having good lighting and adding a glass façade so that people can see others using the stairs.
  • Exploring the use of wellness monitoring stations for the building, which will include BMI and health checks.


  • Acoustic design of the building has been considered to reduce noise intrusion into the workplace from external areas and noise absorptive ceiling tiles will reduce noise from within the tenancy.
