Mirvac has commenced construction on a new, 40-storey office tower in Melbourne.

Designed by Grimshaw, the defining feature of Olderfleet at 477 Collins Street is a ‘vertical village’ concept. The tower has been split into three separate modules to express key internal workings of the building and make strong connections with the heritage context. The tower will rise from the unique 1880s façades of the heritage buildings along Collins Street.

“Olderfleet presents an exciting opportunity to integrate a very modern commercial tower and forward-thinking workplace technology with one of Collins Street’s most important pieces of heritage fabric,” says partner at Grimshaw, Neil Stonell.


The heritage buildings that sit on the site, which were built between 1887 and 1889, will remain intact. These are the work of a number of architects, with the result being a varied collection of styles – from Gothic to Romanesque Victorian architecture. Although the façades will remain largely untouched, an extensive refurbishment and modernisation of the interiors will take place in order to create boutique office and retail space.

Olderfleet will boast one of the largest office lobbies in Melbourne, with a 30-metre-high glass atrium connecting the heritage buildings to the new office tower. This will provide a unique view of the heritage façade. This space will include a lobby cafe and a business centre with meeting rooms on the lower-ground floor.


The office tower will use large floor plates for flexibility with doors to terraces looking onto spacious outdoor spaces. This design allows for outdoor terraces on each village.


Olderfleet is committed to a 5-star Green Star rating, a 5-star NABERS energy rating, and the achievement of Platinum WELL certification. 

Construction is due to be complete by 2020.
