In February, The Urban Developer sat down with the design and development teams behind Australia’s largest mixed-use project to gain a greater understanding of its conception. Since then, we’ve seen this development gain strong traction with potential tenants (since committed), Multiplex have been appointed and construction has commenced, which is due for completion in late 2019.
In our latest update we’ve gained an insight into what exactly goes into the construction of a project with such monumental scale.
