3 factors that set the Mason Road project apart
- Project scale: The Mason Road development was one of the larger standalone residential projects we have worked on. Located in Box Hill, a significant growth precinct in Sydney’s North West, it brings together substantial apartment numbers and a multi-building footprint, all assessed in a single report.
- Same-day draft: Work started as soon as the engagement was confirmed, and the draft EDC Report was issued that same day. The final report followed the next day, prepared to the AIQS practice standard on the NSW standard form for development costs exceeding $3 million.
- Less back-and-forth for the client: The final report was issued without further revisions or review rounds, so the project team could move straight to lodgement. A quick turnaround with no back-and-forth meant the DA lodgement was never held up waiting on the cost report.
