This two-stage, $73.7 million Optima Centre development is one of the largest suburban office developments in Western Australia, with more than 16,200m2 NLA constructed across two separate towers, 519 car spaces and excellent end-of-trip facilities.
A joint venture between Macquarie Bank and the ABN Group, it achieved a 4 star Green Star (V2 Design) rating and a 4.5 star NABERS rating.
Stage One, worth $10.7 million, consists of a four-storey, 2,653m2 (NLA) office tower. Sixty percent of the car park structure (90 parking bays), fire tanks and sprinkler valve room needed to be completed before occupation.
After 75 weeks of construction, the tower was completed in May 2009 and occupied by ABN Group and Cannon. Stage Two, worth $63 million, consists of a seven level, 13,600m2 (NLA) office tower that includes 429 car parks and base build generator—all constructed while Stage One was fully occupied.
After 80 weeks of construction (16 weeks ahead of schedule), the tower was completed in May 2010 and occupied by the WA State Governments Building Management and Works Department.
