Golden Age Group has restarted construction on its $180 million office tower in central Melbourne after work on the Little Collins Street project halted when builder Roberts Co Vic went into administration in March.

The strata office project was hit by two builder failures – by that of Probuild three years ago and then by Roberts Co, which took over the Melbourne CBD project as part of the NSW builder’s fateful expansion south of the Murray. It will complete in August, rather than this month, Golden Age said.
