Sources expect private investment company MaxiCity to make about $50million from the 22-level building at 357Collins Street, which was the home of the ASX during the heady market boom and bust of the 1980s.
The 41-year-old building sat vacant for almost a decade after the ASX moved to 530Collins Street.
It was slowly extended earlier this decade, although a substantial interior renovation is incomplete.
The building’s next owner will have to pay for any continuing works before the building can be put to the market for lease.
Colliers International managing director John Marasco is marketing the Collins Street building with Matthew Stagg. He said the 21,455-square-metre office will be sold with vacant possession.
