The Queensland government's failure to consult with the industry before making changes to property regulations have resulted in complex and costly rules for new developments, according to the Property Council of Queensland.
Test glass proposals are due to be phased in over 12 months beginning May 1st, but the council's executive director Steve Greenwood believes that more consultation was necessary.
He said: "We estimate that for an average building in Brisbane's CBD this will add between $15,000 (£8,551) to $25,000 (£14,252) a floor.
"For a 20 to 25 storey building that adds in the order of half a million dollars to the construction cost."
His comments come ahead of the meeting of property industry experts in Melbourne next month, to discuss how sustainable and productive green buildings will become in Australia's so-called sustainable cities.
