“This is the plan to fully realise Joern Utzon’s vision for the building by creating an interior that is worthy of its sublime exterior. It involves nothing less than a complete rebuilding of the problematic Opera Theatre, with more room, better sound and sightlines, and a richly conceived decorative scheme. The renewal project would take seven years, employ up to 3000 people and cost an estimated $900 million. Some reports have rounded up the figure to $1 billion.”
