A conversation with Paolo Stracchi and Luciano Cardellicchio, uncovering the hidden construction intelligence behind the Sydney Opera House.

For fifty years, the Sydney Opera House has inspired a prodigious hagiography of personalities and their legendary quarrels. Yet its operative construction decisions (especially those behind the sail-like roof) remain under-explored.

Drawing on recently surfaced documents and 5,000 Hornibrook shop drawings held by Museums of History NSW, Paolo Stracchi (University of Sydney) and Luciano Cardellicchio (University of NSW) reconstruct the exact procedures that made the sails possible (1963–1967).

The talk foregrounds Australian operative ingenuity and intellectual contributions that transformed Jørn Utzon’s vision into built form.
