Architect Yuzo Mikami’s Traces in the Sydney Opera House

Newly uncovered primary sources—including drawings, notes, and letters—reveal the significant but underappreciated contributions of Japanese architect Yuzo Mikami to the design of Sydney Opera House. Mikami's involvement spanned three distinct phases (Utzon, Arup, and Hall periods), during which he played a key role in shaping architectural elements such as concourse beams, shell roofs, warped surfaces, and glass walls. Analysis of these materials demonstrates that Mikami’s archives are invaluable for historical and technological studies of the landmark. This research sheds light on a previously overlooked aspect of the Opera House's design process.
