ARCHITECT YUZO MIKAMI’S TRACES IN THE SYDNEY OPERA HOUSE

Yuzo Mikami (1931–2020) was a Japanese architect who participated in the design project of the Sydney Opera House. Despite being a key member, he has not been sufficiently appreciated. This paper aims to clarify Mikami’s design activities using newly discovered primary sources: drawings, notes and letters. Mikami joined this project thrice, which we named the Utzon (1958–61), Arup (1962–64), and Hall period (1967). Then we analyzed four architectural elements: the concourse beams, shell roofs, warped surface, and glass walls. This research will demonstrate that Mikami’s archives are crucial sources when conducting historical and technological analyses of the Sydney Opera House.
