Behind the Build: Who Actually Built Sydney Opera House?
Sydney Opera House is one brand on the marquee — Sydney Opera House — but the project runs on named specialists (ARM Architecture, Arup, Müller-BBM, Steensen Varming and more). Every supplier link below is verified with source_url + quote.
TL;DR
Bottom line: Sydney Opera House looks like one marquee name (Sydney Opera House), but at least 6 verified system slots are served by named B2B suppliers — elevators, structure, facade, MEP, and more — each backed by a published source. See the slot→supplier table and source quotes below.

You know Sydney Opera House. You might know the operator — Sydney Opera House. But Sydney Opera House is not one company’s product; it is an assembled system. Each system slot below is a different brand’s specialty — every line backed by a published source.
