Exchange Plaza, Skyscraper in Perth, Australia

Exchange Plaza is a 40-story skyscraper standing 146 meters tall with a steel frame and fully glazed curtain wall system. The exterior wall recedes at the upper levels, creating a stepped profile that defines its skyline appearance.

The project emerged during the 1980s property boom through a partnership between Westpac subsidiary Australian Guarantee Corporation and Japanese firms C. Itoh and Shimizu. This international collaboration reflected Perth's expanding global connections during that era.

The tower stands on land leased for 135 years from the Weld Club, a gentlemen's club at the corner of Barrack Street and The Esplanade. To keep the club's historic character, the developers sourced century-old bricks and tiles to join the tower's base to the club complex, and rebuilt the club's bowling green after excavating it for the car park.

The building contains 33 commercial office floors, basement parking, and a 150-seat conference center. Most of the interior spaces are private offices and not open to casual visitors.

The building's rooftop serves as a launch site for fireworks during the annual Lotterywest Skyworks festival. This position makes it a notable focal point in the city's skyline during the celebrations.
