QV.1 is a 40-story modernist skyscraper, completed in 1991. The building is presently the third-tallest building in Perth. This project was designed by architect Harry Seidler and has won numerous awards for its innovative design and energy efficiency. The tower has a reinforced concrete core, which bears lateral forces -- including wind loading. The perimeter of the building features reinforced concrete support columns, and there are no internal columns between floors. The QV.1 was criticized for being Perth's ugliest building, as well as a giant Lego block, but architect Harry Seidler described it as the best building he had ever built.

Woodside Plaza is a 29-story skyscraper in Perth. The tower serves as the headquarters for Woodside Petroleum, and it incorporates several energy-efficient design features. When completed in 2004, the building was the first premium-grade skyscraper completed in Perth. It is currently the sixth-tallest skyscraper in the city. The tower was designed by architects Kann Finch Group. It features 251 basement car parking bays, a bar on the ground floor, shops, a 120-seat auditorium on the mezzanine level and a fully-equipped gym. The tower is noted for its efforts in efficient energy use.

Central Park is a 51-story high office tower. At its base is St. Georges Terrace and on the roof is a communications mast. Upon its completion in 1992, the tower became the tallest building in Perth. It is also currently the seventh-tallest building in Australia. The building is constructed with a composite steel and concrete frame, and has several setbacks on the outside, so the upper floors are much smaller in area than lower levels. The base of the building features a small park, for which the tower is named. Since its completion, Central Park has been regarded as one of Perth's leading premium office towers.

140 St Georges Terrace is a 30-story skyscraper, opened in 1975. The tower was known as the AMP Building or AMP Tower. This skyscraper features an interior service core design, with the concrete core containing elevators and two stairwells. The perimeter of the square, cross-section tower, features load-bearing columns, allowing the office floors to remain fairly column-free. The building has one service elevator and twelve passenger elevators. The low-rise and high-rise portions of the building are clearly visible on the exterior of the building, as they are separated by an attractive atrium level.

The BankWest Tower is a 52-story office tower, completed in 1988. It has a communication antenna on its roof. Now, it is the second-tallest building in the city. The concrete tower has a distinctive profile, with a triangular plan. The tower was designed by architects Cameron, Chisolm and Nicol. The major parameter given to them in the planning of the building was that all office areas should face and have excellent views of the Swan River. Working within this brief, they selected a triangular cross-section of the tower because it lent itself to open-plan office layouts by allowing natural light to reach most parts of the working floors.

Allendale Square is a 32-story skyscraper. When opened in 1976, the building became the tallest completed building in Perth. The tower is located on a large site, however, the tower itself only occupies 25% of this land area. Designed by architects Cameron, Chisolm and Nicol, the building is rotated 45 degrees relative to St Georges Terrace, in order to secure a plot ratio concession from the Perth City Council. The walls of the tower are stepped in plan, creating V-shaped protrusions along each face. In order to maximize views towards the Swan River, the building has windows only on the North and South-facing sides of these steps, and the remainder of the tower is clad with aluminum. The building has been described as a fine example of high-rise architecture, timeless, one of Perth's most prominent office buildings, a building of considerable elegance, and a good building representing its time.

Exchange Plaza is a 40-story skyscraper, completed in 1991. This building is the state headquarters of the Australian Securities Exchange. Currently, it is the fourth tallest skyscraper in Perth. It was designed by architects Peddle, Thorp and Walker. It is a steel-framed structure with precast concrete floor panels. The exterior of the building is fully glazed with curtain walls, which step back at the upper levels. The unique blue glass was produced in a one-off batch by Pilkingtons Australia. The building features a 150-seat conference center and uninterrupted river views from most levels -- across Perth Water and West, all the way to Rottnest Island.
