108 St Georges Terrace, Office high-rise in Perth, Australia

108 St Georges Terrace is a 52-story high-rise with a distinctive triangular footprint and stepped front facade in Perth. The design maximizes natural light and creates corner office spaces, while the building rests on 43 reinforced concrete and steel piles with a 16-meter-deep basement below.

The high-rise was completed in 1988 and was initially Perth's tallest building. It held this position until 1992, when Central Park was finished and surpassed it in height.

The building incorporates the preserved facade and main foyer of the former Palace Hotel, showing Perth's commitment to keeping pieces of its architectural past. When you enter the foyer, you can still see how this historic layer has been woven into the modern structure.

The tower stands at the corner of William Street and St Georges Terrace, with its main entry on St Georges Terrace. The basement reaches sixteen metres deep behind a diaphragm wall built to keep water out, and 43 belled concrete and steel piles carry the structure. The Palace Hotel's retained facade and foyer sit at street level.

In April 1987, while the tower was still under construction, five men entered the site illegally and parachuted from the top in the early hours of the morning; they were arrested. The building rose at about one floor every eight to ten days.
