The Arch is an 81-floor 231-meter (758 feet) tall skyscraper completed in 2006 located in Union Square.
It is the third-tallest residential building in Hong Kong, consisting of four towers: Sun Tower, Star Tower, Moon Tower, and Sky Tower.
The Star Tower is connected to the Moon Tower, while the Sky Tower is connected to the Sun Tower. The Sun and Moon Towers join at the 69th floor and the floors above to form an arch, hence the name “The Arch”.
Sun Hung Kai Properties, the developers for the project, was criticized for its sales tactics at The Arch in 2005. The company was accused of the practice of “internal sales” of uncompleted units, the absence of sale price-lists, and also for hyping sales for flats in The Arch by announcing inflated prices (per square meter) achieved.
