The Cullinan (Chinese: 天璽; Cantonese Yale: Tīnsáai) is a residential complex located in Hong Kong's Union Square. This prime waterfront residence has glass curtain walls and sweeping views of the Victoria Harbour. The glass facade gives the twin towers a futuristic look, matching the design language used on the nearby International Commerce Centre.
This complex was named after the 3,106 carat (621.2 g) Cullinan Diamond found in 1905; the largest gem-quality rough diamond ever found, whose constituent cut diamonds are found in the British Crown Jewels and Elizabeth II's jewels.
During development under Sun Hung Kai Properties, the complex went by Kowloon Station Development Package 6 and Union Square Phase 6. Both towers of The Cullinan complex, called The Cullinan North Tower and The Cullinan South Tower, are Hong Kong's tallest residential towers at 68 stories and 270 metres (886 feet). They were completed in 2008 and 2009 respectively.
The Cullinan complex was proposed at only 45 stories up until the cancellation of Union Square Phase 5. After Phase 5 was dropped, the Cullinan Towers were proposed at the current 93 floors instead. The penthouse apartment units are located on the top floors of the building. According to Time magazine, it "could well qualify as the world's most expensive apartments."
