Highcliff
Highcliff is a 252.4-metre tall skyscraper located on a south slope of Happy Valley on the Hong Kong Island in Hong Kong. The 75 storey building's construction began in 2000 and was completed in 2003 under a design by DLN Architects & Engineers. It was the Silver Winner of the 2003 Emporis Skyscraper Award, coming in second to 30 St Mary Axe in London. The tower is the tallest all-residential building in Hong Kong and the 95th tallest building in the world when measured to the highest architectural feature.
Highcliff is remarkably thin for such a tall building. It has a slenderness ratio of 1:20, and is one of the thinnest buildings in the world. Because of this, a passive wind damper was fitted to the top. This wind damper was the first of its kind for a residential building anywhere in the world. This was installed because of the number of typhoons which affect Hong Kong in the late summer.
Due to the visual effect of its proximity to The Summit, another very thin and tall building, the two together are often referred to as "The Chopsticks".
