Highcliff is a luxury residential building located on a south slope of Happy Valley on the Hong Kong Island. At 252.4 metres (828 feet) and 75 floors, it is dubbed as the tallest all-residential building in Hong Kong and the 95th tallest building in the World when measured to the highest architectural feature.
The 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. It was also named Residential Development of the Year by the South China Morning Post/Harper's Bazaar StyleAwards in 2006.
The tower is formed from a pair of intersecting oval cylinders which provide sweeping views of the city, Victoria Harbour, and the lush mountain. Built on a steep slope, the main entrance of the building is actually on the ninth floor.
There are only a total of 131 residential units, with just two homes per floor. The top four residential floors of this building are single units, and include a steam room, sauna, a library, two jacuzis, four bedrooms, five bathrooms (one with separate his and hers toilets) and a maid's room.
Another remarkable feature of Highcliff is its "thin" architecture. To protect it from the numerous typhoons that pass by Hong Kong yearly, a passive wind damper was fitted to the top of the building. This wind damper, which is actually a series of water tanks at the top of the building that reduces the amount of swaying in strong wind, was the first of its kind for a residential building anywhere in the world.
Highcliff and the nearby The Summit, another very thin and tall building, are often referred to as "The Chopsticks".
