One Canada Square
One Canada Square, commonly referred to as Canary Wharf Tower, is a skyscraper located in the London’s Docklands area known as Canary Wharf. With a height of 235 m (770 ft), it is currently (2018) the second tallest building in the United Kingdom. It is predominantly used for offices, although there are a number of retail units on the lower ground floor.
Construction began in 1988, and upon completion in 1991 it was the tallest building in Europe and remained the UK’s tallest building for 20 years, helping to transform the previously derelict Isle of Dogs into a successful financial district.
The developers originally intended to clad the 50-storey tower in stone, but this was later changed to low density aluminium, before settling on stainless steel with a linen finish. It was the first skyscraper to have been constructed with stainless steel. In total, approximately 27,500 tonnes of British steel were used.
The construction involved building a large cofferdam to prevent water leakage into the site, and 222 piles were driven into the ground to depths of 23 m. A 4 m-thick concrete raft was sunk into the ground to act as an anchor.
The stainless steel pyramidal roof, measuring 30 sq. m at its base, encloses maintenance plant and other facilities for water supply, as well as a warning beacon for aircraft travelling to and from the nearby London City Airport.
