One Canada Square (also known as the Canary Wharf Tower) is a skyscraper in Canary Wharf, London. 
It's the tallest building in the United Kingdom has 50 storeys, and stands at 244 metres (800 ft) above sea level.
Original developers Olympia & York and architects Cesar Pelli & Associates, Adamson Associates, and Frederick Gibberd Coombes & Partners finalised the design in 1988 and then construction began. In May 1992 Olympia & York went into bankruptcy administration and ownership of the tower has changed several times since. After this inauspicious start the area has succeeded in drawing a considerable number of businesses from the City to relocate to the Isle of Dogs (where Canary Warf and the 'Docklands' are situated.
The Canary Wharf towers have caused television reception interference for local people living in the area, as in the case Patricia Hunter and others v. 
Canary Wharf Ltd.[1997], where the House of Lords concluded there is no legal right to receive good television reception.
The top of the building periodically releases plumes of condensation from its air conditioning system which was often mistaken for smoke, in the years after it opened. Planes arriving at the nearby City airport have to negotiate the ever growing number of towers which have arisen in the surrounding area.
