help One Canada Square FAQ

How long was One Canada Square the tallest building in the United Kingdom?

The 235-metre Canary Wharf tower held the national height record from its completion in 1991 until The Shard surpassed it during construction in 2010. Its pyramid roof remains one of London's most recognizable skyline features.

Who designed One Canada Square?

Argentine-American architect César Pelli designed the tower for the Canary Wharf development. Its stainless-steel-clad pyramid distinguishes it from the flat-topped office towers nearby.

Can visitors go to an observation deck at One Canada Square?

The building does not have a public observation floor. Most upper levels are commercial offices, so skyline views are generally limited to people visiting tenants or private venues.

Why is One Canada Square associated with the regeneration of Docklands?

It became the visual centerpiece of Canary Wharf as former dockland was redeveloped into a major financial district. The tower opened during the early-1990s recession, when much of the new office complex initially struggled to attract tenants.
