List of tallest buildings and structures in London

In 1991, One Canada Square was topped-out at 235 metres (771 ft), becoming the centrepiece of the Canary Wharf development.

There are several tall buildings planned for the City and Canary Wharf, with further clusters emerging in other districts of London including: Stratford, the South Bank, Elephant and Castle, Vauxhall, Nine Elms, Islington, Lewisham as well as in places in Outer London such as Croydon.

[11] Though restrictions have long since been eased, harsh regulations remain to preserve protected views, especially those of St Paul's, the Tower of London and Palace of Westminster, as well as to comply with the requirements of the Civil Aviation Authority.

[35] Following an over ten-year gap, One Canada Square was completed in 1991 at 235 metres (771 ft) and formed the centrepiece of the Canary Wharf development,[35] which itself is part of the Isle of Dogs and can be considered the east-side of Central London.

[35] With the encouragement of Ken Livingstone who was Mayor of London from 2000 to 2008, a renewed trend for building tall was established in the 2000s.

[51] In 2014, the 225 metres (738 ft) tall 122 Leadenhall Street, nicknamed "the Cheesegrater", was completed in the City of London.

[54][55] The Scalpel, at 190 metres (620 ft) was completed in the City of London in 2018 and it was designed to protect views of St Paul's Cathedral.

[2] 1 Undershaft, at 290 metres (950 ft), also approved by Sadiq Khan in 2016,[2] is planned to form the centrepiece of the City of London's skyscraper cluster.

[66] However, construction was halted after concerns that the building only had one escape stairwell for residents on the upper floors.

[67][68] Construction has started on the 216 metres (709 ft) tall Consort Place (previously called Alpha Square) also at Canary Wharf.

[70][71] The first skyscraper to appear here was St George Wharf Tower at 181 metres (594 ft) and which was completed in 2014.

[73] In 2019, Sadiq Khan blocked the construction of the 290 metre tall Tulip that would have been built in the City of London.

[74] After an appeal was launched by the developers against Khan's decision, UK housing secretary Michael Gove rejected the proposal in November 2021.

[75][76] This list ranks externally complete London skyscrapers and free-standing towers that stand at least 100 m (327 ft) tall, based on standard height measurement.
