At 111 m, St Paul's Cathedral was the tallest building in London from 1710 until it was eventually surpassed by the 118 metre (387 ft) Millbank Tower in 1963. This in turn was overtaken by the BT Tower at 177 m tall in 1964. Throughout the 1960s and 1970s several high-rise buildings were built, mostly in the western side of Central London and the City of London. In 1980, the 183 metre (600 ft) NatWest Tower (now Tower 42) was completed in the City of London. In 1991, One Canada Square was topped-out at 235 m, becoming the centrepiece of the Canary Wharf development. The 2000s saw the beginnings of a boom in skyscraper building, mostly in the City of London and Canary Wharf. Since 2012, the tallest building in London has been The Shard at London Bridge, which was topped out at 309.6 m. 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. As of 2022, there are 121 buildings or structures that are at least 100 m tall in the Greater London metropolitan area, with 24 of these being in the City of London and 27 being in the Canary Wharf / Isle of Dogs district. The Greater London metropolitan area contains the second most skyscrapers of any city in Europe after Moscow. There are 42 skyscrapers in Greater London that reach a roof height of at least 150 m.

History

Medieval and early modern period

The history of tall structures in London began with the completion of the 27 m White Tower, a part of the Tower of London, in 1098. The first structure to surpass a height of 100 m was the Old St Paul's Cathedral. Completed in 1310, it stood at a height of 150 m. St Paul's was the world's tallest structure until 1311, when its height was surpassed by Lincoln Cathedral in Lincoln. It regained the title when the spire of Lincoln Cathedral fell in 1549. Although the spire of the Old St Paul's was destroyed by lightning in 1561, it still stood as the tallest structure in London, while the world's tallest structure became Strasbourg Cathedral in Strasbourg, France. St Paul's was severely damaged by the Great Fire of London in 1666. The title of the tallest structure in London passed to Southwark Cathedral, which stands at a height of 50 m and no structure in London again rose above 100 metres until 1710, when the current St Paul's Cathedral was completed at 111 m, becoming London's tallest building.

19th century

Few skyscrapers were built in London before the late 20th century, owing to restrictions on building heights originally imposed by the London Building Act of 1894, which followed the construction of the 14-storey Queen Anne's Mansions. 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.

1960s and 1970s

The lifting of height restrictions caused a boom in the construction of tall buildings during the 1960s. St Paul's Cathedral remained as London's tallest building until it was overtaken in 1963 by the Millbank Tower at 118 m, which in turn was overtaken by the BT Tower which topped out just one year later in 1964 at 177 m and officially opened in 1965 (then known as the Post Office Tower). One of London's first notable tall buildings was the 117 m Centre Point, completed in 1966. Others completed in the 1960s include: the Empress State Building at 100 m in 1961, the Shell Centre at 107 m in 1961, the London Hilton at 101 m in 1963, Portland House at 101 m in 1963, and Euston Tower at 124 m in 1970, all built on the west side of Central London. In 1969, St. Helen's at 118 m was completed in the City of London, along with Britannic House in 1967 at 122 metres (400 ft), but the latter was refurbished in 2000, increased to 127m in height and renamed Citypoint. Cromwell Tower, completed in 1973, Lauderdale Tower, completed in 1974 and Shakespeare Tower, completed in 1976, all at 123 m, were built as part of the Barbican Estate in the northern part of the City of London.

1980s, 1990s and 2000s

The NatWest Tower, later renamed Tower 42, was completed in 1980, which at 183 m and 42 storeys, was considered the first "skyscraper" in the City of London. Its height was controversial, being contrary to the previous height restrictions, it was the tallest building in the United Kingdom at the time and also the tallest cantilever building in the world. Following an over ten-year gap, One Canada Square was completed in 1991 at 235 m and formed the centrepiece of the Canary Wharf development, which itself is part of the Isle of Dogs and can be considered the east-side of Central London. At 50 storeys, it became the tallest building in the United Kingdom. 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. Following another over 10-year gap, 8 Canada Square and 25 Canada Square, both standing at 200 m, were completed at Canary Wharf in 2002. Several others of a smaller height followed at Canary Wharf including: Heron Quays, 40 Bank Street in 2003 at 153 m, 10 Upper Bank Street in 2003 at 151 m, and 25 Bank Street in 2004 at 153 m. In the City of London, The Gherkin was completed in 2003 at 180 m, Heron Tower in 2007 at 230 m, and the Broadgate Tower in 2008 at 165 m. Notably, some of the awards given to 30 St Mary Axe include the Emporis Skyscraper Award in 2003 and the RIBA Stirling Prize for Architecture in 2004.

2010s to present

Boris Johnson, who was Mayor of London from 2008 to 2016, approved the construction of more skyscrapers in London. At the time of its completion in 2010, Strata SE1 was the tallest residential building in London. The Shard topped out in 2012 at London Bridge and at 309.6 m remains London's tallest building. In 2014, the 225 m tall 122 Leadenhall Street, nicknamed "the Cheesegrater", was completed in the City of London. In September 2016, a refit was completed of the 111m King's Reach Tower, originally built in the 1970s, which included an 11-storey height increase to bring it up to 150 m tall and it was renamed the South Bank Tower. One Blackfriars, also located on the South Bank, topped out in 2017 at 163 m. The Scalpel, at 190 m was completed in the City of London in 2018 and it was designed to protect views of St Paul's Cathedral. Newfoundland Quay, at 220 m and Landmark Pinnacle at 233 m topped out in Canary Wharf in 2018 and 2019 respectively. One Park Drive at 205 m and South Quay Plaza at 215 m both also topped out at Canary Wharf in 2019. 22 Bishopsgate, at 278 m topped out in the City of London in 2019, after being approved by the current mayor of London, Sadiq Khan, in 2016. 1 Undershaft, at 290 m, also approved by Sadiq Khan in 2016, is planned to form the centrepiece of the City of London's skyscraper cluster. It is the tallest skyscraper currently proposed for London and will only be exceeded in height by The Shard. It will be built on the site of the aforementioned 1969 St Helen's building which will be demolished. 100 Leadenhall, at 249 m, and already nicknamed the "Cheesegrater 2", is also planned for the City of London. Spire London, at 235 m is planned for Canary Wharf. However, construction was halted after concerns that the building only had one escape stairwell for residents on the upper floors. The tallest of the two Riverside South towers that have been planned for construction at Canary Wharf since 2008 would have exceeded that cluster's tallest building, One Canada Square, by 1 metre in height, but construction has been stalled since 2011. Construction has started on the 216 m tall Consort Place (previously called Alpha Square) also at Canary Wharf. There is another major skyscraper cluster emerging in the Vauxhall and Nine Elms districts of London. The first skyscraper to appear here was St George Wharf Tower at 181 m and which was completed in 2014. The tallest tower planned for this cluster is the 200 m One Nine Elms City Tower. In 2019, Sadiq Khan blocked the construction of the 290 metre tall Tulip that would have been built in the City of London. After an appeal was launched by the developers against Khan's decision, UK housing secretary Michael Gove rejected the proposal in November 2021.
