List of tallest buildings and structures in the London Borough of Croydon

This list of the tallest buildings and structures in Croydon ranks buildings and structures in the London Borough of Croydon, England by height. The borough of Croydon, a local government district of Greater London, has a population of 330,587. At its core is Croydon, a former market town, with interests in producing charcoal, tanned leather, and brewing.

History
In contrast to the vast majority of London's tallest buildings, most of Croydon's high-rises were constructed in the 1960s and 70s as part of a project to create the South of England's largest office space outside of Central London. However, since then many of these office blocks have become outdated and some of the early high-rise buildings have subsequently been demolished, to allow for new skyscrapers to be constructed in their place. More recently, a new redevelopment programme for the town centre, called Croydon Vision 2020 was announced. The town has since witnessed a boom in the construction of high rise apartments, such as IYLO and Altitude 25, a former brownfield site.

For 38 years, the tallest building in Croydon was the No. 1 Croydon (formerly the NLA Tower), a high-rise office block, which was completed in 1970, until 2009, when Altitude 25, a residential high-rise complex, was completed. Saffron Square became the tallest building in Croydon in 2016 at 134 metres tall, but was overtaken by 101 George Street, the current tallest building in Croydon in 2019. The current tallest building is College Road which topped out in 2022 at 149 metres, and is also the Europe's tallest modular building.

In December 2022, Croydon Council (Conservative run) was warned by Councillor Patricia Hay-Justice (Labour), in a meeting of Council officers and planning officials that Croydon is not Manhattan and that the suburb should not resemble New York City in a row over a new skyscraper development.

Timeline of tallest buildings and structures

This was replaced in 2016 by Saffron Square, a 2016 Carbuncle Cup-nominated high-rise completed as part of Croydon Vision 2020. Other high-rise buildings proposed to be built under the programme include the taller Morello Tower (171m) and One Landsdowne Road (228m).
