ONE Croydon (or the 50p Building, formerly the NLA Tower, the Weddingcake or Threepenny bit building) is a skyscraper at 12–16 Addiscombe Road, Croydon, London, next to East Croydon station. It was designed by Richard Seifert & Partners and completed in 1970. It has 24 storeys and is 269 feet (82 m) high. 'NLA' stood for 'Noble Lowndes Annuities'. The growing town of Croydon attracted many new buildings to be built in the 1960s including ONE Croydon. In recent years, the development of tall buildings has been encouraged in the London Plan, which will lead to the erection of new skyscrapers over the next few years as London goes through a high-rise boom.
