No. 1 Croydon (formerly the NLA Tower, and colloquially the 50p Building, the Weddingcake or the 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'. It was one of many new buildings constructed in the growing town of Croydon in the 1960s. The development of tall buildings was later encouraged in the 2004 London Plan, which led to the erection of new skyscrapers as London went through a high-rise boom.
