After the First World War, the population of Wallington increased rapidly and the local Urban District Council outgrew its various offices and so, in 1929, purchased an old house, Sunny Bank, in Woodcote Road and decided to commission a new Town Hall, to be built on Sunny Banks site. The Council became a Borough in 1937, and the Town Hall was the hub of community life up until the incorporation of Beddington and Wallington into the London Borough of Sutton in 1964, and even then, the Council Chamber was used for the new Council's meetings until 1977. Parts of the building continued to be used by other organisations such as the WRVS, the Registrar of Births, Marriages and Deaths, and as a Driving Test Centre. In 1980 it was taken over and converted into a Crown Court. The building ceased to be a Court in April 1999, and has now been converted for educational use.
