office to a town sub-post office on 20 August 1916. It continues to operate but with very limited services. Hospital West Heath Hospital was established as an infectious diseases hospital in 1889, became a tuberculosis hospital in 1910 and was refocused as a geriatric hospital in 1980. Expansion In 1900 visitors arriving via Northfield railway station could visit the skating rink on West Heath Road next to the bridge over the river Rea. Unfortunately the skating rink was used during the First World War as a munitions factory and following an accident the rink was destroyed by fire. In the 1930s small terraced houses that were built along Alvechurch Road and Sir Hilton's Road, and slightly grander semi-detached and detached houses, along West Heath Road and Redditch Road began to change the traditional rural nature of West Heath. The newer high density housing estates built two decades later would complete the change. The rapid expansion of West Heath and its transition from open farm land to residential suburb of Birmingham had commenced in the years immediately after the Second World War when several extensive estates of pre-fab houses were quickly erected to house returning servicemen and families made homeless during wartime bombing raids. Another notable building of the area was The Bath Tub open air lido (now demolished), opened on 1 July 1937 in Alvechurch Road, where 20,000 people had gathered to watch the opening ceremony by Gracie Fields with Mantovani and his orchestra and the M.P. for Northfield and Kings Norton, Ronald Cartland, the brother of Dame Barbara Cartland, the novelist. The lido which had been built by Percy Hollier who intended it to be "Birmingham's brightest entertainment spot" and which included a 180 feet by 90 feet sized swimming pool as well as a putting green, lawn for archery and a children's playground, only operated for 3 years and was closed due to commercial failure. Laughtons took over the site with Eddystone Radio during the war when its rural location helped it to avoid attack by German air raids. The lido site is now covered by a housing estate. There is also the art deco Man On The Moon pub on Redditch Road, which was built in 1937 (originally as The Man In The Moon but the name was changed in 1969 to commemorate the first moon landing).
