of the parish was still only 109, but during that decade residential and commercial development started apace and continued after World War II. Housing spread northwestwards from Hove and Aldrington, especially from 1936 onwards, and the whole area was built over by the end of the 1950s. St Helen's Church, which was "still entirely isolated" in 1929 when it was kept locked except during services, became surrounded by houses; it was reopened for regular worship in 1949, having been used irregularly (sometimes as infrequently as once per year) since the mid-19th century. Housebuilding in the parish was largely complete by the end of the 1950s, although the population has continued to grow: at the 1951 census it was 6,158, rising to 9,006 in 1961 and an estimated 14,270 in 2013. Hangleton is popular both with families and with retired people, and the percentage of residents under the age of 16 is one of the highest of any ward in the city of Brighton and Hove. The earliest housing was provided by Hove Borough Council and was mostly terraced or semi-detached. Also in the 1930s, but mostly in the 1950s, private developments of semi-detached houses and detached bungalows emerged, especially on the highest ground offering good views of the South Downs and the sea. There are also some low-rise blocks of flats. Many streets are lined with trees and extensive grass verges, some houses have large front gardens, and the overall housing density is low—especially in the northwest of the estate, where most of the privately developed bungalows are situated. The council housing is mostly in the north and east of the estate. Most houses built by the council are now owned by their occupiers; privately rented housing is the other main form of housing tenure. In 1951 the parish had a population of 2676. On 1 April 1974 the parish was abolished. Hangleton Manor became a farmhouse and was still used as such until 1930 when the farm was broken up and the land allocated for residential development. The 16th-century building went through various uses—a private house, a hotel and a restaurant—and was requisitioned by the Army in World War II. It became a listed building in 1956, but it was in such poor condition that demolition was anticipated. Between 1964 and 1967 it was empty and suffered repeated vandalism, but in the latter year a plan to convert the
