Jurong West is a planning area and residential town located in the West Region of Singapore. Jurong West shares boundaries with Tengah in the north, Jurong East in the east, Boon Lay and Pioneer in the south, and Western Water Catchment in the west. Originally a forested area, Jurong West is undergoing rapid development under the ambition of the Housing and Development Board (HDB) to transform it into a fully mature housing estate. History Jurong West originated from the area once called Peng Kang, named after the gambier plantations along Sungei Jurong. By the mid-20th century, the area was home to several brickworks, palm oil plantations and nurseries. At that time, the only public housing estates in Jurong West were Boon Lay and Taman Jurong. Jurong West was largely left alone until 1984, when the HDB began conceptualisation for a new town in Jurong West. Jurong West was carved into nine subzones that would house a total of 94,000 public and private housing units in the long term. The town's first apartment blocks (known locally as flats) were completed at Taman Jurong in 1963. By November 2004, about 71,522 dwelling units were completed. As of 31 March 2018, there are 74,301 HDB dwelling units in Jurong West.
