Sengkang (, ) is a planning area and residential town located in the North-East Region of Singapore. The town is the second most populous in the region, being home to 249,370 residents in 2020. Sengkang shares boundaries with Seletar and Punggol in the north, Pasir Ris and Paya Lebar in the east, Hougang and Serangoon to the south, as well as Yishun and Ang Mo Kio to the west. Originally a fishing village, the area underwent rapid development under the ambition of the Housing and Development Board (HDB) to transform it into a fully mature housing estate. Etymology The name Sengkang means "prosperous harbour" in Chinese, and “to chock, block or wedge” in Malay. The name was derived from Lorong Sengkang, a former Malay kampong road, off Lorong Buangkok. Lorongs were common in the area before urban redevelopment. The area was formerly known as Kangkar (Gang Jiao 港脚) or "foot of the port" as there was once a fishing port located along Sungei Serangoon. History Sengkang originated from the area once called Kangkar, named after the port and fishing village along Sungei Serangoon. By the mid-20th century, the area was home to several rubber, pepper, and pineapple plantations. At that time, the nearest public housing estate then was the Punggol Rural Centre located along Punggol Road. Sengkang was largely left alone until 1994, when an urban design team of ten from HDB began conceptualization for a new town in Sengkang. Sengkang was carved up into seven subzones that would house a total of 95,000 public and private housing units in the long term. Conjured by local newspapers, Sengkang's theme became 'Town of the Seafarer', which reflects its history as a fishing village. Two sub-themes were assigned to the four neighbourhood areas (namely Rivervale, Compassvale, Anchorvale, and Fernvale) of the new town: one reflected Sengkang's marine history, while the other related to the sprawling plantations that previously covered parts of the area. The neighborhoods were each given a name and a colour scheme to go with their respective themes. The three-storey pilotis or stilt effect was also utilized in the design of housing blocks, to resemble the stilts of fishing villages and trunks of the various plantations of bygone years. The town's first apartment blocks (known locally as flats) at Rivervale were completed in 1997. By August 2001, about 33,700 dwelling units were completed. As of 31 March 2017, there are
