Punggol is a famous place for water sports while in Hougang, you may lend a hand to various charity organizations in the area. In Sengkang, there are a few shopping malls where you can get your daily amenities. District 19 is in the north-eastern part of Singapore and is made up of these three areas. All three areas are residential areas with recreational and commercial activities.
Hougang
Hougang comprises seven sub-zones: Hougang, Trafalgar, Rosyth, Lorong Ah Soo, Tai Keng, Defu Industrial Park and Sungei Serangoon. The name "Hougang" is the literal Hanyu Pinyin for 'Ow Kang', which means "back of the river" in Hokkien, a Chinese dialect. Formerly, Hougang was a village populated by Chinese Teochew or Hokkien immigrants. The British sealed off a place known as Trafalgar in Hougang in 1928. Now known as Buangkok, it houses the hospital being used for chronically and mentally ill patients. The hospital was named Woodbridge after a small wooden bridge beside the site. It has since been rebuilt and renamed the Institute of Mental Health (IMH). There are many HDB flats in the main Hougang area, as well as HUDC flats, condominiums and private houses in Lorong Ah Soo and Rosyth. Kampong Buangkok is the last village in Singapore. One of the distinguishing old-fashioned features of Kampong Buangkok is that it uses generators for electricity instead of power plants.
Punggol
The Urban Redevelopment Authority plans to develop Punggol into the Punggol New Town, under a scheme called "Punggol 21". Like many areas in Singapore named after Malay words, Punggol's name comes from the Malay word "punggul", which stands for the action of throwing sticks at the branches of fruit trees to loosen the fruit from the stem. The word also refers to a fruit and forest produce wholesale place. Prior to the 1970s, Punggol was a place of rubber planting, poultry farming and pig rearing. Today, it is a new waterfront estate, with HDB flats, condominiums and private housing.
Sengkang
Sengkang Planning Area covers the Housing and Development Board satellite town of Sengkang New Town and rural Jalan Kayu. Sengkang stands for "prosperous harbour" in Chinese. Formerly known as Kangkar, or "foot of the port" in Hokkien, there was once a fishing port along Sungei Serangoon. Vegetable and pig farms could also be found in the area before the Sengkang New Town was built. The old Punggol Rural Centre was also demolished in 2005 to make way for new high-rise apartment blocks. Today, Sengkang is a sub-urban residential area with smaller HDB houses than other areas. Residents of the houses along Sungei Serangoon and Sungei Punggol will enjoy the stunning view and the water sports in the waterfront
