A regional centre in the city-state of Singapore is a second-tier commercial zone after the main central business district in the Central Area. About 15 times the size of a normal town center in Housing Development Board (HDB) towns, they are located in three suburban districts of Singapore, namely the Woodlands Regional Centre located at Woodlands in the North Region; the Tampines Regional Centre at Tampines in the East Region, and the Jurong East Regional Centre at Jurong East in the West Region. Original plans for these regional centres included a fourth regional centre serving the North-East Region in Seletar, but it has since been dropped.
