Comprising 13,150 hectares of land area, it includes 11 planning areas within the Central Area, as well as another 11 more outside it. Although the Central Area is by nature chiefly commercial, especially the area in the Downtown Core, it also includes residential housing units of various types, ranging from HDB flats to more exclusive forms of private housing, such as bungalows, which are a status symbol because land is expensive. There are also 1000 hectares of green spaces, including parks, gardens and other recreational spaces linked by 19 km of park connectors, which were built in order to make this area aesthetically pleasing.
