The first flats in the new town were completed in 1975, and construction work on the initial section of the town centre, and on the new town's area office, was underway by September 1976. The town centre was planned to comprise a pedestrian mall, which encompassed most of the town centre, a hawker centre, an open area and a bus terminal, and to cater to residents of the new town along with the adjacent Mayflower and Serangoon Gardens estates. In April 1978, the Housing and Development Board introduced a new numbering system for blocks and streets, in which the numbers of the blocks and streets correspond to the neighbourhood that they are located in, in Ang Mo Kio, and subsequently for new towns developed thereafter.
