By the 1980s, the Housing Development Board (HDB) had already begun further expanding the area into a satellite housing estate to meet the rising demand for housing from Singapore's then-growing population. The residents in Kampong San Teng were resettled and a mass exhumation of the 170,000 graves were carried out in 1980. Redevelopment of the area officially started in 1982. On this land, HDB planned to construct 24,600 residential units distributed across 4 distinct neighbourhoods: Bishan East, Bishan North, Bishan West (subsequently renamed Sin Ming Garden Estate in 1988) and Shunfu Estate, of which Bishan East will be the largest.
