the only HDB town to extend across two separate planning areas (i.e. Kallang and Novena). Previously, Kallang was classified as an "estate" but HDB later reorganised the area and promoted it to "new town" status. The first few residential precincts in Kallang, constructed by the HDB, were built in the 1970s and 1980s. Some housing blocks are planned to be reconstructed under the Selective En bloc Redevelopment Scheme (SERS) to redevelop Kallang where the demographics are dominated by the middle-aged. New residential blocks which are around 30-storeys high are now prominent in the skyline of the area, with more being planned to be built under the new HDB construction policy. A notable major redevelopment is underway in the Old Kallang Airport Estate, where many of the low-rise blocks are currently unoccupied. New estates along Bendemeer Road and Upper Boon Keng Road are also popular options. Kallang/Whampoa is the fourth most expensive HDB new town in terms of rental prices. The rental price of a median 4-room HDB unit in Kallang/Whampoa is S$2500, compared to the national average of S$2120. Aside from public housing (flats) built by HDB, condominiums that provide high-end living options can be found primarily in Tanjong Rhu, an affluent neighbourhood in southern Kallang. The precinct is in extreme close proximity to the Central Area located across the Kallang Basin and Marina Channel, as well as Gardens by the Bay (Bay East Garden). Condominium clusters can also be found along Saint Michael's Road and Moonstone Lane, within the subzone of Bendemeer. Car-free residential area will be piloted in the subzone of Kampong Bugis, at the mouth of Kallang River. These new blocks will be part of a fenceless pedestrian-friendly waterfront community that was announced by the government in 2013. Around 4000 new housing units will be ready by 2030. Soil treatment work at the former Kallang Gasworks site began in November 2018 and is expected to conclude in July 2022.
