Planning Areas and Subzones in Singapore
A subzone is an official administrative division within a planning area, created by the Urban Redevelopment Authority (URA) to support urban management, statistical reporting, and land-use planning. This system was formally introduced in the early 1990s1 and remains an important part of Singapore’s urban governance.
Currently, Singapore is divided into 323 subzones across 55 planning areas2. While subzones such as Peng Siang help urban planners with detailed demographic and developmental insights, residents typically refer to their home area by the broader planning area or town name, such as “Choa Chu Kang.”

Peng Siang is predominantly residential, characterised by HDB housing blocks, neighbourhood shops, and educational institutions. The subzone is integrated into the wider Choa Chu Kang town centre, ensuring residents have easy access to public transport, retail, and community facilities.
- HDB estates – forming the backbone of the subzone’s housing stock.
- Neighbourhood shops – providing groceries, dining, and essential services.
- Schools – offering convenient education options for families.
