How Many HDB Blocks Are There by Each Town in Singapore?

By /

Singapore’s public housing system is one of the most successful urban housing models in the world. Developed and managed by the Housing & Development Board, commonly known as HDB, these residential estates house more than 80% of Singapore’s resident population.

One common question people ask is:

How many HDB blocks are there in each town in Singapore?

While the exact number changes regularly due to new developments, redevelopment projects, demolitions, and Build-To-Order (BTO) launches, Singapore currently has more than 10,000 HDB residential blocks spread across the island.

These blocks are distributed across major HDB towns and estates, each with its own size, population density, and urban planning characteristics.

This article explores:

  • Estimated HDB block counts by town
  • The largest HDB towns in Singapore
  • Mature vs non-mature estates

  • Central locations

Many older HDB blocks in these towns were built during Singapore’s earlier housing development phases.

Non-Mature Estates

Newer towns include:

  • Punggol
  • Sengkang
  • Tengah

Characteristics:

  • Newer architecture
  • Smart town features
  • Larger integrated developments
  • Modern facilities

These towns are still growing rapidly and adding new HDB blocks regularly.

HDB Block Density by Region

North Region

Major towns:

  • Woodlands
  • Yishun
  • Sembawang

The north region contains a large concentration of public housing due to available land and regional development planning.

East Region

Major towns:

  • Bedok
  • Tampines
  • Pasir Ris

Eastern Singapore has some of the highest HDB populations in the country.

West Region

Major towns:

  • Jurong West
