Singapore · Public Housing
This archive documents the block number markings found on Singapore's public housing blocks — the large-format numerals that identify each HDB building across the island. These numbers, often rendered in bold painted or metal letterforms, form a distinctive visual language of Singapore's urban landscape.
The Housing and Development Board (HDB) was established in 1960 to address Singapore's acute housing shortage. Today, over 80% of Singapore's resident population lives in HDB flats across 26 towns and 3 estates. Each block is assigned a unique number within its town, creating a systematic addressing system that spans the entire island.
Block numbers in Singapore range from single digits to four-digit numbers, often with alphabetical suffixes (e.g. 506B, 658D). The visual treatment of these numbers varies significantly across estates and eras — from painted concrete to cast metal plaques, from minimalist sans-serif to ornate letterforms — reflecting the architectural history of each neighbourhood.
