Oldest HDB in Tampines.

Based on Singapore's public housing history, the oldest HDB estates are those that predate or were among the first completed by the Housing and Development Board after its establishment in 1960.

Tiong Bahru holds the distinction of being Singapore's first-ever public housing estate, though it was originally developed by the Singapore Improvement Trust (SIT) starting in the 1930s. It comprised 784 flats, 54 tenements, and 33 shops, making it a pioneering public housing development.

Queenstown at Stirling Road marks an important transitional point in Singapore's public housing history. Three blocks (numbered 45, 48, and 49) were started under SIT but completed by HDB in 1960, making them the first flats officially built by the HDB.

Toa Payoh was Singapore's first purpose-built new town by HDB, with construction commencing in 1965. Upper Aljunied in Toa Payoh was developed during this early HDB era when concrete slab blocks were the standard construction method.

These early estates were instrumental in HDB's mission to address Singapore's severe housing shortage and overcrowding in the late 1950s and early 1960s. Today, Tiong Bahru in particular remains one of the few surviving examples of pre-1960s public housing, offering a unique glimpse into Singapore's housing evolution.
