45, 48 and 49 Stirling Road are three residential flats on Stirling Road in Queenstown, Singapore. They were the first three public housing blocks completed by the Housing and Development Board (HDB) in 1960, having been previously left unfinished by its predecessor, the Singapore Improvement Trust (SIT). While historically significant, these flats were not the first public housing blocks constructed in Singapore, as SIT flats were already constructed decades prior at Tiong Bahru during the 1930s.
