How many 3-room HDB flats have been built in Singapore

As of the latest publicly available figures, there are approximately 251,000 HDB 3-room flats in Singapore. This refers to 3-room HDB units currently under management and does not include those that have been demolished or adjoined over the decades since HDB’s founding.

3-room flats have been a standard flat type in public housing since the early years of HDB development. Their total built number has changed over time due to redevelopment and upgrading projects, but the current stock hovers around this figure according to the most recent annual statistics published by public sources.
