The HDB announced on Sunday that it would be launching 6,900 BTO units in its June BTO exercise, of which around 2,520 have a waiting time of less than 3 years.
Everywhere we look, it appears that the HDB is building more and more BTOs and one will inevitably wonder - how many flats is the HDB building at any one time and how many flats get completed since the pace seems to have picked up tremendously since COVID.
Well, thankfully we have statistics that can enlighten us and the numbers are... not really that shocking.
In 2025, the HDB completed 19,600 flats including the final ones that were delayed by the COVID-19 pandemic like Punggol Point Cove.
In 2024, the number was 20,294 and in 2023 it was 18,450. As expected, the lowest number of HDB flats completed in recent years was 2020, a year we would all rather forget where only 8,234 flats were completed.
So it appears that the HDB is working around a rough figure of 20k flats being completed every year moving forward and this seems like a sizable number especially with the seemingly large number of HDB construction sites all over the island.
And while we are certainly building a lot more flats than we did twenty years ago when the HDB building programme ground to a halt due to oversupply in the late 1990s, we are actually NO WHERE near the peak production of HDB flats. For that, we have to look to the 1980s.
In late 1979 early 1980, the HDB embarked on its fifth five-year building programme where it said it was aiming to complete 85,000 - 100,000 flats from 1981 to 1985. It also said (in the HDB’s 1979/80 Annual Report) that it would have completed 127,600 flats in the preceding five-year building programme (1976-1980).
By the end of 1985, the HDB managed to DOUBLE the number of flats it was initially aiming for the 1980-1985 period, delivering a whopping 185,266 flats.
In 1984 alone, the HDB built 73,231 flats. That number is nearly four times the number of flats completed in 2025.
In Tampines, 10,064 flats were completed in 1984.
In Bukit Batok, 11,963 flats were completed in 1984.
And in Yishun, a mind-boggling 12,617 flats were completed in 1984.
The HDB may still be Singapore’s largest developer, but it isn’t building even a quarter of what it was at its peak.
This image is a new one I just made this evening for my Unfinished Business project and it shows the cranes operating at the HDB Urban Rise BTO project next to Causeway Point which will yield 848 flats when it is completed in 2028.
