Use a computer (not phone) for best experience. Open map on full screen. Click each dot on map to view year built, number of floors, number of units, upgrading programmes, typical floor plans, chances to get SERS, etc.

Pink = Blocks built originally without lifts stopping at every floor and kitchen refuse chute, first series (1960-1982).
Red = Blocks built originally without lifts stopping at every floor and kitchen refuse chute, second series (1981-1993).

I compiled HDB block information in Excel format and since 2015 I offered for sale on HDB Database page, being purchased by several real estate agencies as well as telecommunication and home insurance companies. The price is a bit too high for ordinary people who just need to view info about several blocks.
Now you can search here information about desired blocks for FREE! Initially made drop-down boxes in July 2017, then I figured out how to display block information in Google Maps in September 2017. If you like old drop-down boxes, see HDB block search.
Please report possible errors on map! (some blocks may have wrong floor plans, being added from my personal research)
