HDB Database is an original compilation “Made by Teoalida” which took over 500 hours of work. Collecting data from multiple sources, I manually entered data in one Excel table for all HDB blocks ever built in Singapore, indicating block number, street address, postal code, GPS coordinates, construction year, lease commence date, number of floors, number of units breakdown by flat type, upgrading programmes, brochures and floor plans.

The database has been purchased by several companies, including home insurance, telecommunication, door-to-door services, real estate portals, flyer distributors, as well as many people who did not told me what business field they are in.
