Based on general information, as the provided context did not contain specific size details, a 3-room HDB flat in Singapore typically has a floor area of around 60 to 65 square meters, which is approximately 645 to 700 square feet. This size is standard for new Build-To-Order (BTO) flats.
It is important to note that the term "3-room" in the context of Singapore's public housing refers to one living room and two bedrooms. The standard layout for such a flat includes a master bedroom with an attached bathroom, a second common bedroom, a common bathroom, a living/dining area, and a kitchen.
The exact size can vary depending on the specific housing project and the era in which the flat was built. Older resale 3-room flats from past decades may sometimes be slightly larger than the newer flats being constructed today.
