4-room HDB flats are especially popular in Singapore because they offer an ideal balance of space, affordability, and versatility for most households. These units, typically around 90 square meters, come with three bedrooms and two bathrooms, offering ample room for families of four to five members—an average household size in Singapore. The layout accommodates essential privacy, personal space, and flexibility for additional uses, like a study or guest room.
Compared to 5-room flats, 4-room units are generally more affordable, appealing to first-time buyers and young families who want enough living space without overextending financially. The government also prioritizes offering four-room flats in new Build-to-Order (BTO) projects due to this high demand, which has led to higher availability of these units across HDB developments.
Furthermore, 4-room flats often offer a higher potential resale value, making them attractive for investment-conscious buyers.
