Homeowners looking to buy an HDB flat in Singapore face a variety of flat types to choose from. Often, the choice depends on the buyer’s needs – a single person or a young couple with no children may consider a 2- or 3-room flat, since these have 1 or 2 bedrooms, respectively. Meanwhile, an extended family might consider an Executive flat, or even a 3Gen flat, due to the larger space these units offer. But for most Singaporeans, the choice often lies between a 4- or 5-room flat, and it is frequently price that determines which you choose. 5-room flats, being larger, are more expensive than 4-room flats.

4- and 5-room HDB flats in Singapore typically have similar floor plans. Both have a master bedroom with an attached bathroom, 2 smaller bedrooms, a common bathroom, and a kitchen. The main difference between the two is that the 5-room flat has a larger kitchen and a larger living and dining room, with layouts from HDB that include a suggested study area, whereas the 4-room flat doesn’t have space for one.

What Is The Price Difference Between 4-Room And 5-Room Flats?
Looking at HDB resale transactions in 2025 alone, the average price of 5-room flats is $781,317, while the average price of 4-room flats is $672,310. This means that in 2025, the average resale price of a 5-room HDB flat is only 16.2% higher than that of a 4-room HDB flat.
The primary contributor to this narrowing price gap is that HDB has been building more 4-room flats than 5-room flats. Homebuyers who prefer newer flats with longer leases would naturally pay a higher premium for these 4-room flats. We can expect this trend to continue in the coming years, since no 5-room flats are being sold under the Prime classification, with 4-room flats the largest option available for these highly sought-after locations.

When breaking it down by HDB town, the main contributors to the narrowing price gap between 4- and 5-room flats are Punggol (11.3%), Sengkang (11.0%), and Sembawang (10.7%). In these relatively newer towns, prices of 4-room flats have appreciated faster than 5-room flats, with homebuyers perhaps willing to pay a premium due to the higher resale demand for 4-room flats.
On the other end of the spectrum, mature estates like Marine Parade (47.7%), Ang Mo Kio (35.3%), and Bukit Timah (35.2%) still demonstrate a significant price gap between 4- and 5-room HDB flats. In many of these HDB towns, the older 5-room flats tend to command a higher premium due to their size.

Which Flat You Choose Depends On Your Needs And Aspirations
Ultimately, the choice of a 4- or 5-room flat will depend mainly on your budget and family size, and secondarily, your investment goals.
5-room flats offer more living area – currently, HDB’s newer 5-room flats are about 110 square metres, compared to 90 square metres for 4-room flats. As HDB describes it, the extra space is “great for larger households of 5 or more members”. From an investment perspective, having a larger living area may also increase the rental income potential.
4-room flats, on the other hand, “are ideal for young couples or parents”, according to HDB, and as the resale prices above show, appear to offer a better return on investment due to the higher demand and lower starting prices.
