Do smaller condo units still sell at higher psf? We checked.
By Realila
For decades the answer was yes: smaller units sold at higher per-square-foot prices than larger units in the same building. Between 2021 and 2025, that premium collapsed and tipped negative. Here is the evidence. The rest of what we found about shoebox units in Singapore is on the shoebox units guide.
Analysis date: 1 August 2026. Data through 19 July 2026 (private caveats) and 1 July 2026 (HDB resale). Updated 4 August 2026, see the note at the foot.
Ask anyone in Singapore property and you will hear the same rule: smaller units carry higher psf, larger units carry lower psf. Agents price with it. Buyers use it to judge whether a listing is expensive or cheap. Developers built their price lists around it. It is probably the most repeated rule of thumb in this market.
It was true for a long time. It is not true anymore.
Inside the very same condo developments, the price-per-square-foot premium that shoebox units commanded over family-sized units has fallen from around 21% to below zero. In the most recent readings the family-sized units in the same building transact at higher psf than the shoeboxes.
Nobody announced this. The market's most familiar pricing rule quietly died, and pricing habits have not caught up.
Key takeaways
- The shoebox psf premium inside the same development fell from +20.9% in 2017 to −3.1% in 2025, crossing zero for the first time. How we measured it
- Not a composition effect: across 49 developments transacting in both windows, the premium compressed in 43. The paired test
- Not a floor effect: holding the five-storey band constant, it compressed in 33 of 35 cells. The floor test
- Not a shift in taste for space: HDB moved the opposite way over the same years, with no investors in that market. The HDB control
- Developers priced it out too: their own launch premium went from +11.0% in 2016 to −5.3% in part-2026. Launch pricing
What we mean by shoebox
We use URA's threshold: a shoebox is a unit of 50 square metres or less, which is 538 sqft. Every figure below compares units of 400–538 sqft against family-sized units of 1,000–1,500 sqft, in the same development.
The rule, and why it existed
Three standard explanations have always been offered for the size-psf slope. First, affordability: far more buyers can pay S$800,000 than S$2.4 million, so the cheapest ticket into a location gets bid up per square foot. Second, construction: kitchens, bathrooms and building services cost roughly the same whether the unit is 450 sqft or 1,400 sqft, and spreading those fixed costs over fewer square feet raises the psf. Third, investors: shoebox units rent out at better per-square-foot yields and are easier to exit, so investors concentrated in them and paid up for the privilege.
Keep the third one in mind. It matters later.
What the data shows, inside the same buildings
Market-wide averages are a poor test of this rule, because they compare different buildings in different locations of different ages. The rule as people actually use it is a within-building rule: in this development, the 1-bedder trades at a higher psf than the 4-bedder. So that is where we measured it.
For every condo development, in every year, we compared the median resale psf of shoebox units against family-sized units in that same development, wherever both had at least three transactions. The table shows the median premium across all qualifying developments.
| Year | Shoebox psf premium (same development, resale) | Developments measured |
|---|---|---|
| 2017 | +20.9% | 24 |
| 2018 | +18.0% | 28 |
| 2019 | +14.9% | 16 |
| 2020 | +10.1% | 35 |
| 2021 | +10.8% | 69 |
| 2022 | +5.3% | 65 |
| 2023 | +4.7% | 59 |
| 2024 | +0.6% | 60 |
| 2025 | −3.1% | 70 |
| 2026 (to 19 Jul) | −11.5% | 24 |
The premium fell in seven of the nine year-on-year steps, from around 21% to zero, and crossed into negative territory in 2025.
Maybe different buildings are just selling now?
A fair objection: the set of developments with enough transactions changes over time. So we ran a stricter test. We took only the developments that had both shoebox and family-sized units transacting in both periods, 2017–2019 and 2023–2025, and compared each development with itself.
Forty-nine developments qualified. Their median shoebox premium fell from +17.2% to +4.3%. The premium compressed in 43 of the 49.
Same building. Same location. Same tenure. Aged equally. The premium still collapsed.
Maybe it's a floor effect?
Larger units sometimes sit on higher floors, and higher floors carry higher psf. Could a shift in which floors were transacting explain it?
No. In the strictest version of the test, comparing shoebox against family-sized units within the same development and the same five-storey floor band in both periods, the premium fell from +18.9% to +4.2%, compressing in 33 of the 35 measurable cells.
Matching on development, floor band and both time windows at once is expensive: it leaves thirty-five cells. But floors cannot explain a fall that survives holding the floor band constant.
Maybe Singaporeans just want bigger homes now?
The popular story since the pandemic: work-from-home made everyone value space, so bigger units re-rated. If that were the cause, it should show up wherever Singaporeans buy homes to live in.
Singapore happens to run a near-perfect test for this. The HDB resale market is the one housing market with essentially no investors: you must live in the flat, a five-year minimum occupation period applies, and a family can own only one. Same population, same years, same pandemic, but investor demand switched off.
If space preference re-rated big homes, HDB 5-room flats should have gained on 3-room flats after 2020. They did the opposite:
| Year | HDB 5-room psf vs 3-room psf (resale, median) |
|---|---|
| 2014 | −12.0% |
| 2017 | −8.4% |
| 2020 | −0.3% |
| 2022 | −2.9% |
| 2024 | −3.8% |
| 2026 (to 1 Jul) | −2.6% |
HDB's size gap converged for its own reasons up to 2020, then drifted slightly apart again. The private market's within-building premium moved more than twenty points in the opposite direction over the same years. A population-wide taste for space cannot produce opposite movements in the two markets. That explanation fails. (For the broader HDB picture this quarter, see our HDB resale brief for Q2 2026.)
Maybe developers stopped building small units?
They did build fewer, and by regulation. URA first capped unit counts in 2012 precisely to moderate what it described as excessive development of shoebox units. In October 2018 it tightened the cap: outside the Central Area, the maximum number of units became the building's gross floor area divided by 85 sqm, up from 70 sqm, with a stricter 100 sqm divisor in nine areas under infrastructure strain, effective for development applications from 17 January 2019 (URA circular URA/PB/2018/06-DCG). The October 2022 revision went further: under the guidelines applying to applications from 18 January 2023, developments outside the Central Area must keep units of 50 sqm or less to at most 20% of the project, and provide at least 20% of units at 100 sqm or larger (URA circular URA/PB/2022/10-CUDG).
But notice what restricting the new supply of shoebox units should do to existing shoebox units: make them scarcer, and therefore relatively more expensive. The premium should have risen.
It fell. Wrong direction. That explanation fails too.
The explanation left standing
Strip away composition, floors, space preference and supply, and one candidate remains: the buyers who paid the premium stopped showing up.
Shoebox units were the investor product. Lower entry price, better rental psf, easier resale. Then the maths broke, in two blows. From 16 December 2021, ABSD for a Singapore Citizen's second residential property rose from 12% to 17%, and for foreign buyers from 20% to 30%, while the Total Debt Servicing Ratio threshold tightened from 60% to 55% (MOF/MND/MAS joint announcement, 15 December 2021). From 27 April 2023, the second-property rate for Citizens rose again to 20%, and the foreign-buyer rate doubled to 60%. Interest rates also climbed steeply through 2022 and 2023. We originally wrote that this crushed the yield spread that made small units work as an income play. That was wrong. See the correction note at the foot of this article. Rents held their premium, so shoebox yields rose rather than fell.
The shape of the collapse fits this mechanism precisely. It is not a one-year shock. It is a steady bleed across most of a decade, exactly what cumulative policy pressure produces as holding periods roll over and marginal buyers exit one by one.
One honesty note: caveat records do not identify who the buyer is, so this is an inference by elimination and timing, not a headcount of investors. But every rival explanation has now been tested against the data and failed, and this one fits both the timing and the shape.
Even the showflat has stopped believing it
The final tell. Developers' own launch pricing has historically built the size-psf slope in. Within the same new launch, the shoebox premium ran +11.0% in 2016 and +11.1% in 2017. By 2023 and 2024 it was +6.6% and +6.8%. In 2025 it fell to +1.4%, and in the first half of 2026, across the seven launches measurable, −5.3%.
The people who set prices for a living have been pricing the rule out for a decade, and this year they priced it the other way.
What this means for you
If you are buying a shoebox unit: "the psf is high because it's small" is no longer, by itself, a reason a price is fair. Compare against what family-sized units in the same building actually transact at. The old structure has inverted.
If you are selling a shoebox unit: the premium your unit type used to command has gone, so pricing by applying the old small-unit uplift to what larger units in your building fetch will leave you above the market, and sitting. This is a statement about the premium, not the price level. Shoebox psf has continued to rise in absolute terms. It has simply risen more slowly than the larger units beside it.
If you own a family-sized unit: relative to your own building, you have quietly re-rated upward. Your comparable set has shifted in your favour.
If you are an agent: any comparative market analysis that still assumes the size-psf slope is now wrong inside the very buildings it compares. The slope has to be measured per development, per year, not assumed.
Method and data notes
Population: private non-landed resale transactions (condominiums and apartments; Executive Condominiums excluded; collective sales excluded) from URA caveat data, and HDB resale transactions, as held in Realila's database on 1 August 2026. Latest private caveat in sample: 19 July 2026. Latest HDB resale: 1 July 2026. 2026 figures are part-year.
Definitions: shoebox = 400–538 sqft, matching URA's 50 sqm threshold; family-sized = 1,000–1,500 sqft; premium = median psf of shoebox units divided by median psf of family-sized units, minus one, computed within each development (and, where stated, within the same five-storey floor band, matching the granularity at which floors are reported), then taken as the median across developments. A development-year qualifies when both size bands have at least three transactions.
Known limits: the 2026 reading is part-year and rests on 24 developments; the floor-matched test rests on 35 cells; the 2026 new-launch reading covers seven projects. Market-wide psf averages were deliberately not used as evidence, because they mix buildings, locations and vintages; the within-development design exists to remove exactly that. Buyer identity is not observable in caveat data; the investor-withdrawal mechanism is supported by elimination and timing, as stated above.
Every figure in this article traces to a query against Realila's transaction database and carries the dates above. On why we work in medians rather than averages, and how medians differ from price indices, see Property Price Indices, Explained.

Correction and update notes
Correction: 2 August 2026. This article originally advised sellers that pricing off their building's psf history from three or four years ago would leave them above the market. That was wrong, and the seller paragraph has been amended. Shoebox psf levels rose over that period: across developments measured in both years, median resale psf for shoebox units was $1,526 in 2022 and $1,810 in 2025. Measured from 2017 to 2025, shoebox units gained 36% while family-sized units in the same developments gained 68%. The premium over larger units collapsed; the price level did not. The original wording conflated the two.
Correction: 5 August 2026. This article originally stated that rising interest rates had crushed the yield spread that made small units work as an income play. That was wrong. Measured across the same projects, shoebox rent per square foot has held a premium of roughly 52% over family-sized units throughout the period, while the sale premium collapsed, so gross shoebox yield rose from 3.56% in 2017 to 4.30% in 2025, and its advantage over family-sized units roughly doubled. The elimination of composition, floor effects, space preference and supply still stands, and investor withdrawal remains the explanation left standing; but the reason given for it was not supported. Transaction cost, principally the additional buyer's stamp duty increases of December 2021 and April 2023, is a better candidate than running yield, and is stated as a candidate only. The full rental analysis is set out in Shoebox units lost their price premium and kept their rent premium.
Definition update: 4 August 2026. This article originally defined a shoebox as 400–600 sqft and the comparison band as 1,200–1,600 sqft. It now uses 400–538 sqft, matching URA's 50 sqm threshold (the same threshold URA's own planning guidelines use, and which this article cites) and 1,000–1,500 sqft for family-sized units, which is how that stock is understood in this market. Both changes bring this article into line with the rest of the series. All figures have been re-run and the finding is unchanged: the within-development premium still crosses zero in 2025, the paired-development test still compresses, and so does the floor-matched test. Coverage is comparable to the original: the paired test rests on 49 developments against 60 before, and the floor-matched test on 35 cells against 65.

More from Realila
- A new 3 bedroom outside central rents for more per square foot than a 26-year-old one in prime, and that first became true in 2020
In 2025 a three-bedroom in a building under five years old rented for S$4.92 per square foot outside central, against S$4.02 for one over 26 years old in the core central region. In 2019 the comparison ran the other way. The age premium roughly doubled over nine years, from 1.25 times to 1.65, and in 2020 it grew large enough to overtake the thing everyone assumes decides rent.
- 95% of three-bedroom owners who sold since 2020 made money, and the median gain was $450,000
Of 27,663 three-bedroom condominiums bought and resold, 95.4% sold for more than the owner paid. The median gain was $450,000, or 33.7%, over a median hold of 9.6 years. That works out at 3.5% a year. The losses are concentrated: in the core central region one owner in ten sold below what they paid, and the median loss there was $320,000.
- A new 3 bedroom condo is 1,012 sqft and a resale one is 1,259, a difference of 247 square feet
Across nine years, the median new-launch three-bedroom measured 1,012 sqft and the median resale one 1,259. The gap is about a quarter of the smaller home. It narrowed to 162 sqft in 2023 and has widened again since. Resale three-bedrooms have lost five and a half to seven square metres since 2017 in every region, which is a real decline and a small one.
