Quick answer
A four-room flat at Block 1A Cantonment Road, Pinnacle@Duxton, was registered at S$1,588,000 in October 2026, with an approximate floor area of 95 sqm. As checked on 8 October 2026, it was the highest four-room total price in HDB's resale dataset covering January 2017 onwards. This is a ranking within that series, not an unrestricted all-time national record across all flat types.
The transaction: what the official row shows
HDB's registration-date dataset records S$1,588,000 for a 4 ROOM Type S1 flat at Block 1A Cantonment Road, with a floor area of 95.00 sqm and a storey band of 28 to 30. The lease commenced in 2011 and the recorded remaining lease is 83 years 04 months.
SLA's HDB estates directory identifies Blocks 1, 1A, 1B, 1C, 1D, 1E, 1F and 1G Cantonment Road as The Pinnacle @ Duxton. The directory entry used here was updated 7 August 2023; it identifies the estate and provides no pricing information.
The floor area is approximate, and the storey band is a range rather than an exact floor; the public data does not identify the unit. HDB describes the prices as indicative and excludes some transactions that may not reflect full market price. Renovation, orientation, view, condition and cash over valuation are not established by the row. October 2026 is the registration month, not an exact agreement or completion date.
The next-ranked four-room flat, and why the gap is not a price move
The next-highest four-room price in the same dataset was S$1,550,000, registered in May 2026 at Block 1C Cantonment Road. That flat had a floor area of 96.00 sqm and a storey band of 40 to 42, compared with 95.00 sqm and 28 to 30 for the October transaction.
The S$38,000 gap compares two different flats registered in different months. It is not an appreciation rate, and the public records do not establish why the prices differed.
Per sqm, per sq ft: the unit that changes the number
The registered price works out to S$16,715.79 per sqm, or approximately S$1,552.95 per sq ft (about S$1,553 psf). These figures are derived from the official price and approximate floor area, rounded to two decimals; they are not HDB-published unit prices.
Use the same area unit when comparing flats. A highest-total-price ranking does not establish a price-per-square-foot record.
What this transaction does not establish
A registered sale can inform a comparable set, but it is not a valuation of another home. One transaction also does not establish a wider market trend or explain a premium.
Planning considerations for buyers and sellers
For buyers, compare recent transactions for the same flat type, checking area, storey band and remaining lease. Keep total price and price per square foot separate: a larger flat can cost more overall while having a lower unit price.
Review your available cash and financing before agreeing on a price. The guides to HDB cash over valuation and HDB loans versus bank loans explain the checks to consider alongside your transaction comparisons.
For sellers, a nearby high registered price is context, not a guaranteed target. Review your home's position, sale proceeds and next-home plans against your household's actual circumstances before committing.
