One Chuan Grove vs Chuan Park: What the psf Comparison Does and Does Not Tell You

The headline numbers

In dollar terms, the gap is roughly $121 psf at the low end and $221 psf at the high end. For a 1,000 sq ft home, that translates to about $121,000 at one end and $221,000 at the other. On the earlier estimates of $2,600 to $2,750 psf, the gap was much narrower, about 0.8% to 6.6%. The movement between the two sets of estimates is a reminder that the analyst range itself is the main source of uncertainty, not the benchmark.

Why a launch average is not a price

A launch-weekend average is the mean psf of the units sold in that window. It depends heavily on which units were sold. If a project sold proportionally more small units, which typically carry higher psf, its average rises. If it sold more large family units, which carry lower psf but higher quantum, its average falls.

That is where the two projects differ most. According to EdgeProp, two- and three-bedders made up 92% of Chuan Park's launch-weekend sales. One Chuan Grove's tentative schedule, published in the ERA project highlights of 3 November 2026, puts two- and three-bedders at about 74% of homes, with 240 four-bedders and 27 five-bedders making up roughly 25%. By our arithmetic, the average home on that schedule is about 891 sq ft. A larger share of big units tends to pull a project's average psf down, so if One Chuan Grove sells in line with its schedule, its headline average could understate how like-for-like units compare with Chuan Park.

A second issue is what each figure measures. The Chuan Park number describes actual sales in one weekend. The One Chuan Grove figures are analysts' expectations of average launch pricing, made well before any price list exists. Strictly, we are comparing an outcome with a forecast.

Land cost as the anchor

Another way to sense-check estimates is to look at the land. One Chuan Grove's two plots were awarded at $1,376 and $1,331 psf ppr, giving a blended rate of about $1,354 psf ppr by our arithmetic. On the analysts' newer range of $2,700 to $2,800 psf, land would represent roughly 48% to 50% of the average selling price.

That ratio is a rough indicator rather than a precise measure, because land psf ppr and selling psf are calculated on different floor area bases. Still, it gives a sense of why developers rarely price far below their cost base. With land at that level, plus construction, financing, marketing and margin, the selling price has to clear a meaningful threshold for the project to work commercially.

We do not have comparable land data for Chuan Park in our verified sources, so we cannot make a like-for-like land-to-price comparison between the two projects. That is a gap we prefer to acknowledge rather than fill with assumptions.

Timing and market context

Launch pricing reflects conditions at the time of launch. Chuan Park launched in November 2024. One Chuan Grove's preview opens on 13 February 2027, with booking day on 27 February 2027, about 27 months later by our count. Over that interval, construction costs, interest rates, buyer sentiment and competing supply can all move. A gap in psf between two projects launched at different times partly reflects those changes rather than any difference in quality or location.

For this reason, analysts often talk about "price discovery" at a new launch. The first weeks of sales reveal what buyers are actually willing to pay, and that can differ from pre-launch estimates in either direction.

Physical differences worth measuring

Beyond the numbers, physical differences between projects affect value:

• Walking distance. The ERA project highlights put Lorong Chuan MRT about 250 metres, or 3 minutes' walk, from One Chuan Grove. Compare the actual walking route for each project rather than straight-line distance.
• Scale. 1,056 homes in 5 blocks, four of 27 storeys and one of 24, is a large development, slightly larger than Chuan Park's 916 units. Scale affects facilities, maintenance cost sharing and how many units compete on the resale and rental market later.
• Facilities. One Chuan Grove's preliminary list includes two padel courts, a tennis court, golf simulators and an 800 m jogging track. Whether these add value for you depends on whether you will use them.
• On-site convenience. The highlights list 7 shops and a childcare centre within One Chuan Grove, plus the Australian International School across the road. These matter to some buyers and not at all to others.
• Completion timing. One Chuan Grove's completion is estimated for end 2030, so buyers are paying today for a home they will receive years later.
• Stack orientation and road exposure. These vary within each project and can matter more than project-level averages.

A practical method for your own comparison

When the price list is released, try this:

1. Choose the unit type you are interested in, for example a three-bedroom.
2. Find recent transactions of the same unit type at Chuan Park and nearby resale projects.
3. Compare psf and quantum for similar floors and facings.
4. Adjust mentally for remaining lease, completion timing and facilities.
5. Decide what premium, if any, you are comfortable paying for the newer project.

This like-for-like method is far more reliable than comparing project-level averages.

What this means for buyers

The headline comparison suggests One Chuan Grove may be priced somewhat above Chuan Park's launch average, if the analysts' early view proves accurate. But the estimates have already moved once, the two figures measure different things, and the unit schedule is still tentative. The sensible approach is to treat current estimates as a budgeting guide and wait for actual unit prices before forming a view on value.
