Primary: a One Chuan Grove school check
Buying for the schools? Check the block, not the brochure.
Tell me which school matters to you. When the site plan is out, I will show which blocks look safest for the 1km band and what you pay for them.

One Chuan Grove's brochure will show four primary schools around it. That is true. What the brochure will not show is which of its blocks sit inside 1km of each school, and for a site this large that can differ.
Short answer: Not every block at a large site is guaranteed to be within 1km of every nearby school. MOE measures from the school's land boundary to your building outline, and confirms it on OneMap in the registration year. At One Chuan Grove, St Gabriel's and Kuo Chuan Presbyterian look comfortably close, while CHIJ Our Lady of Good Counsel and Yangzheng sit nearer the line.

The four schools and how close they are
Blue: close to the 1km line, so check your block on OneMap. My estimates, not MOE figures.
| School | Straight line from the site | Margin to 1km |
|---|---|---|
| St Gabriel's Primary | About 290m | Comfortable |
| Kuo Chuan Presbyterian Primary | About 600m | Comfortable |
| CHIJ Our Lady of Good Counsel | About 870m | Check your block |
| Yangzheng Primary | About 970m | Check your block |
These are my straight-line estimates from the site, as shown on my One Chuan Grove review. They are not MOE figures. One Chuan Grove combines two land parcels into about 1,056 homes, so a block at one end can be a long way from a block at the other.
How MOE actually measures 1km
MOE measures home-school distance as the shortest distance from the boundary around the school to the outline of your residential building, using the building plan submitted for the development (MOE). Since the 2022 exercise, it has used the school land boundary rather than a single point in the school (MOE, 9 September 2021).
MOE also says distance can change, for example when building plans or school boundaries change, and that parents should check their category on OneMap's School Query service in the year of registration. A 2027 brochure is not the final word for a child starting Primary 1 years later.
Why the block matters at a big site
Within 1km gives priority in the Primary 1 phases that use distance, ahead of 1km to 2km. If a school is oversubscribed in the phase you apply in, that difference can decide the ballot.
At a site of over 1,000 homes, the schools at 290m and 600m have hundreds of metres of margin. The two near 870m and 970m do not. Depending on where the blocks sit, some may fall inside 1km of CHIJ Our Lady of Good Counsel or Yangzheng and others outside. Until the site plan and OneMap results are out, no one can tell you which.
The other rules that catch buyers
Using an address for distance priority comes with a 30-month stay requirement, and MOE checks. It says using an address only to register is viewed seriously, and that it may transfer a child to another school if it finds abuse (MOE). Factor that into any plan to buy, register and sell.
Timing matters too. One Chuan Grove is targeted to preview on 13 February 2027, and completion will be years later. If your child registers before you can move in, check MOE's current conditions for using an uncompleted property's address.

Paying a premium for a school you may not get?
Message me the school and the stack you are eyeing. I will check the distance and the price gap before you book.
WhatsApp JamesWhat to do before you book
First, when the site plan is released, ask the sales team which blocks are closest to the school you want. Second, when an address is searchable, run it through OneMap's School Query, which shows the category MOE uses.
Third, compare the price of a "safe" block with one further away. If the developer charges more for the closer blocks, you can see exactly what the school is costing you. My mega vs smaller condo comparison covers the other trade-offs of buying into a site this large.
My view
If St Gabriel's or Kuo Chuan Presbyterian is your target, One Chuan Grove gives you real margin, and I would focus on price and stack instead. If CHIJ Our Lady of Good Counsel or Yangzheng is the reason you are buying, I would not book a unit until I could see the block on OneMap.
Paying for a school belt is reasonable. Paying for one you might be 30 metres outside of is not. For how One Chuan Grove compares with the other 2027 launches in the area, see my One Chuan Grove, Chencharu and Hougang Central comparison.
Questions readers ask
Which primary schools are near One Chuan Grove?+
St Gabriel's Primary at about 290m, Kuo Chuan Presbyterian Primary at about 600m, CHIJ Our Lady of Good Counsel at about 870m and Yangzheng Primary at about 970m, measured in a straight line from the site. These are estimates, not MOE figures.
How does MOE measure the 1km distance?+
MOE measures the shortest distance from the school's land boundary to your residential building outline, based on the approved building plan. Parents should confirm their category on OneMap's School Query in the year of registration.
Will every block at One Chuan Grove be within 1km?+
Probably not for every school. St Gabriel's and Kuo Chuan Presbyterian have a wide margin. CHIJ Our Lady of Good Counsel and Yangzheng sit nearer 1km, so some blocks could fall outside. Check once the site plan is released.
Do I need to live there to use the address?+
Yes. MOE requires families using an address for distance priority to meet a 30-month stay requirement, and it carries out checks. Using an address only to register is viewed seriously.
When does One Chuan Grove launch?+
The developer targets a preview on 13 February 2027 and a launch on 27 February 2027. Analysts quoted by EdgeProp expect $2,600 to $2,800 psf. Prices are not out yet.
