One Chuan Grove Buyer's Guide

Step 1: Understand the project in one minute

One Chuan Grove is a 99-year leasehold condominium of 1,056 homes at Chuan Grove, off Lorong Chuan, in District 19. According to the ERA project highlights, the homes sit in 5 blocks of up to 27 storeys on about 30,345 sqm of land, with layouts from 1-bedroom to 5-bedroom, plus 7 shops and a childcare centre within the development. It is being developed by Chuan Grove Pte Ltd, a joint venture of Sing Holdings and Sunway Developments, on two adjacent Government Land Sales plots. The nearest MRT is Lorong Chuan on the Circle Line, about 250 m or 3 minutes' walk away. The preview opens on 13 February 2027 and booking day is 27 February 2027. A tentative unit schedule runs from a 1-bedroom of about 474 sq ft to a 5-bedroom of about 1,561 sq ft, and completion is estimated for end 2030. Prices, the exact address and the TOP date itself are still to be confirmed. The project details page has the full summary.

Step 2: Decide whether the profile fits you

Ask yourself how the project's known features match your priorities:

• Location: Do you work, study or have family along the Circle, North East or North-South Lines? Serangoon and Bishan interchanges are each one stop from Lorong Chuan.
• Neighbourhood: Do you prefer a quiet residential street to a busy town centre? Lorong Chuan is mainly residential, with NTP+ next door, NEX and Junction 8 one MRT stop away, and Serangoon Gardens a short drive.
• Family needs: Do you have young children? The development includes a childcare centre, the ERA project highlights list 4 primary schools within 1 km (CHIJ Our Lady of Good Counsel, Kuo Chuan Presbyterian, St. Gabriel's and Yangzheng, indicative until the address is confirmed), and the Australian International School is directly opposite.
• Facilities: Will you actually use padel, tennis, pickleball, golf simulators and a large gym? If so, you get more value from a sports-led facilities programme.
• Scale: Are you comfortable in a large estate of over a thousand homes and 5 tall blocks, with the shared amenities and community that brings?
• Unit size: Most homes in the tentative schedule are 2-bedroom (about 581 to 710 sq ft) or 3-bedroom (about 807 to 1,001 sq ft), with 4-bedroom and 5-bedroom options up to about 1,561 sq ft. Is there a type that fits both your household today and how it may change?
• Timing: Can you wait until completion? It is estimated for end 2030 and the TOP date is still to be announced, so plan for a wait of close to four years after booking.

If most answers are yes, One Chuan Grove deserves a close look at preview.

Step 3: Work out your budget

Your budget is set by three things: how much you can borrow, how much cash and CPF you can commit, and the stamp duties and other costs of the purchase.

1. Use the mortgage calculator to estimate monthly repayments at different loan sizes.
2. Use the stamp duty calculator to estimate duties for your buyer profile.
3. Use the progressive payment calculator to see how payments spread across construction.

Analysts' early view, as reported in 2025, is an average of about $2,700 to $2,800 psf for One Chuan Grove, with earlier estimates of $2,600 to $2,750 psf. That is an estimate, not a developer price, but it gives you a rough frame for shortlisting unit sizes. Getting an in-principle approval from a bank before the preview makes decisions much easier.

Step 4: Compare with alternatives

No decision should be made in isolation. Compare One Chuan Grove with:

• Resale condominiums in District 19, which offer immediate occupation but shorter remaining leases and older facilities
• Other new launches in the OCR, which may differ in location, MRT distance, facilities and developer
• Staying put, if your current home still meets your needs and the timing is not right

When comparing prices, match unit types and sizes, and consider the remaining lease. A new 99-year lease and a resale project with decades already used are not directly comparable on psf alone.

Step 5: Prepare for the preview

The preview opens on 13 February 2027 and booking day is 27 February 2027, so you have about two weeks between seeing the units and committing. Before you visit the showflat:

• Shortlist two or three unit types based on your household size
• Decide your priorities between floor height, facing and layout
• Prepare questions about the open items: the exact address, whether the tentative unit schedule has changed after approval, how the 1 km school list holds against the final address, and the TOP date
• Bring your financing details

At the preview, review the site plan alongside the floor plans so you understand what each stack faces. Ask how units will be allocated and what the booking process involves.

Step 6: The purchase timeline

For a new launch like One Chuan Grove, the usual sequence is:

1. Preview and booking: you view the showflat, choose a unit and receive an option to purchase on payment of the booking fee.
2. Exercising the option: within the stated period, you sign the sale and purchase agreement and pay the next instalment. Stamp duties fall due within a set time.
3. Construction: progressive payments fall due at each certified stage. Your bank loan begins disbursing after the early stages.
4. TOP: the project is completed and you collect your keys. Defects inspections follow.
5. Legal completion: the final payment is made and title is transferred.

The exact periods and amounts are set out in the sale documents and in the table on the payment scheme page. Always have a conveyancing lawyer review the documents.

Step 7: Think long term

A home purchase is a long commitment. Consider how your household may change over the coming decade: children growing up, parents moving in, or a change of workplace. Think about whether the unit you choose will still suit you, and how it might appeal to future buyers or tenants if your plans change. We cannot predict prices, but a well-chosen layout, sensible facing and good transport access are qualities buyers have tended to value over time.
