Chuan Grove vs Chuan Park — The $142,000 Difference Nobody Told Buyers at the Showflat
Two condos. Same street. Same MRT. 200 metres apart. Chuan Park launched at $2,586 psf — and buried 50–70 sqft of AC ledge and void inside that strata area. At that PSF, the concrete outside the living room window cost the buyer $142,000. Chuan Grove launches Q3 2026 fully harmonised. Every square foot is liveable. This is the GFA comparison every D19 buyer needs before signing anything.
Chuan Park (99yr, 916 units, launched Nov 2024) is pre-GFA harmonisation — AC ledges and void spaces are included in the strata area you pay for at full PSF. At $2,586 psf, a 3BR buyer paid approximately $142,000 for concrete they cannot live on. Chuan Grove (GLS, ~555 units, launching Q3–Q4 2026) is fully harmonised — estimated $2,650–$2,750 psf on 100% liveable floor space. Same Lorong Chuan MRT, same four 1km-ballot schools, same street. The GFA difference is the entire case for waiting.
Comparing These Two Projects — James Runs the Real Numbers
The headline PSF comparison misrepresents the actual cost. James calculates the true liveable PSF for any unit type at both projects — then tells you whether the wait for Chuan Grove's harmonised floor plate justifies the delay versus buying Chuan Park now.
- True liveable PSF at Chuan Park — your exact unit type, not the headline average
- Chuan Grove estimated launch price range vs your Chuan Park alternative
- Full financial model: BSD + ABSD + TDSR at both price points
- Rental yield comparison — harmonised vs pre-harmonisation on the same corridor
Chuan Grove's launch is expected Q3–Q4 2026. Once the price list drops, the GFA advantage is priced in and the "is the wait worth it" question has already been answered by the market.
That the PSF comparison between Chuan Park and Chuan Grove is straightforward. It is not. Chuan Park's $2,586 psf and Chuan Grove's estimated $2,650–$2,750 psf are not comparable numbers. One includes dead space. One does not. Comparing them directly — as most buyers do — is like comparing the price of two hotel rooms where one price includes the bathroom and one does not.
The Saturday Morning Queue — A Lorong Chuan Story
When David and his wife joined the Chuan Park showflat queue in November 2024, they arrived at 7am. There were already 200 people ahead of them. They bought a 3-bedroom at $2,586 psf — thrilled to finally own something new beside Lorong Chuan MRT, the same station they had commuted from for eight years.
What nobody explained at the showflat: approximately 55 square feet of that floor area — the slab of concrete sitting outside the living room window — was the AC ledge. Fully charged to them. At $2,586 psf, that ledge cost $142,000. It cannot be furnished. It cannot be air-conditioned. It cannot be lived on. It sits outside the glass, doing nothing, collecting dust and bird droppings, for the life of the building.
Six months later, Chuan Grove was announced 200 metres down the same road. Same MRT. Same four 1km-ballot schools. Same street. No AC ledge charge. David read about it on a Saturday morning with his coffee. He messaged James asking whether he had made a mistake.
The honest answer is that David did not make a mistake — he bought a good product in a good location at a time when it was the only new option. But the GFA difference is real, and every buyer considering either project needs to understand it before they commit.

GFA Harmonisation — What the Rule Actually Changed and Why It Only Applies to One of These Projects
Before 1 September 2022, Singapore developers could include AC ledges, bay windows, void spaces and planter boxes in the strata area sold to buyers. These elements were part of the building's gross floor area — they counted toward the developer's permitted GFA — so they were passed to buyers at full PSF. A 1,000 sqft unit might contain 70–80 sqft of areas you could never furnish, air-condition or sleep in. You paid for all of it.
URA changed this. From 1 September 2022, all new GLS sites must exclude non-liveable areas from the strata area. AC ledges become common property. Void spaces, bay windows and planters are removed from the floor area that buyers pay for. Every square foot in your strata title is usable space.
Kingsford + MCC Land win the Chuan Park en bloc. En bloc acquisitions are not GLS sites — the old pre-harmonisation rules apply. Every AC ledge will be inside the buyer's strata area at full PSF.
The most buyer-friendly regulatory change in Singapore property in a decade. Every GLS site from this date must exclude AC ledges, voids and bay windows from strata area. The corridor splits into two eras at this exact date.
84% sold. 200 people queuing by 7am. The demand was real — but so was the GFA inefficiency. PropertyLimBrothers independently confirmed AC ledge is charged at full PSF. David and his wife were in that queue.
Sing Holdings + Sunway win at $703M ($1,376 psf ppr). GLS site = GFA harmonisation is a regulatory requirement. Zero AC ledge charge. Zero void charge. The quoted PSF will be 100% liveable floor plate.
Same Lorong Chuan MRT. Same four 1km-ballot schools. Same Serangoon corridor. Different floor area structure — and a fundamentally different value proposition at equivalent PSF.
What the Floor Plan Comparison Actually Shows — Where the Money Goes
A 3-bedroom unit from each project. Same corridor. Same MRT. The difference is in what the strata area includes — and what it does not.
❌ Chuan Park 3BR
~1,098 sqft quoted · Pre-harmonisation
✅ Chuan Grove 3BR
~975 sqft quoted · 100% harmonised
The GFA efficiency saving across unit types — based on Chuan Park's strata inefficiency at $2,586 psf:
| Unit Type | Est. AC Ledge + Void | Cost at Chuan Park PSF | Chuan Grove Charge |
|---|---|---|---|
| 2 Bedroom | ~40–50 sqft | ~$88K–$111K | $0 |
| 3 Bedroom | ~55–70 sqft | ~$127K–$142K | $0 |
| 4/5 Bedroom | ~70–80 sqft | ~$155K–$181K | $0 |

James's professional assessment · Not investment adviceFour 1km-ballot primary schools — St Gabriel's, CHIJ Our Lady of Good Counsel, Kuo Chuan Presbyterian, Yangzheng Primary. Rare for D19 and a genuine family buyer anchor. Not the Ai Tong or Nanyang school zone but a solid, balanced family address in a maturing corridor.
4-min walk to Lorong Chuan MRT (CC14 Circle Line). One stop to Serangoon interchange (NEL + CCL) — three lines accessible within 10 minutes. CCL loop completing 2026 boosts CBD connectivity. Paya Lebar Airbase relocation 2030 unlocks 800ha of new eastern precinct — first new GLS in this corridor in 16 years signals the transformation is beginning, not peaking.
NTP+ Mall directly opposite the site. NEX Megamall one MRT stop at Serangoon. Serangoon Gardens F&B strip within 5 minutes by car. New Serangoon Polyclinic opened 2025. Strong amenity base for an OCR corridor — not integrated MRT-level amenities, but fully serviceable without a car.
Estimated gross rental yield ~3.2–3.4% benchmarked on Forest Woods (~3.3%) nearby. 100% GFA harmonised — rental income calculated against 100% liveable purchase price, a cleaner investment calculation than Chuan Park. Land bid $1,376 psf ppr signals developer conviction. 99yr leasehold from ~2030 — long runway. Corridor yield is not exceptional but holds well for OCR given the MRT and school fundamentals.
What the Lorong Chuan Corridor Is Actually Returning
Before committing to either project, here is what neighbouring developments are yielding and where each sits on the harmonisation timeline.
| Project | Tenure | Avg PSF | Gross Yield | 2BR Rent | GFA |
|---|---|---|---|---|---|
| The Scala | 99yr · 2010 | ~$1,947 | ~3.2% | ~$3,500/mo | ❌ Pre-harm. |
| Forest Woods | 99yr · 2016 | ~$2,054 | ~3.3% | ~$3,600/mo | ❌ Pre-harm. |
| Chuan Park ★ | 99yr · 2024 | $2,586 quoted · $2,717 liveable | Est. 3.0–3.2% | Est. $4,000/mo | ❌ Pre-harm. |
| Chuan Grove ★ (est.) | 99yr · 2026 | Est. $2,650–$2,750 | Est. 3.2–3.4% | Est. $4,200/mo | ✅ Harmonised |

The harmonised floor plate matters for investors beyond the purchase price. Rental income is calculated against the quoted strata area — but tenants pay for the experience of the unit, not the strata title. A Chuan Grove tenant pays rent for a genuinely usable 975 sqft. A Chuan Park landlord's rental yield calculation includes 70 sqft of AC ledge in the denominator. Chuan Grove's yield is cleaner — and marginally better — at equivalent gross rent.

Chuan Park Now
- You need keys by 2027 — cannot wait for 2030 TOP
- The integrated MRT directly above is a non-negotiable
- You have found a specific resale unit at a price that adjusts for the GFA inefficiency
- Your TDSR window closes before Chuan Grove launches
The honest answer: For a buyer without a hard timeline constraint, Chuan Grove is the correct decision. The GFA argument is not subtle — it is $127,000–$142,000 on a 3BR. The wait is real (TOP ~2030) but the savings are structural and permanent. Chuan Park makes sense for buyers who need occupancy before 2028 or who value the integrated MRT access above everything else. Those are legitimate reasons. The PSF comparison alone is not.
Why the Launch Window Matters — Cost of Waiting After Chuan Grove Launches
The Paya Lebar Airbase relocation in 2030 is the 3–5 year catalyst for this corridor. 800 hectares of land — the largest urban transformation in Singapore since Marina Bay — opens for residential and commercial development adjacent to the eastern CCL corridor. Chuan Grove is the only new-launch project in position to capture the run-up to that announcement and the re-rating that follows.
For context on how GLS supply shapes corridor pricing — the Singapore GLS guide explains how land cost and bid counts translate to launch price floors. The Chuan Grove land bid of $1,376 psf ppr from a $703M award tells you exactly what Sing Holdings and Sunway believe this corridor is worth at launch.
David messaged me about three weeks after the Chuan Grove announcement. He had done the floor plan comparison himself and was genuinely upset — not at Kingsford, not at the industry, but at himself for not knowing about GFA harmonisation before he bought. He asked me whether he had made a mistake.
My answer was no — and I meant it. Chuan Park is a real product at a real MRT with real schools. 84% sold on launch day means a lot of very informed buyers made the same decision. But the GFA difference is not a technicality. $142,000 on a 3-bedroom is not a rounding error. It is a second car. It is two years of school fees. It is meaningful money that Chuan Grove buyers will not be paying for concrete they cannot use.
The assumption I keep seeing buyers make is that a lower quoted PSF automatically means better value. It does not. The number that matters is the cost per square foot you can actually live on. On that measure, Chuan Grove at $2,650–$2,750 psf harmonised is a better deal than Chuan Park at $2,586–$2,717 true liveable PSF — for any buyer who can accept the 2030 TOP. The ones who cannot accept the wait have a legitimate reason to choose Chuan Park. But they should make that decision knowing the real cost, not the brochure PSF.
